description: Monitor, detect, and manage unreliable tests across your repositories.

Test Insights helps you manage test reliability across the full lifecycle.
It catches flaky tests on pull requests before they merge, surfaces unhealthy
tests across your repositories, and lets you quarantine problematic tests so
they don't block your CI pipeline.

## How it works

Test Insights is organized into three phases that follow the natural lifecycle
of a test reliability problem:

1. **[Prevention](/test-insights/prevention)**: Catch flaky and broken tests
   on pull requests before they reach your codebase. Mergify reruns tests on
   PRs to detect inconsistent behavior early.

2. **[Detection](/test-insights/detection)**: Identify and prioritize
   unhealthy tests across your repositories. See which tests are flaky or
   broken, and focus on the ones with the most impact.

3. **[Mitigation](/test-insights/mitigation)**: Quarantine problematic tests
   to unblock CI without removing them. Tests keep running, but their failures
   no longer block merges.

## Key concepts

- **Flaky test**: A test that produces different results on the same commit.
  For example, passing on one run and failing on the next with identical code.

- **Broken test**: A test that fails consistently, with recent runs weighted
  more heavily.

- **Health status**: A test's reliability classification: healthy, flaky, or
  broken. Based on results from multiple CI runs.

- **Confidence**: How much data is available to assess a test's health. Low
  confidence means the status could still change significantly as more runs
  are collected.

- **Quarantine**: Isolating a test so its failures are ignored for merge
  decisions. The test still runs and results are still collected, preserving
  full visibility.

## Setup

Test Insights is powered by the same CI integration as
[CI Insights](/ci-insights). To get started, configure your CI system and test
framework:

- [GitHub Actions setup](/ci-insights/setup/github-actions)
- [Jenkins setup](/ci-insights/setup/jenkins)
- [Test framework configuration](/ci-insights#test-framework-configuration)
