  • MAJOR version when you make incompatible API changes,
  • MINOR version when you add functionality in a backwards-compatible manner, and
  • PATCH version when you make backwards compatible bug fixes.

29.1.2

  • [fix] teamscale-maven-plugin: Partition was not correctly provided to the impacted test engine

29.0.0

  • [fix] Fixed the prefix extraction pattern and the partition pattern for Artifactory in the agent's documentation
  • [fix/breaking change] teamscale-client, teamscale-gradle-plugin, teamscale-maven-plugin, teamscale-jacoco-agent: Teamscale 8.0 introduced the concept of execution units. To distinguish them from normal, singular test executions, the -test-exection- and -execution-unit- uniform path prefixes were introduced. This broke gradle and maven test runner plugins because the actual test paths and Teamscale's uniform paths did not match anymore. To prevent this, testName is now exposed by the teamscale client and used by the plugins which corresponds to the uniform path without the prefixes. If you're using the client, or listen to the /testrun/start API from the Teamscale JaCoCo agent, this is a breaking change. You now need to use testName in your runner, not the uniformPath.

28.0.0

  • [breaking change] removed support for JavaWS
  • [fix] Fixed git.properties detection when directories are on the classpath

27.0.2

  • [fix] Updated dependencies (Fixes #225, CVE-2022-42889)

  • [fix] teamscale-gradle-plugin: Failed to upload JUnit reports
  • [breaking change] teamscale-gradle-plugin: Setting the destination within test.teamscale.reports.jacoco/junit transparently sets the report destination in the corresponding jacoco/junit plugins
  • [breaking change] teamscale-gradle-plugin: TestwiseCoverageReportTask no longer clears the parent folder of the written testwise coverage report

26.0.2

  • [fix] Testwise coverage conversion was slow when many .exec files are included.

26.0.1

  • [fix] The agent could not be started with the debug=true command line option

26.0.0

  • [fix] impacted-test-engine: Handle tests with trailing whitespaces correctly
  • [breaking] impacted-test-engine: Now requires Teamscale 8.0 as minimum version

25.0.0

  • [breaking] Find git.properties files recursively in folders, all types of archive files (jar, war, ear, aar, ...) and arbitrary depth. This was only possible for nested jar and war files and up to nesting depth 1. If you'd like to disable recursive search, e.g. due to performance issues, please use search-git-properties-recursively=false.
    Note: This is not actually a breaking change but if you profile large projects and don't use the multi-project upload, you might want to disable recursive search.

24.1.1

  • [fix] Maven plugin for TIA: sometimes the agent was not attached to a Spring Boot application during integration tests

If the specified output file is named testwise_coverage.json the actually written file will be called testwise_coverage-1.json for the first 5000 tests. For uploading multiple files use an upload session.
