Type: Bug
When using @Nested test classes in JUnit 5 (with Spring Boot @DataJpaTest / Testcontainers), the extension fails to render CodeLens buttons for inner classes and freezes when running individual nested test methods from the Test Explorer.
Environment
- OS: macOS (zsh)
- VS Code Extension: Test Runner for Java (
vscjava.vscode-java-test)
- Framework: Spring Boot + JUnit 5 + Testcontainers
Steps to Reproduce
- Create a main test class annotated with
@DataJpaTest and @Import(TestcontainersConfiguration.class).
- Create inner classes annotated with
@Nested and @DisplayName.
- Open the file in VS Code.
Expected Behavior
- CodeLens ("Run | Debug") should appear above
@Nested inner classes and their @Test methods.
- Running a single
@Test method from inside a @Nested class via the Test Explorer panel should execute cleanly.
Actual Behavior
- CodeLens buttons are missing above
@Nested inner classes.
- Triggering a single test method inside
@Nested from the Test Explorer hangs/freezes indefinitely (likely due to nested class $ delimiter escaping issues in macOS zsh or context inheritance failures).
Workaround attempted
Adding @NestedTestConfiguration(INHERIT) and setting spring.test.nested.class.execution=INHERIT did not prevent the runner from hanging when selecting individual nested methods.
