Web Bluetooth Testing

Web Bluetooth testing relies on the Web Bluetooth Testing API which must be provided by browsers under test.

In this test suite resources/bluetooth-helpers.js detects and triggers the API to be loaded as needed.

The Chromium implementation is provided by ../resources/chromium/web-bluetooth-test.js.

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.

Generated gen-* files from generate.py

generate.py builds gen-*.html tests using templates in script-tests/*/*.js.

The subdirectory structure in bluetooth/script-test/* is recreated into bluetooth/*. The generator expands each CALL function from templates into new leaf directories and files.

Example:

script-tests/server/get-same-object.js contains:

gattServer.CALLS([
        getPrimaryService('heart_rate')|
        getPrimaryServices()|
        getPrimaryServices('heart_rate')[UUID]]),

Generating:

server/getPrimaryService/gen-get-same-object.html
server/getPrimaryServices/gen-get-same-object.html
server/getPrimaryServices/gen-get-same-object-with-uuid.html

Usage:

$ python generate.py
