How to set request args with Flask test_client?

I have to test out a certain view that gets certain information from request.args.

I can't mock this since a lot of stuff in the view uses the request object.
The only alternative I can think of is to manually set request.args.

I can do that with he test_request_context(), e.g:

with as req:
req.request.args = {'code': 'mocked access token'}

Now the request inside this view will have the arguments that I've set.
However I need to call my view, not just initialize it, so I use this:

with as c:
resp = c.get('/myview')

But I don't know how to manipulate the request arguments in this manner.

I have tried this:

with as c:
with as req:
req.request.args = {'code': 'mocked access token'}
resp = c.get('/myview')

but this does not set request.args.

Pass the query_string argument to c.get, which can either be a dict, a MultiDict, or an already encoded string.

with app.test_client() as c:
    r = c.get('/', query_string={'name': 'davidism'})

The test client request methods pass their arguments to Werkzeug's EnvironBuilder, which is where this is documented.
