A good testing strategy prioritizes correct tests over chasing 100% coverage. It applies the test pyramid to validate core business logic, using unit, integration, and E2E tests for rapid and reliable execution.

Apply unit testing, integration testing, and E2E testing by starting with core business logic and progressively adding broader tests. This resilient strategy uses mocks, spies, and real-world examples to validate behavior across environments.

Use mocking and spies in unit and integration tests to isolate components and validate interactions. This strategy incorporates practical examples and tooling guidance to ensure tests remain fast, reliable, and focused on core business logic.

Test-driven development works effectively without 100% coverage by focusing on correct tests and prioritizing core business logic. This strategy designs fast, low-cost tests across unit, integration, and E2E scenarios to increase code reliability.

The best way to set up a test environment for rapid execution is to apply the test pyramid and use tooling guidance. This strategy provides environment setup, practical tips, and checklists to enable fast, reliable validation of core business logic.
