Test Runner for Java ignores @BeforeAll annotations on test classes

[demonfiddler]

Symptom: JUnit 5 test methods in a test class with an @BeforeAll method are correctly initialised and pass when run with gradlew test but do not get correctly initialised and fail when the test method is run individually in the VSCode IDE.

System: Windows 10, VSCode 1.96.3, Gradle 8.12, Spring Boot 3.4.1, Java 21.04, JUnit 5.11.4

Hi @demonfiddler, I'm an AI Support assistant here to help with your issue. While the team reviews your request, I wanted to provide some possible tips and documentation that might help you in the meantime.

Suggestions:

• Ensure your @BeforeAll method is static, or annotate the test class with @TestInstance(Lifecycle.PER_CLASS) to allow non-static @BeforeAll methods. See JUnit 5 docs:

  • https://junit.org/junit5/docs/current/user-guide/#writing-tests-annotations

• Update the Java Test Runner extension to the latest version, which includes fixes for @BeforeAll initialization when running individual tests.

Other references with high confidence:
