The testing pyramid is a model that guides the ideal distribution of unit, integration, and E2E tests to ensure a stable test suite. It emphasizes having a large base of fast, isolated unit tests to build reliable software quality methodologies.

You structure unit tests using the AAA pattern by dividing tests into Arrange, Act, and Assert sections. This pattern helps developers write clear, self-checking tests by explicitly separating setup, execution, and verification steps.

Use mocking strategies in integration testing to isolate external dependencies and ensure tests are repeatable. You can apply mocks, stubs, spies, and fakes to simulate behaviors without executing real external service calls.

Best practices for test organization involve implementing effective naming conventions and logical grouping for test suites. This ensures your unit and integration tests remain maintainable, fast, isolated, and self-checking across the project.

No specific testing framework is required. The testing patterns focus on universal principles like the testing pyramid, AAA structure, and mocking techniques that you can apply across any development environment to establish consistent methodologies.
