Pull request overview
This PR continues the HBASE-30138 effort to migrate hbase-server tests from JUnit4 to JUnit5, updating lifecycle annotations, assertions, categories/tags, and converting JUnit4 parameterized/rule patterns to their JUnit5 equivalents (including HBase’s @HBaseParameterizedTestTemplate).
Changes:
- Migrated numerous RegionServer-related tests from JUnit4 (
@Before/@After/@Category/@RunWith, Rules) to JUnit5 (@BeforeEach/@AfterEach/@Tag, extensions,TestInfo). - Converted JUnit4 parameterized tests to JUnit5
@TestTemplate+@HBaseParameterizedTestTemplatewithStream<Arguments> parameters(). - Updated assertions to JUnit5
org.junit.jupiter.api.Assertionsstyles and modern exception assertions (assertThrows).
