Migrate org.eclipse.ui.tests.navigator from JUnit 4 to JUnit 5
This commit migrates the entire org.eclipse.ui.tests.navigator test suite from JUnit 4 to JUnit 5, modernizing the test infrastructure and improving test reliability with better resource management. JUnit 5 Migration Changes: - Updated all test annotations (@before → @beforeeach, @after → @AfterEach, @ignore → @disabled) - Migrated static imports from org.junit.Assert to org.junit.jupiter.api.Assertions - Replaced CloseTestWindowsRule (JUnit 4) with inline window management: - Added @AfterEach tearDown() method - Inlined window listener and shell tracking logic - This avoids needing to add JUnit 5 dependencies to the test harness bundle - Fixed all assertion parameter orders from JUnit 4 style (message-first) to JUnit 5 style (message-last): * assertEquals(message, expected, actual) → assertEquals(expected, actual, message) * assertTrue(message, condition) → assertTrue(condition, message) * assertFalse(message, condition) → assertFalse(condition, message) Test Infrastructure Improvements: manages UI test windows and shell cleanup, replacing the previous JUnit 4 rule-based approach - Updated GoBackForwardsTest to use @RegisterExtension with the new extension - Ensures better test isolation by cleaning up leaked shells between tests Benefits: - Uses modern JUnit 5 features and best practices - Improved resource cleanup prevents test interference - Consistent with Eclipse platform's migration to JUnit 5 - Better test isolation and reliability 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
