Enable or disable suites per project
Open Project Settings > Test Suites. Each suite shows Active or Inactive status and the count of tests inside. Click a suite to toggle it. Disabled suites are skipped on every scan for this project.
Run only certain suites in one scan
When you start a Test Run, the Test Suites dropdown lets you pick All Tests, Essential Only (a curated subset of roughly 67 tests for quick health checks), an individual suite, or Custom Tests Only.
