📝 Walkthrough

Walkthrough

Test teardown now clears persisted repository data in NetworkModificationUnitTest and NodeActivityServiceTest. NodeActivityServiceTest also uses @AfterEach for automatic cleanup.

Changes

Test repository cleanup

Layer / File(s)	Summary
Persisted test data teardown src/test/java/org/gridsuite/study/server/NetworkModificationUnitTest.java, src/test/java/org/gridsuite/study/server/nodeactivity/NodeActivityServiceTest.java	Both test classes delete persisted entities after each test. NodeActivityServiceTest adds the @AfterEach import and annotation.

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to 50923

A failed test can leave database state behind and make later tests order-dependent. Ensure teardown cleanup always runs before merging.

In `@src/test/java/org/gridsuite/study/server/NetworkModificationUnitTest.java`:
- Around line 463-468: Move the six repository cleanup
calls—rootNetworkNodeInfoRepository.deleteAll(),
rootNodeInfoRepository.deleteAll(),
networkModificationNodeInfoRepository.deleteAll(), nodeRepository.deleteAll(),
rootNetworkRepository.deleteAll(), and studyRepository.deleteAll()—into the
test’s finally block so they execute even when assertNull throws AssertionError;
keep the existing output cleanup there as well.
