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. Test Improver adds focused tests that validate real behavior and cleans up redundant tests. Most runs of either workflow 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

Full loop (detector + fixer)¶

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

Example workflow¶

name: Test Coverage Detector
on:
  schedule:
    - cron: "0 10 * * 1-5"
  workflow_dispatch:

permissions:
  actions: read
  contents: read
  issues: write
  pull-requests: read

Test Improver (fixer)¶

Identifies code paths with no or minimal test coverage, adds focused tests that validate real behavior, and removes or consolidates clearly redundant tests. Only opens a PR for changes that would catch actual regressions — not trivial getters or incidental coverage.

Trigger¶

Event	Schedule
`schedule`	Weekly
`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-pull-request — open a PR with test improvements
