To enforce test-driven development for Spring Boot, apply a structured workflow that requires writing failing tests before implementation. This approach eliminates untested code by guiding you through creating the test first, implementing the logic, and verifying coverage thresholds.

Achieving 80% test coverage in Spring Boot requires combining JUnit 5 for test execution and JaCoCo for coverage measurement. You must write multi-layer tests across unit, web, and integration layers to satisfy the combined coverage threshold.

Yes, Testcontainers works with Spring Boot integration testing to create production-like environments for data access layers. It enables you to write failing persistence tests first, verifying database interactions before implementing the actual bug fix or feature logic.

The best way to write web layer tests for Spring Boot services is using MockMvc alongside Mockito. This combination isolates the web layer by mocking service dependencies, ensuring controllers are tested thoroughly without requiring full application context.

Yes, you can use Mockito for unit testing Spring Boot security logic. It allows you to mock security dependencies and isolate specific security components, ensuring your security implementations meet the required 80% combined test coverage threshold.

Spring Boot refactoring breaks test suites when they are brittle and lack sufficient coverage. Applying a structured test-driven development workflow prevents this by ensuring multi-layer tests validate the behavior before and after code changes, maintaining 80%+ coverage.
