This release provides a range of updates and enhancements. See the full Release Notes below for details.


  • Reports: Cover Reports will no longer display data for code excluded through a JaCoCo configuration. [Ref: TG-20445]

  • Cover: Cover now attempts to find methods in the tested class as Predicate/Function parameters for the tested method. If none are found, it reverts to using mocked values. [Ref: TG-20318]

Resolved Issues

  • CLI: Resolved an issue which caused Cover CLI to report E014 - No build system found when using --classpath without Maven or Gradle present. [Ref: TG-20674]

  • CLI: Resolved an issue which under some circumstances caused Cover CLI to display the incorrect upload URL when uploading reports bundles. [Ref: TG-20439]

Known Issues

  • Plugin: Cover Plugin incorrectly gives the option to write tests for a test file using the menu option, while in the IDE editor. [Ref: TG-17163]

  • Cover: Cover may produce tests for JUnit 4.10 and lower that do not compile due to the use of assertNotEquals. [Ref: TG-17605]

  • Cover: Diffblue Cover supports Open JDK and Oracle JDK; results with other JDKs may differ due to the variability in their implementations of Java. [Ref: TG-19345]

  • Cover: Cover may encounter an F009: Internal error while writing tests using Mockito 5. To avoid this issue use a version of Mockito earlier than 5. [Ref: TG-19610]
