Let's be honest: We rarely test the product functionality under load. But how can we be sure our end product works when our customers are using it? As we've described in our previous blog post "Combining Automated Functional and Load Testing", it often makes sense to combine functional and non-functional tests. A functional test, which works fine in idle conditions, might fail when the back-end server is under load. Just like simply stressing a back-end system may not reveal functional issues, which can only be found by an automated functional test. If we want to find those errors that only occur under load, we have to combine automated functional tests and automated load tests.
We're happy to announce that you can now combine Ranorex and NeoLoad tests!
In this blog, we want to show you how you can set up the Ranorex-NeoLoad integration and what you can do with it. But first, let's quickly cover the basics:What is NeoLoad?
NeoLoad is an automated load and performance testing tool from Neotys.
NeoLoad offers a full-fledged REST API to either remote control the execution of a NeoLoad test or transmit timing values to NeoLoad. To enable integration with Ranorex, the REST API calls are wrapped with Ranorex functions and packaged into a NuGet package for easy deployment.What do I need to enable the Ranorex-NeoLoad integration?
- Ranorex license - alternatively, you can download a free 30-day trial
- NeoLoad Professional license - alternatively, you can also use the free license
Now that you're all set, we want to show you in detail how you can:
- Set up the Ranorex-NeoLoad integration
- Use the load testing modules available with the integration
- Transmit navigation timing to a NeoLoad test
- Update meta-information in cross-browser tests
- Upgrade an existing Ranorex project with the Ranorex-NeoLoad NuGet package
First, we need to set up the integration:
- Add the NuGet package to the Ranorex project
- Extend the "app.config" file
- Right-click on "References" in the Ranorex project view
- Select "Manage Packages..."
- Search for "Ranorex" and add the "Ranorex-NeoLoad integration" package
This will automatically add the necessary libraries to the Ranorex project. The following code modules will now appear in the module browser:
Step 2: Extending the "app.config" file
To ensure the Ranorex project is properly created, you need to extend the 'runtime' section in the 'app.config' file in the Ranorex project with the following information:
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1" xmlns:bcl="urn:schemas-microsoft-com:bcl"> <dependentAssembly bcl:name="System.Runtime"> <assemblyIdentity name="System.Runtime" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-184.108.40.206" newVersion="220.127.116.11" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Threading.Tasks" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-18.104.22.168" newVersion="22.214.171.124" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Net.Http" publicKeyToken="b03f5f7f11d50a3a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-126.96.36.199" newVersion="188.8.131.52" /> </dependentAssembly> </assemblyBinding>
Copy this code and enter it in the 'runtime' section in the 'app.config' file, right after the line <enforceFIPSPolicy enbaled="false" />:
Your 'app.config' file should now look like this:
You can now use the modules, which are included in the NuGet package, freely within the Ranorex test automation project.Modules included in the Ranorex-NeoLoad NuGet package
The following modules, and their individual variables, are included in the Ranorex-NeoLoad NuGet package:
This module establishes a connection to the NeoLoad runtime API. This API is used to remote control a running NeoLoad test. It must be initialized before using the following modules: Start/StopNeoLoadTest and Add/RemoveVirtualUsers.Show the variables available for this module RuntimeApiUri: The Uniform Resource Identifier (URI) of the NeoLoad REST service.
ApiKey: Key stored in NeoLoad to avoid unauthorized access to the REST API. If no key is in use, this variable can be left blank.
Select Edit > Preference to access these variables in NeoLoad.
This module establishes a connection to the NeoLoad data-exchange API. This API is used to transmit external data to a running NeoLoad test (it is not active if no test is running). This module must be initialized before the modules Start/StopNeoLoadTest and Add/RemoveVirtualUsers.Show the variables available for this module The following three values provide meta information for a running test and can be used in the "filter" functionality within NeoLoad test results.
Location: The location, where the functional test is performed (e.g., Graz, London, Office XYZ, ...)
Hardware: The hardware used where the functional test is running (e.g., Intel i5-5200u). A string describing the utilized operating system is automatically appended to the string defined in "Hardware".
