 ## Building/rebuilding containers
 
 While we don't recommend building containers locally, it is possible.
 For instructions on how to build or rebuild containers manually using [Docker](https://www.docker.com) and [Singularity](https://docs.sylabs.io) refer to [`<container_template>/docker/README.md`](https://github.com/precimed/container_template/blob/main/docker/README.md).
 
+## Unit tests
+
+Unit tests are available in the `<container_template>/tests` directory. 
+These are run using the [pytest](https://docs.pytest.org/en/stable/) framework, and part of the GitHub Actions workflow.
+To run the tests locally, issue:
+
+```bash
+cd <container_template>
+(pip install pytest)  # if not already installed
+py.test -v tests
+```
+
 ## Build the documentation
 
 Within this repository, the html-documentation can be built from source files put here using [Sphinx](https://www.sphinx-doc.org/en/master/index.html).
