 After running, `run_tests/1` exits with a status code of 0 if all tests that were run succeeded and
 1 otherwise. This makes it possible to check if tests pass inside scripts.
+
+If no tests are found in any of the searched modules, the framework will report an error in red text,
+as this typically indicates a file loading failure (e.g., syntax error). The exit code will be set to 1.