Software: The software, tested in the functional test. When testing a browser, it is recommended to hand over the browser name. When performing a cross-browser test, it is recommended to bind this variable to the column specifying the browsers.
DataExchangeApiUri: The URI of the NeoLoad REST service.
ApiKey: A key stored in NeoLoad to avoid unauthorized access to the REST API (if no key is in use, this variable can be left blank).
Select Edit > Preference to access the last two variables in NeoLoad.
This module starts a NeoLoad test scenario. You need to define the scenario in NeoLoad before.Show the variables available for this module Scenario: The scenario, as defined within the NeoLoad test, that should be started.
Timeout: The maximum amount of time (in hh:mm:ss) given to Ranorex to start a specific test (recommended value: 00:01:00).
Interval: The time interval (in hh:mm:ss) after which Ranorex retries to start a specific test (recommended value: 00:00:10).
Important: Please make sure to add a leading 0 before a single digit number when entering the timeout and interval values.StopNeoLoadTest
This module stops the currently running NeoLoad test.Show the variables available for this module Timeout: The maximum amount of time (in hh:mm:ss) given to Ranorex to start a specific test (recommended value: 00:01:00).
Interval: The time interval (in hh:mm:ss) after which Ranorex retries to start a specific test (recommended value: 00:00:10).
Important: Please make sure to add a leading 0 before a single digit number when entering the timeout and interval values.AddVirtualUsers
This module adds virtual users to a population, defined in a NeoLoad test scenario. This module can only be used when a test is already running.Show the variables available for this module Population: The population, as defined in the NeoLoad test scenario, virtual users will be added to.
Amount: The amount of virtual users that should be added to the given population. RemoveVirtualUsers
This module removes virtual users from a population, which is defined in a NeoLoad test scenario. This module can only be used when a test is already running.Show the variables available for this module Population: The population, as defined in the NeoLoad test, virtual users will be removed from.
Amount: The amount of virtual users specified that will be removed from the given population. Transmit navigation timing data from any browser to NeoLoad
Opening a website is related to a certain latency. This latency depends on various factors, such as the network connection or the browser used. It can be measured with the "Navigation Timing" API, which is offered by all browsers. If you evaluate these timing values, especially when the website is under load, you can localize potential bottlenecks. Eliminating the identified bottlenecks will ultimately improve the user experience.
The NuGet package offers a mechanism to calculate these timing values and transmit the results to NeoLoad. You can find a more detailed description of the navigation timing here. The timing values are calculated by the Ranorex/NeoLoad Nuget package:
Highlighted in green, you can see the timing values that are calculated by Ranorex and submitted to NeoLoad.
To transmit the timing values, you need to drag and drop the repository root element, which represents the DOM of the website under test, into the action table in Ranorex Studio. Once the NuGet package is added to the Ranorex project, the additional entry "SendNeoLoadTimingValues" will appear in the "Dynamic Actions" list.
Please note: This entry only appears if the root element was created after the NuGet package was added to the Ranorex project. You can find a description of how to enable the NeoLoad "capability" in an existing repository here.
The "SendNeoLoadTimingValues" action accepts a "transaction name" as an argument. We recommend using the current page as a transaction name in the Ranorex action table. As soon as NeoLoad receives the timing values of this transaction, a tree with the root node containing the Ranorex test suite is automatically created. Another subfolder is automatically created for the respective transaction name. This folder contains the timing values transmitted from Ranorex.
Important: Please make sure to initialize the module "ConnectToDataExchangeApi" before you use the module "SendNeoLoadTimingValues". Otherwise, an error is thrown.
You can drag the data series into the graph board in NeoLoad to visualize it. If you've provided meta-information, such as "Hardware", "Software" or "Location" in the "ConnectToDataExchangeApi", you can now use this information to filter timing values transmitted from Ranorex.Update meta-information in cross-browser tests
If you execute the test in multiple browsers, you have to update the filter options in NeoLoad by calling the "ConnectToDataExchangeApi" module again. To do so, bind the data column, which specifies the browsers, with the "Software" argument from the "ConnectToDataExchangeApi" module. You can now compare timing values from different browsers.
