Spring Boot TDD Workflow

TDD guidance for Spring Boot services with 80%+ coverage (unit + integration).

When to Use

• New features or endpoints
• Bug fixes or refactors
• Adding data access logic or security rules
• Writing MockMvc tests for controller layer validation and error response shapes
• Setting up Testcontainers for integration tests against a real PostgreSQL database
• Enforcing 80%+ line coverage with JaCoCo in a Maven or Gradle build pipeline
• Adding parameterized tests to cover multiple input variants without duplicating test code
