class TestEnvironment
Defined at line 32 of file ../../sdk/lib/driver/testing/cpp/internal/test_environment.h
The |TestEnvironment| manages the mocked test environment that the driver being tested uses.
It provides the server backing the driver's incoming namespace. This incoming namespace can
be customized by the user through the |incoming_directory| method. The |TestEnvironment|
uses a fdf::OutgoingDirectory which can support driver transport. Therefore it must be used
with an fdf_dispatcher.
# Thread safety
This class is thread-unsafe. Instances must be managed and used from a synchronized dispatcher.
See
https://fuchsia.dev/fuchsia-src/development/languages/c-cpp/thread-safe-async#synchronized-dispatcher
If the dispatcher used for it is the foreground dispatcher, the TestEnvironment does not need to
be wrapped in a DispatcherBound.
If the dispatcher is a background dispatcher, the suggestion is to wrap this inside of an
|async_patterns::TestDispatcherBound|.