Exemplary Ranorex project structure
In the screenshot below you can see an example of how you can use the modules provided in the NuGet package within a Ranorex test project:
As you can see, a connection to the runtime API is established in the global setup section. The login information take the form of global parameters.
At the very beginning, "StartNeoLoadTest" starts the NeoLoad test scenario. The following test case is data driven and provides the number of virtual users that will be added to the test. These values are provided in "AddVirtualUsers". The inner loop is a cross-browser loop. It defines the browsers in which the test will be executed.
Please note: The module "ConnectToDataExchangeApi" can be called multiple times to update the current browser with the filter feature in NeoLoad.Upgrade an existing Ranorex project with the Ranorex/NeoLoad NuGet package
If you add the NuGet package to an existing Ranorex project, which already contains a Ranorex Object Repository with repository elements, the modules provided by the NuGet package are automatically available in the module browser. In this case, the "SendNeoLoadTimingValues" option won't be available in the "Dynamic Actions" list for the already existing repository items. Perform the following steps to enable this option:
1. Open the RanoreXPath editor
2. Switch to "Browser & Results"
3. Drag and drop the root element from the Ranorex Spy to the matching root element in the Ranorex Object Repository.
Now, the "SendNeoLoadTimingValues" will be available in the Dynamic Actions list for the repository root element that describes the website DOM.Conclusion
In this blog, you've learned how you can combine Ranorex and NeoLoad tests. You've seen the modules and variables that are available with this integration and how you can transmit timing values to a NeoLoad performance tests. Now, you will be able to validate critical business cases under load conditions to ensure system stability under real usage conditions and identify potential bottle-necks across technology borders.Further Resources

At conferences, we often get asked how you can increase risk coverage and ensure highest user experience. Fact is that budget constraints and time pressure force testers to achieve maximum results using a minimum of resources. In reality, there’ll always be those problems that occur once the product is released. These are difficult to predict, but can greatly impede the user experience. In this blog we want to show you why it often makes sense to combine functional testing and load testing.Why performance and functionality of a system are important
First and foremost, an app or website has to work correctly. In an online shop, the user has to be able to open the site, select the desired product, add it to the shopping cart and complete the order. If one of these steps doesn’t work, the user cannot buy the product. This leads to poor user experience (UX) and worst case, results in a lost customer. But also the reliability of a system influences the UX. A site has to work! But it has to work over and over again, even under varying conditions. It has to work when the traffic increases, different browsers are used, but also if new functionalities are added. If a website does not offer reliable performance, customers will shy away from using it. Fact is that functionality and performance are important to the success of your website.
Ideal case: you test every possible scenario. But tests take time and no one’s got time to spare. We need to decide which tests to automate, when and how often. A risk assessment is crucial to pick the right test cases.Assess risk contribution of potential issues
When creating a test strategy with maximum risk coverage, you have to estimate the probability that certain issues occur and assess their impact on the system. Some functional issues only surface if the system is put under stress. These are particularly hard to predict. However unlikely these issues may be, their impact may just not be worth the risk. Just think about the consequences if a ‘Buy’ button in the shopping cart doesn’t appear on Cyber Monday, when thousands of people access the site at the same time.Separated automated functional and load testing
Typically, testing types are clearly separated. This is also true for automated functional and load testing. Automated functional testing enables you to automatically and reliably verify the system’s functionality. Load testing verifies the system’s behavior under peak load. A typical sequence of tests could look like this:
With functional automated testing, you first validate if your website or app works as expected. Next, the team tries to manually find bugs while exploring the software. These tests are performed while the system is idle. As soon as they succeed, a performance test verifies the system’s behavior in real usage conditions – varying traffic, multiple users, increased network load, etc. Finally, the team manually validates the system using simulated load conditions.Downsides of separating load from functional testing
First of all, this testing scenario includes two sections of manual testing. Naturally, manual testing takes a lot of time, is brittle and reduces test coverage. Additionally, your automated functional tests will only provide you with feedback on how your system works in idle conditions. You won’t be able to evaluate the load test results for functional correctness. It is not until the very end of the testing process that you will find out how your system works under stress, in real usage conditions.Benefits of combining automated functional and load testing
In reality, there will always be those bugs that occur if certain conditions correlate: the link breaks if the site traffic increases or the site content only loads after a refresh. To increase risk coverage and find those functional issues that manifest under load, we need to include load in our automated functional tests. A testing process could now look like this:
You can now incorporate a sustained load in your automated functional tests. This approach to testing enables you to reliably test key functionalities that are most valuable to your business under realistic usage condition. You will be able to identify those issues that only manifest under load early in the testing process, which makes it easier to fix them and will ultimately save you a lot of time. But more importantly, you will finally get tremendously important insights on how end users experience your website. Ultimately, it is up to you to assess the potential impact certain issues may have on your system and if combining these two testing types makes sense in your individual case.
