+## Testing
+
+To test this rules there are real tests - those can be executed via:
+
+`cd tests && bazel test --config=gcc13 //...`
+
+Note the Bazel config depends on the use operating system and compiler setup.
+Use `--config=gcc13` for Ubuntu 24.04 and GCC13,
+use `--config=vs2022` for Windows and Visual Studio 2022,
+and use `--config=macos` for macOS and Apple Clang.
+
+Besies real test, there a also some test project located in the tests folder.
+
+A minimal criteria for change and modification to this codebase is to ensure that 
+the project in the tests folder can be build without any problems, i.e.:
+
+
+```shell
+bazel build --config=gcc13 //hello_world:hello_world
+bazel build --config=gcc13 //horch:main
+bazel build --config=gcc13 //moc_test:main
+bazel build --config=gcc13 //qml_demo:qt_demo
+bazel build --config=gcc13 //uic_demo:main
+```
+
+You should also be able to run this binary:
+
+```shell
+bazel run --config=gcc13 //moc_test:main
+```
