A flaky test is the one that returns unpredictable results without any apparent changes to the tested code. It's a test that can be green nine times out of ten only to randomly fail on the tenth attempt. Because of that unpredictable nature, flaky tests are difficult to debug, which makes them difficult to fix.

What is flakiness in software testing?
A flaky test is a software test that yields both passing and failing results despite zero changes to the code or test. In other words, flaky tests fail to produce the same outcome with each individual test run.

1. Break the tests down for increased readability.
2. Get the tests to fail by using sleep().
3. Simplify assertions to assert only data.

What is the cause of flaky test?
Flaky tests can be caused by various factors, including environmental issues, timing and synchronization problems, test dependencies, inconsistent test data, and non-deterministic application behavior.
