Regression Pack Curator

Curate and maintain regression test suites by selecting, prioritizing, and pruning tests.

When to Use

• When updating regression suites after feature changes
• When selecting regression tests for a release
• When identifying obsolete or redundant tests to remove
• When optimizing regression execution time

Procedure

1. Assess the current regression suite:
   • Total tests and execution time
   • Coverage by feature area
   • Test age and last modification date
   • Pass/fail history and flakiness
2. Based on recent changes, determine:
   • Tests to add: New scenarios for changed functionality
   • Tests to update: Existing tests affected by changes
   • Tests to remove: Obsolete tests for removed features
   • Tests to prioritize: High-risk areas get earlier execution
3. Apply curation rules:
   • Remove duplicate coverage (tests that verify the same thing)
