kubernetes-sigs Skill: Split Large Test Files for New Features
Flag: A PR adds substantial test coverage for a new feature to an already large test file (e.g., scheduler_test.go, workload_controller_test.go).
When to split — all three conditions should hold:
- The feature has a distinct name that maps cleanly to a file suffix (e.g.,
_tas,_afs,_concurrentadmission). - The new tests require feature-specific setup — enabling a feature gate, constructing feature-specific resources — that is unrelated to the base test suite's setup.
- The new tests would add a significant block of lines (roughly 150+) to a file that is already large.
Ask: Extract the feature's tests into <package>_<feature>_test.go. Precedent: scheduler_tas_test.go, scheduler_afs_test.go. This keeps the base file navigable and makes feature-specific scenarios easy to find and extend.
