Detect flaky tests by running your test suite multiple times.
DeFlaky wraps your existing test command, runs it N times, and identifies which tests are flaky, always-failing, or stable. It calculates a FlakeScore and optionally pushes results to the DeFlaky Dashboard.
Works with Playwright, Selenium, Cypress, Jest, Pytest, Mocha and any framework that outputs JUnit XML or JSON reports.
npm install -g deflaky

npx deflaky --help
# Run your test suite 5 times and detect flaky tests
deflaky -c "npx playwright test" -r 5
# Run 10 times with verbose output
deflaky -c "npx jest --ci" -r 10 --verbose
# Push results to DeFlaky dashboard
deflaky -c "npx playwright test" -r 5 --push --token YOUR_TOKEN
# Fail CI if FlakeScore drops below 90%
deflaky -c "npx pytest" -r 3 --fail-threshold 90
