+that are used in the tests to set up fake Bluetooth devices and to assert that
+specific Bluetooth events happened.
 
+[Web Bluetooth specification]: https://WebBluetoothCG.github.io/web-bluetooth
+[Web Bluetooth Testing]:
+https://docs.google.com/document/d/1Nhv_oVDCodd1pEH_jj9k8gF4rPGb_84VYaZ9IG8M_WY/
+[#485]: https://github.com/WebBluetoothCG/web-bluetooth/issues/485
+[Testing Web Bluetooth specification]:
+https://WebBluetoothCG.github.io/web-bluetooth/tests.html
+
+## Generated Tests
+
+Several Web Bluetooth tests share common test logic. For these tests, the
+`script-tests` directory contains templates that are used by the
+`generate.py` script to create several tests from these templates. The templates
+are JavaScript files that contain a `CALLS()` keyword with functions delimited by
+a `|` character. A test will be created for each function in the `CALLS()` by
+`generate.py`. Note that for each subdirectory in `script-tests` there is a
+matching directory under `bluetooth`. The generator will expand `CALLS`
+functions into the
+corresponding directory.
+
+### Example
+
+The `./script-tests/server/get-same-object.js` contains the following
+code:
+
+```js
+gattServer.CALLS([
+        getPrimaryService('heart_rate')|
+        getPrimaryServices()|
+        getPrimaryServices('heart_rate')[UUID]]),
+```
+
+The functions in `CALLS()` will be expanded to generate 3 test files prefixed
+with `gen-`:
+
+```
+bluetooth/server/getPrimaryService/gen-get-same-object.html
+bluetooth/server/getPrimaryServices/gen-get-same-object.html
+bluetooth/server/getPrimaryServices/gen-get-same-object-with-uuid.html
+```
+
+### Generate Tests
+
+To generate the tests in `script-tests`, run the following command from the
+source root:
+
+```sh
+$ python bluetooth/generate.py
+```
+
+To check that generated tests are correct and that there are no obsolete tests,
+or tests for which a template does not exist anymore, run:
+
+```sh
+$ python bluetooth/generate_test.py

+At the moment, the origin policies starting at 100 downward have special handling in the `/.well-known/origin-policy` handler, and might require consulting that file to get the full context. The ones starting at 1 upward are handled generically. If they ever start meeting in the middle we can reevaluate this scheme.
