Find Coverage Regression Lines

A coverage gate failed and you need the threshold, actual value, and affected file without scanning the full job output.

Command

grep -RInE 'coverage|threshold|minimum|below' artifacts logs

What changed

Nothing changes. Matching coverage-related lines are printed.

Danger

safe

When to use it

Use when a coverage check fails but the relevant message is buried in build output.

When not to use it

Do not rely on text search alone for final coverage metrics if a structured report is available.

Undo or recovery

No undo needed because this command is read-only.

Expected output

Coverage threshold and below-minimum lines from logs or reports.

Find the coverage threshold.

Coverage gates usually print the expected value and the actual value. Search for those words first.

A: Coverage failures usually say the threshold out loud.

B: Search coverage artifacts before guessing.
