Description
java-junit is an agent skill from the github/awesome-copilot collection that gives best practices for unit testing Java projects with JUnit 5, covering both standard and data-driven tests. It sets out the project layout for Maven or Gradle, placing test code in src/test/java and including the junit-jupiter-api, junit-jupiter-engine and junit-jupiter-params dependencies, with the parameterized tests in the params package. Test structure follows the Arrange-Act-Assert pattern, and the lifecycle annotations, BeforeEach, AfterEach, BeforeAll and AfterAll, control setup and teardown. Naming conventions use DisplayName so that test reports read as plain sentences. The skill is useful for Java teams writing tests for a new project or tidying an existing suite, and for anyone who wants parameterized tests that run one test over many inputs. Tests should check real behavior, with assertions that would fail if the code were wrong, and the suite should run quickly enough that developers run it often. The skill is installed with the skills CLI from the github/awesome-copilot repository. Its skills.sh page showed about 11.5K installs and passing results from three security audits at the time of the scan.…
