# Run performance tests based on Gatling Provide a complete Gatling performance testing setup for Java Maven projects by adding the required test dependencies and Gatling Maven plugin configuration, creating or guiding Java simulation placement, and explaining how to run simulations and inspect reports. **What is covered in this Skill?** - Add Gatling dependencies and the `gatling-maven-plugin` to `pom.xml` - Project structure: `src/test/java` for Java simulations and `src/test/resources` for Gatling configuration, feeders, templates, and logging - Run simulations with `./mvnw gatling:test` - Select a simulation with `-Dgatling.simulationClass=<FullyQualifiedClassName>` when multiple simulations exist - Use `./mvnw gatling:help -Ddetail=true -Dgoal=test` to inspect available plugin options - Review generated Gatling run output and reports under the build output directory **Scope:** Use Gatling through the Maven plugin for Java simulations. Prefer project-local Maven wrapper commands when available. ## Constraints Gatling setup must be Maven-based, reproducible, and compatible with Java project conventions. Prefer official Gatling Maven plugin behavior and avoid inventing unsupported command-line options. - **PREREQUISITE**: Verify the project is Maven-based and prefer `./mvnw` when the Maven wrapper exists - **BUILD CONFIGURATION**: Add Gatling dependencies with test scope and configure `io.gatling:gatling-maven-plugin` in `pom.xml` - **VERSION SELECTION**: Use the pro...
