template <typename Configuration>class BackgroundDriverTest
Defined at line 321 of file ../../sdk/lib/driver/testing/cpp/driver_test.h
Background driver tests have the driver-under-test executing on a background driver dispatcher.
This allows for tests to use sync FIDL clients directly from their main test thread.
This is good for unit tests that more heavily exercise the driver-under-test through its exposed
FIDL services, rather than its public methods.
The test can run tasks on the driver context using the |RunInDriverContext()| methods, but sync
client tasks can be run directly on the main test thread.

template <typename T>T RunInDriverContext (fit::callback<T (DriverType &)> task)Runs a task on the dispatcher context of the driver under test. This will be a different
thread than the main test thread, so be careful when capturing and returning pointers to
objects that live on different dispatchers like test fixture properties, or the environment.
Returns the result of the given task once it has completed.
