What is the recommended code coverage target?

The workflow is optimized to help developers reach and maintain a minimum of 80% code coverage across unit and integration tests.

Does it support both Maven and Gradle?

Yes, the skill includes build commands and configuration snippets for both Maven (mvn verify) and Gradle (./gradlew test).

What testing tools does this skill support?

It provides patterns and guidance for JUnit 5, Mockito, MockMvc, AssertJ, Testcontainers (for Postgres/Redis), and JaCoCo for coverage reporting.

Can I use this for existing Spring Boot projects?

Yes, it is specifically designed for adding new features, fixing bugs, or refactoring existing codebases while ensuring regression safety.

How does it handle integration testing?

The skill utilizes Testcontainers to spin up isolated, throwaway database instances that mirror your production environment, ensuring tests are realistic and reliable.
