There was a problem hiding this comment.
The new env still needs to be registered in the central registry :)

What does this PR do?
Add
DD_TEST_TIA_KEEP_COV_CONFIGsupport to Jest TIA coverage handling and refines behavior based on whether coverage was enabled by dd-trace or by the user.Motivation
Users need a way to preserve their Jest coverage configuration during TIA runs, while still allowing dd-trace to optimize coverage work when coverage was only enabled internally.
Additional Notes
Add
DD_TEST_TIA_KEEP_COV_CONFIGto supported configurations.Behavior now:
collectCoverage+passWithNoTests.coverageReporters: ['none']and skip_addUntestedFilesonly when the user had not already configuredjestto run with code coverage.
