+## CI
+
+In CI, this test is run in the Docker container `lin/midas_base_gitea`. To
+manually run tests in the CI environment, log into the runner machine and use
+
+```bash
+sudo docker run --rm -it -v "$PWD":/workspace -w /workspace lin/midas_base_gitea bash
+```
+
+Please note that `EPICS_HOST_ARCH` is `linux-x86_64` within that container!
+Therefore, that environment variable must not be set explicitly within the test.
