+# OCPP Integration Tests
+
+This directory contains some test tooling and integration tests
+for OCPP1.6 and OCPP2.0.1.
+
+## Run the tests
+
+All tests are run via the unified `tests/run-tests.sh` script from the
+repository root. The script handles parallel execution, network-isolation
+setup/teardown and certificate/config installation automatically.
+
+```bash
+# From the repository root:
+tests/run-tests.sh ocpp          # all OCPP tests (1.6, 2.0.1, 2.1)
+tests/run-tests.sh ocpp16        # OCPP 1.6 only
+tests/run-tests.sh ocpp201       # OCPP 2.0.1 only
+tests/run-tests.sh ocpp21        # OCPP 2.1 only
+tests/run-tests.sh --serial ocpp # run serially
+tests/run-tests.sh -j4 ocpp     # limit to 4 parallel workers
+tests/run-tests.sh --help        # show all options
+```
+
+Tests run in parallel by default. The time depends on your system;
+it usually takes a couple of minutes.
+Check the generated `report.html` for detailed results.
+
+You can also run individual test sets or test cases using
+
+```bash
+python3 -m pytest test_sets/ocpp201/remote_control.py::test_F01_F02_F03
+```
+
+This runs test case `test_F01_F02_F03`
+specified in `test_sets/ocpp201/remote_control.py`.
+
+If you run the test cases individually,
+make sure to have all required certificates and configs
+for the test cases installed using the
+convenience scripts inside [test_sets/everest-aux](test_sets/everest-aux/)
+
+```bash
+./install_certs <path-to-EVerest-installation-directory>
+./install_configs <path-to-EVerest-installation-directory>
