+# Web Bluetooth API Tests
+
+The Web Bluetooth API enables sites to connect to and interact with Bluetooth
+Low Energy devices. Please check the [Web Bluetooth specification] for more
+details.
+
+Web Bluetooth testing relies on the [FakeBluetooth][Web Bluetooth
+Testing] test API which must be provided by browsers under test.
+
+TODO([#485]): Update the links to [FakeBluetooth][Web Bluetooth Testing] to
+point to the [Testing Web Bluetooth specification].
+
+In this test suite `resources/bluetooth-test.js` detects and triggers
+the API to be loaded as needed. This file also contains test helper methods,
+such as for asserting that Bluetooth events are fired in a specific order.
+The `resources/bluetooth-fake-devices.js` contains several helper methods that set
+up fake Bluetooth devices.

+
+## 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
+```
+
+More details can be found in `generate.py` and `generate_test.py`.
+
+## Chromium Implementation
+The Chromium implementation is provided by
+`../resources/chromium/web-bluetooth-test.js` using [MojoJS].
+
+The Chromium implementation is not included in stable Chrome builds since it
+would add too much to the binary size. On Chromium infrastructure, it is run
+using the `content_shell` executable.
+
+In the future, Chromium `src/device/bluetooth` may be refactored into a Mojo
+service. At this point, it would be possible to add the necessary testing hooks
+into stable Chrome without substantially increasing the binary size, similar to
+WebUSB.
+
+These Bluetooth tests are upstreamed here because other browsers can reuse them
+by implementing the [Web Bluetooth Testing] API, even if only on their internal
+infrastructure.
+
+For more implementation details, see the [Web Bluetooth Service README].
