Fix a flaky test that passes and fails at random
A flaky test passes and fails with no code change. This prompt looks for the usual causes, such as async timing, shared state and dates, and rewrites the test so it is reliable without adding sleeps or retries.
Act as a test reliability expert. This test fails about [HOW OFTEN, e.g. 1 in 5 runs] with no code change. Test code: [PASTE THE TEST] Code under test: [PASTE] Failure output: [PASTE A FAILING RUN] Find the source of the flakiness: timing and async waits, shared state between tests, test order, random data, dates and timezones, network calls or leftover files. Explain the cause in plain words, then rewrite the test so it is deterministic. Do not fix it by adding sleeps or retries.
If you can, run the test 20 times in a loop and paste two different failures. Patterns between them point to the cause.
