# 2025-03-01

This release of Cover focuses on improving test generation and plugin user experience:

* **Improved Enum Handling**: Cover now writes tests with better branch coverage when comparing enums by name.
* **Conflict Detection & Remediation**: Cover identifies and warns about potential conflicts between PowerMock and Mockito artefacts, offering remediation advice to ensure optimal test generation.
* **Enhanced Test Review**: The Test Review feature is enabled by default, allowing for manual acceptance of generated tests before integration into your codebase. Navigating tests for review is simplified with a list of method-under-test.
* **IntelliJ IDEA Support Expansion**: Cover now supports IntelliJ IDEA Community Edition 2025.1 EAP.

## Important Notices

### **CLI: Deprecation of Build System Customization Options**

As of the `2025.02.02` release, the following CLI options have been marked as **deprecated**:

* `--build-system-configuration`
* `--ignore-stylechecks`
* `--jacoco-command-diffblue`
* `--jacoco-command-manual`
* `--jacoco-xml-test-report`
* `--preflight-test-command`
* `--preflight-test-timeout`
* `--validation-timeout`
* `--validation-command`

Migrating to a `DiffblueBuild.yaml` file is recommended for build system integration. See the [configuration guide](https://docs.diffblue.com/features/cover-cli/project-configuration/configuring-cover-to-work-with-your-projects-build-system/) for more details.

## Enhancements

* Plugin: Cover now supports IntelliJ IDEA Community Edition 2025.1 and IntelliJ IDEA Ultimate 2025.1 EAP. \[Ref: TG-22574]
* Plugin: Cover now displays a list of test methods in the Test Review panel. This allows for easier navigation through tests requiring review, grouped by method-under-test. The list will not appear if descriptive test names are disabled. \[Ref: TG-22376]
* Reports: Tests tagged with `MaintainedByDiffblue`, in any test files, now count towards the 'Diffblue coverage' statistic shown in Cover Reports. \[Ref: TG-21447]
* Plugin: Cover's Test Review feature is now enabled by default. Tests must be accepted manually before appearing in your codebase. Test Review can be disabled via the plugin settings dialog. \[Ref: TG-21297]
* CLI & Plugin: Diffblue Cover now writes tests with improved branch coverage for code comparing enums by name. \[Ref: TG-20568]

## Resolved Issues

* Resolved an issue which caused Cover to recommend incorrect `cover-annotations` dependency scope: it now recommends `provided` (Maven) or `compileOnly` (Gradle). \[Ref: TG-22749]
* CLI & Plugin: Cover now provides a warning (`E154`) and remediation advice if PowerMock and Mockito artefacts conflict. Conflicting artefacts can cause Cover to write fewer tests. \[Ref: TG-21209]

## Known Issues

* Plugin: Cover incorrectly provides a menu option to write tests for a test file. \[Ref: TG-17163]
* 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]
* Reports: Cover only counts Java code towards the total line count metrics. Kotlin code is not currently included. \[Ref: TG-22088]
* Reports: Total lines of code metric can incorrectly count a multi-line comment at the end of a line of code, resulting in fewer than expected lines counted. \[Ref: TG-22089]
* Reports: Following an upgrade, the 'Total Lines of Code' card may show 0 until a new reports bundle has been uploaded. \[Ref: TG-22094]
* In some circumstances, Cover may write more simplistic tests with less meaningful assertions when Spring Boot dependency injection is disabled. \[Ref: TG-22102]
* In some circumstances, Cover will still write Spring Boot tests when Spring Boot dependency injection is disabled. \[Ref: TG-22103]
* Cover may write failing TestNG tests when Spring Boot dependency injection is disabled. \[Ref: TG-22107]
* Plugin: On some displays, the Test Review subsection title "Tests for review" can be malformed. \[Ref: TG-22805]
