# 2025-02-02

This release of Cover enhances flexibility, security, and reliability with several key improvements:

* **Ant Build System Support**: Cover CLI now supports Ant projects. [Learn more](https://docs.diffblue.com/features/cover-cli/project-configuration/configuring-cover-to-work-with-your-projects-build-system/getting-started-with-ant-projects).
* **Excluding Trivial Methods**: A new CLI option allows users to exclude trivial methods from test generation.
* **SSO Integration for Cover Reports**: Enterprise users can now integrate with existing SSO providers for authentication, eliminating the need for a proxy server. [Learn more](https://docs.diffblue.com/features/cover-reports/cover-reports-administrator/sso-with-cover-reports).
* **Spring Controller Improvements**: Test generation now produces more concise annotations and better handles `@ControllerAdvice` classes.
* **Bug Fixes**: This release resolves issues related to:
  * Gradle compilation parsing
  * Automatic Spotless formatting
  * Module path errors in multi-module projects

## Important Notices

### **Test Review Plugin: Enabled by Default (from 2025.03.01)**

Starting with the next release, the **Test Review** feature in the IntelliJ Plugin will be **enabled by default**.

* Tests must be **accepted manually** before appearing in your codebase.
* You can edit or reject tests as needed.
* If you haven’t tried it yet, enable it now from the IntelliJ Plugin's **Diffblue Settings menu**.

[Read the Test Review documentation](https://docs.diffblue.com/features/cover-plugin/writing-tests/test-review).

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

As of this release, the following CLI options have been **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

* CLI: Cover now includes an `--exclude-trivial-methods` flag for CLI users to opt-out of testing trivial methods like getters and setters. This provides more control over test generation, helping avoid unnecessary tests for simple methods. \[Ref: TG-22709]
* CLI: Build system customization options (e.g., `--build-system-configuration`) are now deprecated. Configure Cover using a `DiffblueBuild.yaml` file for improved build system integration. \[Ref: TG-22640]
* CLI: Cover now supports projects which use Ant build systems. \[Ref: TG-22631]
* CLI: Diffblue now offers Ant build system tasks via our public Maven repository, simplifying integration for Ant projects by enabling the use of a Maven dependency instead of specifying an absolute JAR file path. \[Ref: TG-22611]
* CLI: Cover's environment and test creation summaries in log files now include the project module name, improving clarity and searchability. \[Ref: TG-22581]
* Cover now generates `@MethodsUnderTests` annotations more concisely using available imports, enhancing test code readability and simplifying maintainability. \[Ref: TG-22558]
* Reports: Enterprise users can now integrate their existing SSO providers, such as Keycloak, for secure authentication and role-based access control. This enhances data security, streamlines user management, and ensures compliance with enterprise policies. \[Ref: TG-22509]
* Cover now more accurately identifies essential mock dependencies in Spring applications, resulting in tests with reduced unused mocking and improved readability. \[Ref: TG-22411]
* Cover now generates better tests for Spring Controllers. Cover considers `@ControllerAdvice` classes when writing tests, leading to more complete and accurate results for applications using Spring's exception handling. \[Ref: TG-20569]

## Resolved Issues

* Resolved an issue which caused Cover to incorrectly parse compilation failures on Gradle projects when using Java 17.0.14+ and newer versions. \[Ref: TG-22677]
* Resolved an issue where Cover did not automatically apply Spotless, when available, for test code formatting in Gradle builds. \[Ref: TG-22658]
* Resolved an issue where Cover failed to run on certain multi-module Gradle projects due to module path errors. This caused `Failed to run a simple example test` (E011) warnings during execution. \[Ref: TG-22592]

## 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]
