title: Test Frameworks
description: Set up your test framework to report its results to Test Engine, with a Mergify plugin or a JUnit XML report.
---

Test Engine builds each test's history from the results your CI runs report.
Pick your framework below: its page shows the setup, from the package to
install to the CI step that sends the results. A framework reports in one of
two ways:

- **Plugin** runs inside your tests: a Mergify package sends the results when
  the run ends and applies [quarantine](/test-engine/quarantine) in the run. On
  pull requests, it reruns new tests to catch flaky ones before they merge
  ([Prevention](/test-engine/prevention)).

- **JUnit report** is uploaded after the run: the framework writes a JUnit XML
  file, then a CI step uploads it and applies quarantine, so the job fails only
  on failures that are not quarantined. No reruns: Prevention needs a plugin.

## Other frameworks

If your framework is not listed but can write a JUnit XML report, follow the
upload steps on any JUnit report page, such as
[JUnit](/test-engine/test-frameworks/junit), and point them at your report:
`report_path` in the GitHub Actions and Buildkite steps, or the last argument
of `mergify ci junit-process`.
