To enforce a test strategy against flaky tests, apply structured guardrails that mandate deterministic testing practices like fake timers, data factories, and the avoidance of sleeps across your unit, integration, and e2e tests.

The correct test pyramid balance for backend services requires defining a strict distribution across unit, integration, and end-to-end testing layers to ensure proper coverage while maintaining fast and reliable execution.

You should mock external services versus using real integrations based on codified guidelines that determine when to isolate dependencies versus running real integrations, such as using Testcontainers, to maintain test safety.

To add deterministic tests to your pull request workflow, apply test strategy guidelines during PR reviews to ensure proper test pyramid balance and verify the usage of factory-based data and appropriate mocking.

The limitations of relying on sleeps in integration testing include introducing flakiness and unreliable execution, which is why enforcing a structured test strategy recommends using fake timers and factory-based data instead.
