Why "rv" in Flask testing tutorial? [closed]

Question

I am reading Flask's tutorial about testing. There's such code there:

rv = self.app.get('/')
assert 'No entries here so far' in rv.data

My question is: why is there a variable called rv? What does this abbreviation mean?

I've been looking for it in Flask source code for a while, and I found several variables called that way:

app_rv = app(environ, start_response)

and

rv = run_wsgi_app(self.application, environ, buffered=buffered)

But, as you can see, rv here is not even possibly related to rv as response object in testing.

I've been able to find out that "r" stays probably for "response", but what does the "v" mean?

Answer 1

It says just below that code snippet in your link you provided:

By using self.app.get we can send an HTTP GET request to the application with the given path. The return value will be a response_class object.

So rv is just short for return value.
