An optimal test suite ratio balances unit, integration, and E2E tests based on the testing pyramid and honeycomb models. This strategy guides you in allocating tests to ensure critical paths are covered while spending development time efficiently on valuable, maintainable tests.

Unit tests are best suited for isolated logic scenarios, while integration tests focus on dependency management. This strategy details best practices for unit test isolation and integration test dependency management to help you identify exactly what to test at each level.

End-to-end tests should be reserved for critical user journeys within your application. This strategy guides you in identifying these essential paths so you can implement E2E tests efficiently without unnecessarily slowing down your overall test suite execution.

Planning a test suite for an authentication module involves defining the right mix of unit, integration, and E2E tests. You apply testing pyramid guidance to cover critical security paths and ensure test effectiveness through mutation testing and meaningful coverage targets.

This testing strategy works for both new and existing software projects by helping you define and implement an effective testing approach. It ensures your software remains robust, reliable, and maintainable by guiding you on what, how, and how much to test.
