# Java testing strategies Apply proven testing strategies (RIGHT-BICEP, A-TRIP, CORRECT) to design and verify Java unit tests. **What is covered in this Skill?** - **RIGHT-BICEP**: Key questions to guide test creation — Right results, Boundary conditions, Inverse relationships, Cross-checks, Error conditions, Performance - **A-TRIP**: Characteristics of good tests — Automatic, Thorough, Repeatable, Independent, Professional - **CORRECT**: Boundary condition verification — Conformance, Ordering, Range, Reference, Existence, Cardinality, Time ## Constraints Before applying any test strategy changes, ensure the project compiles. If compilation fails, stop immediately — do not proceed until resolved. After applying improvements, run full verification. - **MANDATORY**: Run `./mvnw compile` or `mvn compile` before applying any change - **SAFETY**: If compilation fails, stop immediately and do not proceed — compilation failure is a blocking condition - **VERIFY**: Run `./mvnw clean verify` or `mvn clean verify` after applying improvements - **BEFORE APPLYING**: Read the reference for detailed examples, good/bad patterns, and constraints ## When to use this skill - Review Java code for testing strategies - Apply RIGHT-BICEP testing strategies in Java code - Apply A-TRIP testing strategies in Java code - Apply CORRECT boundary condition verification in Java code ## Reference For detailed guidance, examples, and constraints, see [references/130-java-testing-strategies.md](references/130-java-testing-strategies.md).
