New Features and Improvements:

    Breakthrough Upgrades:

    • Cloud testing 
      • Seamlessly provision AWS on-demand instances right in StresStimulus for use as load agents
      • Chose a virtual machine from anywhere in the world
      • Pick your load agent machine's tech specs
      • Delete the instance right in StresStimulus when you're done
      • No additional cost for licensed StresStimulus users (only standard AWS fees apply)
    • IP Spoofing for performance testing load balancers  
    • No-Proxy Recording (aka Tunnel recording mode). Now StresStimulus supports scenario recording from client applications and native mobile apps that don't use system proxy settings and don't allow manual proxy settings 
      • Supports multiple https hosts for a single app


    More Robust Test Designer for Higher Productivity

    • Test profiles. In previous versions, you had enter test configurations such as load and VU settings each time you created a test. Now you can save your settings to a profile and use it in multiple tests.

    • Disabling transactions. Now you can disable transactions you wish to skip during test replay.

    • VU-Iteration-Random databinding method. It is similar to VU-Iter-Bound but the rows are consumed in random order instead of sequentially. 

    • Simplified databinding. Now you can specify a default databinding method for a dataset once instead of specifying it for every parameter using this dataset 

    • Easier parameter creation. When searching for requests to parameterize, not only is the request highlighted but the value is as well 

    • Test case tree object descriptions are copyable. Just select any object and hit Ctrl+C and it's description will be copied to the clipboard.

    • Support expressions with extractors in validators 
    • Verify more than one iteration at once. This may be helpful to verify the 2nd iteration when a login transaction is marked to run on the first iteration only. 
    • Troubleshoot script by comparing recorded and replayed extractor's sessions from Extractor verification tree 

    • Extractor Verification view in session comparer displays values of the extractors used in the parameters of the left and right session  

    • Now the verification tree shows not only sessions, but also the entire test case hierarchy (including transactions and pages) which simplifies locating any replay issues 
    • Now extractors and patterns can be Base64-encoded by StresStimulus if necessary 
    • More robust cookie parameterization. Now the value of the Set-Cookie object can be an expression consisting of several variables and constant strings instead of just a single variable (e.g. extractor or dataset) 

    • Compatibility with Windows language packs.
    • More robust custom patterns. Now you can customize how patterns are used to create parameters by using formatted parameters 
    • Session Image view allows to inspect individual images 

    • Image comparer.  Now you can compare recorded and replayed images which is helpful for our applications with dynamic images 

    • Status Bar in Test Case Tree displays the number and type of selected objects 

    Ease of Use Enhancements

    • Diagnostic in opening test cases.  Now error reporting will display the test case name and session number that fails to load. It can help with opening tests with multiple test cases when one of them is corrupted. 

    Broader application support 

    • Added support for SAP Netweaver. 
    • Support for client certificates authentication 

    • Support for SignalR applications 

    Simplified Scenario Recording 

    • More reliable scenario recording from non-browser clients.  Now you can specify a client's process name to record only relevant requests. 
    • Add a recording to the existing test case. Now we can expand an existing test case by recording additional user actions 
    • Mobile scenarios: Easiest certificate installation on mobile devices.
    • Recording USD scenarios:  Now StresStimulus will launch USD even if it is installed in non-default folder 

    • Automatic cash clearing when recording from USD 
    • Automatic IE cache clearing in normal mode. When a scenario cannot be recorded in private mode, now you can record it in normal mode and still avoid manual cache clearing 

    Enhanced Reporting

    • Monitoring errors during test execution. In previous versions you could analyze errors only after the test completion. Now you can monitor errors as they occur in real time 
    • Querying SQL CE Test Repository. Now you can directly query test results stored in SQL CE files to generate custom reports. Previously, custom reports were only available for SQL Server repositories.
    • Manually re-scale curves for better graph presentation. Now you can customize each curve's scale in the test result. 
    • Compare a transaction, page or iteration from the report with recorded sessions request-by-request 

    More Powerful Load Generators and Automation

    • More Control over the test workflow. Now we can limit the number of iterations for certain test cases, so they can stop before the test completion 

    • Test case bound to to load agent. Now you can assign a test case to a specific load agent  
    • Command line interface now allows to run a test with a specified a test profile. 
    • Upgraded scripting event model. Added OnAfterIteration event that is triggered on completion of each iteration. It can be useful to create custom processing after replaying a script by a VU 
    • Command line interface now allows to specify a test run name and description which will be displayed in the report 
    • Added a validator failure option to abort a VU.  

    • Simplified monitoring of load agents. Now load generator machine and security account information is determined automatically by the performance monitoring module 

    • Asynchronous requests. Previously, async requests in a scenario locked execution of a test case. Now this limitation was removed. 



    • Create parameters faster. When searching a particular value in the test case requests, the sessions(s) containing the value will be highlighted. After creating a parameter on these session(s), the value will be already highlighted in the parameterization controls 
    • Verify more than one iteration at once 
    • Text Comparer. This built-in utility compares any arbitrary texts and color-code differences. It is helpful to compare any fragments of requests or responses necessary for manual correlation and parameterization. 
    • Verify tree now supports multiple test cases. It is useful when comparing TCGroup iterations.
    • When displaying the test case tree for the first time, the property grid below is shown expanded.
    • Now you can change the folder to store the SQL CE database files from the Result storage property grid   

    • In previous versions, you could only drag and drop session objects to re-position them. Now you can drag and drop all objects.

    • In all property grids, included a link to a pop-up help window containing additional description of the property.

    • On the Extractor Tree and Test Case tree, several toolbar buttons are combined under "View Options" button to condense required screen space and simplify usage.

    • Some context menu items in the test case tree are grouped under sub-menus "Create Container" and "Insert Object" to improve usability. 
    • Prevented a common error in changing the host. Prevent changing it using the request inspector. Instead this should be done using Host Remapping feature.
    • Preventing an error with entering the recorded host and new host in the reverse order in the host remapping dialog.
    • Extractors in scriptable components. Now a scriptable component can access an extractor that eliminates the need for parsing a response. 
    • Simplified invocation of a scriptable component. Previously you need to program at which point of a test case iteration to invoke the scriptable component. Now you can automatically run the scriptable component at the end of every iteration. 
    • Support recording scenarios with Brotli compression in Chrome.
    • Reducing Test Storage Use. Increased efficiency of test storage utilization by more than 800% 

    • Simplified test storage management by merging settings for requests and response content into a single Purge Session Content property. 

    • When recording USD scenarios, the first transaction is automatically set to Login.

    • Easier certificate installation on mobile devices. In the previous versions this required proxy configuration. Now it is no longer necessary 
    • More robust cookie parameterization. Now the value of the cookie object can be not just a single variable (e.g. extractor or dataset), but also an expression consisting of  several variables and constant strings

    • Avoid false positive warning due to recorded and replayed response size discrepancy. Previously when response of a session executed on a load agent is configured to be truncated, it was flagged on Verification Tree with warning status. Now such sessions are marked with unknown status   

    • Skip proxy diagnostic option allows to disable proxy diagnostic when it interferes with Scenario recording 

    • No labels