We would like to announce that you can now combine Ranorex functional tests with NeoLoad performance tests!
We’ll soon publish a blog post with detailed instructions on how to combine Ranorex with the NeoLoad performance testing tool! Please note that you will need a NeoLoad license to enable this integration.
You can now already register for our free webinar on “Combining automated functional and load testing”, which will take place on November 09, 2016. In this webinar we will explain in detail how the Ranorex-NeoLoad integration works and what the benefits are.
In software engineering, continuous integration means the continuous application of quality control processes — small units of effort, applied frequently.
In this blog we’ll show you how to set up a CI job with Hudson/Jenkins that automatically builds and executes your Ranorex automation as well as automatically sends out the generated test reports for every committed change in a Subversion repository.
- Advantages of Continuous Integration Testing
- Add New Job
- Run Job
- Add Repository Hook
Continuous integration has many advantages:
- When tests fail or bugs emerge, developers can revert the codebase to a bug-free state without wasting time for debugging
- Developers detect and fix integration problems continuously – and thus avoid last-minute chaos at release dates
- Early warning of broken/incompatible code
- Early warning of conflicting changes
- Immediate testing of all changes
- Constant availability of a “current” build for testing, demo, or release purposes
- Immediate feedback to developers on the quality, functionality, or system-wide impact of their written code
- Frequent code check-ins push developers to create modular, less complex code
You can find a download link and installation description for Hudson and Jenkins here:
In this blog post we are going to use Jenkins as CI tool. There shouldn’t be much of a difference when using Hudson.
As Jenkins or the nodes executing the CI jobs normally are started as Windows services, they do not have sufficient rights to start UI-applications.
Please make sure that Jenkins as master and its slave nodes, where the Ranorex automation should be triggered, are not started as a service.
For the Jenkins master, open the “Services” tool (which is part of the “Administrative Tools” in the control panel), choose “Jenkins” service, stop the service, and set the “Startup type” to disabled:
Use the following command to start Jenkins manually from the installation folder:
java -jar jenkins.war
After starting Jenkins, use this address to access the web interface:
To configure your Jenkins server, navigate to the Jenkins menu and select “Manage Jenkins” -> “Configure System”:
Note: It is necessary to have the Ranorex main components – and a valid Ranorex license – installed on each machine you want to build and execute Ranorex code.Source Code Management
As mentioned before, we are going to use a Subversion repository as base of our continuous integration process.
In this sample, we have two solutions in our repository: the application under test and as the automated Ranorex tests.
To start the application under test from your test project, simply add a new “Run Application” action to your action table in Ranorex Studio, which starts the application under test, using a relative path to the repository root:
As we want to build our code for each committed change within our SVN repository, we need a Subversion as well as a MS Build plugin for Jenkins. An additional mail plugin will make sure that a mail is sent with each build.Install Plugins
Open the “Manage Plugins” section (“Manage Jenkins” -> “Manage Plugins”), choose the following plugins from the list of available plugins and install them if they are not installed already:
- MSBuild Plugin
- Email Extension Plugin
- Subversion Plugin
The installed plugins also need to be configured. To do so
- open the “Configure System” and configure the “Extended E-Mail Notification” plugin. To do so, set the recipients and alter the subject and content (adding the environment variable $BUILD_LOG to the content will add the whole console output of the build and the test to the sent mail),
- configure the “E-mail Notification” plugin by setting the SMTP server.
