This page describes testing APIs for both clients and implementation of the Bluetooth component.
There are also notable higher level bluetooth tests:
test/mock_bluetooth_* files provide GoogleMock based fake objects that subclass the cross platform C++ device/bluetooth API.
These are used by numerous clients and are stable.
WORK IN PROGRESS.
Web Platform Tests for Web Bluetooth are being refactored to use
That library is implemented over a mojo interface
fake_bluetooth.mojom in bluetooth/public/mojom/test and is implemented in the
fake_bluetooth.mojom interface is not intended to be used directly.
web-bluetooth-test.js makes the Fake Bluetooth interface easier to work with.
If another C++ client intends to use Fake Bluetooth a C++ wrapper similar to
web-bluetooth-test.js should be created.
When a Bluetooth service is created the
bluetooth/test/fake_* files should be removed and the client facing test wrapper
web-bluetooth-test.js converted to implement the Bluetooth service as needed for tests.
New feature development uses cross platform unit tests. This reduces test code redundancy and produces consistency across all implementations.
Unit tests operate at the public
device/bluetooth API layer and the
BluetoothTest fixture controls fake operating system behavior as close to the platfom as possible. The resulting test coverage spans the cross platform API, common implementation, and platform specific implementation as close to operating system APIs as possible.
test/bluetooth_test.h defines the cross platform test fixture
BluetoothTestBase. Platform implementations provide subclasses, such as
test/bluetooth_test_android.h and typedef to the name
Early code (Classic on most platforms, and Low Energy on BlueZ) was tested with platform specific unit tests, e.g.
bluetooth_adapter_win_unittest.cc. The BlueZ style has platform specific methods to create fake devices and the public API is used to interact with them.
Maintenance of these earlier implementation featuress should update tests in place. Long term these tests should be refactored into cross platform tests.
Bluetooth controller system tests generating radio signals are run and managed by the Chrome OS team.
