+## Testing against multiple targets
+
+> [!WARNING]
+> Currently, the following only works in combination with [Blackbox Test Suites configured by the _org.gradlex.java-module-testing_ plugin](https://github.com/gradlex-org/java-module-testing?tab=readme-ov-file#blackbox-test-suites).
+
+Tests run against the _primary_ target, which is either the local machine you run the build on, or what is configured via `javaModulePackaging.primaryTarget(...)`.
+If you want to run the test multiple times against each target you configured, you can configure this as follows:
+
+```
+javaModulePackaging {
+    multiTargetTestSuite(testing.suites["test"])
+}
+```
+
+Then, there will be a test task available for each target, such as `testWindows-2022` or `testMacos-14`.
+
 ## Running on GitHub Actions
 
 Target-specific _tasks_ such as `assembleWindows-2022` or `assembleMacos-14` only run on the fitting operating system and architecture.