- and navigate to “Global Tool Configuraiton” and configure your “MSBuild” plugin by choosing the “msbuild.exe” installed on your machine.
Now, as the system is configured, we can add a new Jenkins job, which will update the checked out files from a SVN repository, build both the application under test and the Ranorex automation project, execute the application under test as well as the automation code and send a mail with the report file attached.
Start by creating a new item. Choose “Build free-style software project” as job type and enter a job name:
Next, we have to check out the source of both the application under test and our test automation project. Start with choosing Subversion as source code management tool. Then, enter the repository holding your application under test as well as your test automation project. Finally, choose “Use ‘svn update’ as much as possible” as check out strategy:
With this configuration, the application under test as well as the test automation project will be checked out and updated locally.Add Build Steps
Now, as the source code management is configured, we can start with processing the updated files.
First of all, let’s add MSBuild steps for both projects:
Choose your configured MSBuild version and enter the path of the solution file relative to the repository root (which is the workspace folder of the Jenkins job) for both the automated and the automating project:
With adding these two build steps, the executables will be automatically built. Now the newly built application should be tested.
This can be accomplished by adding a new “Windows batch command” that starts the test suite executable:
As you can see, some command line arguments are passed to the test suite executable.
In this sample, the command line arguments “/zr”, which triggers the test suite executable to generate a zipped report file, and “/zrf:.ReportsReport-Build-%BUILD_NUMBER%.rxzlog”, which defines the name and the location of the generated zipped report file, are used.
You can find a list of all available command line arguments in the section “Running Tests without Ranorex Studio” in our user guide.
The test suite executable returns “0” on success and “-1” on failure. Based on this return value, Jenkins will mark the build as successful or failure.
After building and executing the application under test and the Ranorex test script, we will send an email which informs us about the success of the triggered build.
This email should include the zipped report file, mentioned before, as attachment.
To do so, add the new post-build action “Editable Email Notification”, choose the report file location defined before as attachment, and add triggers for each job status you want to be informed about. In this sample, an email will be sent if a job has failed or succeeded.
Once you’ve completed these steps and saved your changes, check if everything works as expected by clicking “Build now”:
After running the generated job, you will see all finished builds within the build hierarchy. Icons indicate the status of the individual builds.
You can view the zipped report files of all builds by opening them in the local workspace (“Workspace/Reports”):
As configured before, an email will be sent to the specified email address(es), including the console output in the email text as well as the generated zipped report file as attachment.Add Repository Hook
Now we can manually trigger a build. As we are working with Subversion, it would be beneficial to trigger the script for each commit.
To do so, you can add a server side repository hook, which automatically triggers Jenkins to start a new build for each change committed, as described in the subversion plugin documentation.
Alternatively, you can activate polling of the source code management system as build trigger in your Jenkins job configuration.
As shown in following picture, you can define the interval, after which the source code management will be invoked (e.g. 5 minutes after every full hour):
Following the steps above you will be able to easily setup a continuous integration process performing the automated test of the application you develop. Each commit will now trigger an automated test run. Once the test run has finished, you’ll instantly receive a mail with the Ranorex test report.

Apple’s iOS 10 update for iPhone and iPad lives up to its milestone software version number and implements major changes to your daily phone and tablet routine.
Benefit from features such as:
- A fully redesigned lock screen
- Siri open for developers
- Huge changes and new features for messages
- A redesigned Apple Music app
- Deletable stock apps
- A completely new Home app for HomeKit
- and many more features.
We are delighted to announce that with our latest release, Ranorex 6.1, iOS 10 is supported.
Upgrade to the latest OS on your mobile devices now to start automating your cutting edge mobile app tests with Ranorex!
We’re happy to announce that we’ve released Ranorex 6.1! This new generation of functional test automation is now fresh and polished to make working in teams even easier! Next to remote test execution, improved test suite file format and Git integration, this software update introduces an intuitive setting storage and a progressive report preview. Let’s have a look at the benefits, shall we?Solution Settings Ensure everyone in a team uses the same settings when working on a test automation project.
