AI Assistant

A new AI Assistant is available in dotTEST. Users can ask questions about the product in natural language and the AI Assistant will answer based on documentation and integration with a pre-configured LLM provider. New and existing users can learn the product and get help more efficiently using the AI Assistant. Access the AI Assistant by navigating in the desktop to Parasoft > Show View > AI Assistant. See The AI Assistant for more information.

Code Coverage Enhancements

• dotTEST introduces a new dedicated coverage agent UI, which allows you to collect coverage data from managed code during manual or automated functional tests. This UI is launched by running the agent client in the console without parameters, and allows you to collect coverage for standalone (desktop) applications and web applications. For details, see Application Coverage.
• The coverage_wizard.exe application has been removed.
• A .yaml OpenAPI specification endpoint has been added to the coverage agent that documents the REST API exposed by the coverage agent.

Static Analysis Enhancements

• You can now install an external Roslyn analyzer that includes custom rules, and use these rules in your analysis. You can also create a custom analyzer and use it with dotTEST. See -installAnalyzer.
• The suppression mechanism has been extended to allow suppressing similar violations in different versions of dotTEST.

Support for .NET 9

Support for .NET 9 has been added. See Supported Frameworks.

Support for C# 13

VSCode Extension Enhancements

• Violations are now saved in a file when applying the Fix with AI option in Problems View.
• Authentication with Azure Pipelines no longer requires additional extensions to be installed.
• You can now import the analysis results of a project named differently than the current workspace.
• You can now import violations from GitLab to VSCode using a personal token with any role.
• It is now possible to select an AI model when working with Copilot Chat using the @parasoft participant.

Additional Updates

• The shipped JRE has been upgraded to version 21.0.7+6.
• dotTEST now supports groups of rule equivalents. When one of these rules is suppressed at the point of violation, the suppression is automatically applied to all equivalent rules in the group. See Automatically suppress violations of equivalent rules.
• dotTEST can now be configured to be FIPS 140-3 compliant.
• The severity specified in a <rule-id>-<severity> pattern (e.g., BD.PB.VOVR-3) used in a suppression comment or suppression record is now taken into account when suppressing violations. A violation is suppressed if its severity matches or is lower than the one specified in the suppression pattern. If the rule's severity has increased, existing suppressions will no longer apply.
• You can now customize any of the intermediate XSL transformation files used to generate reports in all available formats as an alternative to building a custom XSL transformation from scratch. See Customizing XSL Files Used to Generate Reports.
• Parameters used to configure dotTEST for test execution are now always included in XML reports.
• Settings can now be imported from a remote location. See Importing Preferences.
• Rule documentation is now distributed as a .zip file. You can specify the path to a .zip file containing the documentation. See Specifying the Rule Documentation Path. 
• The dotTEST installation process is now faster and more efficient.
• dottestcov now requires .NET 9 runtime.
