Test Migration

Update and adapt tests to work with the migrated codebase.

Migration Checklist

Test Framework Updates

• Update test runner configuration for new framework version
• Migrate deprecated test lifecycle hooks and annotations
• Replace removed assertion methods with new equivalents
• Verify test discovery and execution still works correctly

Mock & Stub Adaptation

• Update mock library calls to match new API signatures
• Replace deprecated mocking patterns with current idioms
• Verify mock setup and teardown follows new conventions
• Check that spy and capture APIs are updated

Assertion Updates

• Replace deprecated assertion syntax with modern equivalents
• Update custom matchers to comply with new interfaces
• Verify error message formatting in assertion failures
• Check for changed equality semantics in assertions

Coverage Preservation

• Compare test coverage before and after migration
• Identify tests that were skipped or broken by migration
• Ensure critical paths retain full test coverage
• Add missing tests for newly introduced migration code

Output Format

Report findings with risk ratings:

Risk	Description
Critical	Tests silently pass but no longer verify behavior
High	Significant test coverage lost, gaps in verification
Medium	Some tests need updating but coverage is adequate
Low	Minor test syntax changes, coverage is maintained