You can now save technology-specific solution settings directly in the test automation solution, while user settings can still be stored locally. This brings some rather fantastic benefits with it:
- You can check in your settings together with the solution into a version control system. This makes it easier to share solutions with other team members and, ultimately, to work together on them.
- Are you working on multiple test automation projects? Very likely, each is in its own test environment. Now, when you switch between solutions, you don’t have to manually adjust the settings.
Have fun sharing your settings and working together on test automation projects!
We’ve all been there. You’d like to know how many test cases have failed, but it could take hours until the test run is complete and the full report is available. You’d need this information to react early to failed test cases – or maybe just to have a peace of mind before you go home. Trust us, we get it. So here’s what we’ve done: During test execution, test results are saved in configurable intervals. So whenever you feel like it, you can preview the report from anywhere without disrupting the test run. Enjoy!
For a full list of new features and enhancements, please view our Release Notes. This software update is available now and included in software maintenance at no additional costs.
Ranorex is more than just a simple capture and replay tool. It is a versatile test automation software that offers a range of tools suitable for every skill level. While you don’t need any programming skills to easily create and maintain your tests with the Ranorex Recorder, you can also manually create your automated tests.
What are the benefits of manual test case creation?
- Keep your Ranorex Object Repository structured and easily maintainable from the start.
- Create robust test cases that uniquely identify dynamic IDs.
- Ensure only those UI elements you want to test are available in your Ranorex Object Repository.
- Automate complex test scenarios in code using the Ranorex Object Repository.
In this example, we’ll use the KeePass as application under test (AUT). This open source password manager application is one of our sample applications delivered with Ranorex Studio, so you can easily recreate this example.
In this blog, we’ll show you how to
- generate a Ranorex Object Repository containing exactly those UI elements you want to address in your automated test,
- drag and drop the resulting repository items to your action table or
- drag and drop items directly into your user code to represent the workflow you want to test.
The Ranorex Object Repository manages the UI elements of your automated test. A repository item is automatically created in this central Ranorex Object Repository when you record or track a UI element. If you change a repository item, these changes are automatically applied in the code as well as in the recording module.
Start by opening your solution and add an empty recording module. You will notice that the central Ranorex Object Repository of your test automation project is displayed directly below the action table. You can now add UI elements to the repository using the ‘Track’ button in the Ranorex Object Repository.
Enhancing the RanoreXPath
You can alter the RanoreXPath of specific repository items to make them more robust. Simply open the path editor and click on the ‘Edit’ button next to the item. For more information about the RanoreXPath, please have a look at the user guide chapters RanoreXPath and RanoreXPath Editor. If you’d like to know how to best enhance the object recognition of your AUT using the RanoreXPath operators, check out the blog post RanoreXPath – Tips and Tricks.Keep your repository clear and structured
If your Ranorex Object Repository contains many objects, it’s particularly important to keep it clearly structured and organized. Here are two tips:
Rename repository items
Each UI element within the repository can have a logical user-defined name. Renaming repository items and giving them logical names will make it easier to understand test automation code and report files.
Create Logical Folders
You can also create logical folders to structure and group UI elements that logically belong together. For detailed instructions on how to structure your Ranorex Object Repository, please check out our user guide chapter Adapting an Existing Repository.
As your Ranorex Object Repository now contains multiple UI elements, you can add actions to the recording. Do so by either selecting ‘Add New Action’, or simply drag & drop specific repository items from the repository to the action table in the recording.
If you’d like to connect data to your automated tests and use variables in the action table or the repository, have a look at the user guide chapter Data-Driven Testing.The User Code
You can also create your actions directly in user code. Simply drag and drop the specific repository item from the Ranorex Object Repository directly into the code editor.
In the user guide chapter Code Examples you can find further examples on how to extend modules with user specific code.Conclusion
As you can see, you can create your automated tests manually without pressing the record button at any time. This will give you more control over the actions that should be triggered.
