Test Stress Tester

This skill provides a programmatic way to run tests repeatedly to catch flakiness, race conditions, or intermittent failures that only surface in CI.

When to use

• When a test passes locally but fails in CI.
• When you suspect a race condition in asynchronous code.
• When you want to verify the stability of a new feature before merging.

Scripts

run-repeatedly

Runs a vitest test file a specified number of times and reports the failure rate.

Command:

./.agent/skills/test-stress-tester/scripts/run-repeatedly.sh <test-file> <iterations>

Parameters:

• <test-file>: Path to the vitest test file.
• <iterations>: Number of times to run the test (default: 5).

Examples

Stress testing a component

./.agent/skills/test-stress-tester/scripts/run-repeatedly.sh src/components/AdDetail.test.tsx 10

Tips

• Keep iterations reasonable (5-10) for UI tests.
• For backend/logic tests, you can go higher (50+).
• Check the stress-test.log in the skill folder for detailed failure logs if any.
