+pytest test coverage for the GenerateWebIDLBindings.py script
+=============================================================
+
+This directory contains tests for the GenerateWebIDLBindings.py script,
+which is used to parse the WebExtensions APIs schema files and generate
+the corresponding WebIDL definitions.
+
+See ["WebIDL WebExtensions API Bindings" section from the Firefox Developer documentation](https://firefox-source-docs.mozilla.org/toolkit/components/extensions/webextensions/webidl_bindings.html)
+for more details about how the script is used, this README covers only how
+this test suite works.
+
+Run tests
+---------
+
+The tests part of this test suite can be executed locally using the following `mach` command:
+
+```
+mach python-test toolkit/components/extensions/webidl-api/test
+```
+
+Write a new test file
+---------------------
+
+To add a new test file to this test suite:
+- create a new python script file named as `test_....py`
+- add the test file to the `python.ini` manifest
+- In the new test file make sure to include:
+ - copyright notes as the other test file in this directory
+ - import the helper module and call its `setup()` method (`setup` makes sure to add
+ the directory where the target script is in the python library paths and the
+ `helpers` module does also enable the code coverage if the environment variable
+ is detected):
+ ```
+ import helpers # Import test helpers module.
+ ...
+
+ helpers.setup()
+ ```
+ - don't forget to call `mozunit.main` at the end of the test file:
+ ```
+ if __name__ == "__main__":
+ mozunit.main()
+ ```
+ - add new test cases by defining new functions named as `test_...`,
+ its parameter are the names of the pytest fixture functions to
+ be passed to the test case:
+ ```
+ def test_something(base_schema, write_jsonschema_fixtures):
+ ...
+ ```
+Create new test fixtures
+------------------------
+
+All the test fixture used by this set of tests are defined in `conftest.py`
+and decorated with `@pytest.fixture`.
+
+See the pytest documentation for more details about how the pytest fixture works:
+- https://docs.pytest.org/en/latest/explanation/fixtures.html
+- https://docs.pytest.org/en/latest/how-to/fixtures.html
+- https://docs.pytest.org/en/latest/reference/fixtures.html
