            <h3>Definition</h3>

            <ul>
              <li>Pre-commit test - Any single test in a pre-commit test suite.</li>
              <li>Pre-commit test suite - A collection of pre-commit tests that have a common denominator. A test suite runs in a single Jenkins job.</li>
            </ul>

            <h3>Policies</h3>

            <h4>Pull Requests</h4>

            <ul>
              <li>A PR must pass pre-commit tests before being committed to the main Unomi repo.
                <ul>
                  <li>The relevant pre-commit test suites are automatically launched according to PR contents.</li>
                </ul>
              </li>
            </ul>

            <h4>Problems</h4>

            <h5>Breakage</h5>

            <p>Breakage is when one or more tests in a pre-commit test suite fails or is flaky (occasionally fails).</p>

            <ul>
              <li>Breakages should be fixed within 8 hours.</li>
            </ul>

            <h5>Slowness</h5>

            <p>Slowness is when the total time to run a pre-commit suite exceeds 30 minutes*, including the time the job spends in the Jenkins queue.</p>

            <ul>
              <li>Slowness should be fixed within 24 hours.</li>
            </ul>

            <h4>Problem Resolution</h4>

            <p>For any problem, the options are, one of:</p>

            <ul>
              <li>Roll back the culprit PR.</li>
              <li>Roll out a fix within 24 hours.</li>
              <li>Disable the slow test or feature temporarily (make sure there is a tracking issue to re-enable it).</li>
            </ul>
