Test Coverage¶

Find under-tested code and automatically add focused tests.

Test Coverage Detector identifies code paths with no or minimal test coverage by running coverage tools (when available) and analyzing recent changes for missing tests. Chain it to Create PR from Issue for a fully autonomous detect-and-fix loop. Most runs end with noop.

Quick install¶

Detector only¶

Install the detector alone if you want to review test coverage reports before acting.

mkdir -p .github/workflows && curl -fsSL \
  https://raw.githubusercontent.com/elastic/ai-github-actions/v0/gh-agent-workflows/test-coverage-detector/example.yml \
  -o .github/workflows/test-coverage-detector.yml

Chained (detector + fixer)¶

Install the chained example for autonomous detection and test improvement.

mkdir -p .github/workflows && curl -fsSL \
  https://raw.githubusercontent.com/elastic/ai-github-actions/v0/gh-agent-workflows/test-coverage-detector/example-chained.yml \
  -o .github/workflows/test-coverage-detect-and-fix.yml

Test Coverage Detector¶

Identifies code paths with no or minimal test coverage by running coverage tools (when available) and analyzing recent changes for missing tests. Files a report with specific, actionable recommendations for each gap — including the user scenario and suggested test approach.

Trigger¶

Event	Schedule
`schedule`	Weekdays
`workflow_dispatch`	Manual

Inputs¶

Input	Description	Default
`additional-instructions`	Repo-specific instructions appended to the agent prompt	`""`
`setup-commands`	Shell commands run before the agent starts	`""`

Safe outputs¶

create-issue — file a test coverage report (max 1, auto-closes older reports)
