"""Simulate that a pipeline is currently running.
You can use this context manager to test packages that rely on third party auth.
This uses `mock.patch` to override some calls in `third_party_auth.pipeline`,
so you will need to provide the "target" module *as it is imported*
in the software under test. For example, if `foo/bar.py` does this:
>>> from third_party_auth import pipeline
then you will need to do something like this:
>>> with simulate_running_pipeline("foo.bar.pipeline", "google-oauth2"):
>>> bar.do_something_with_the_pipeline()
If, on the other hand, `foo/bar.py` had done this:
>>> import third_party_auth
then you would use the target "foo.bar.third_party_auth.pipeline" instead.
Arguments:
pipeline_target (string): The path to `third_party_auth.pipeline` as it is imported
in the software under test.
backend (string): The name of the backend currently running, for example "google-oauth2".
Note that this is NOT the same as the name of the *provider*. See the Python
social auth documentation for the names of the backends.
Keyword Arguments:
email (string): If provided, simulate that the current provider has
included the user's email address (useful for filling in the registration form).
fullname (string): If provided, simulate that the current provider has
included the user's full name (useful for filling in the registration form).
username (string): If provided, simulate that the pipeline has provided
this suggested username. This is something that the `third_party_auth`
app generates itself and should be available by the time the user
is authenticating with a third-party provider.
Returns:
None
