We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Use correct test client parameters when sending json body payload
## Problem
Currently, When sending a request containing a json payload using the Django rest framework test client, the payload is being converted into a string using `json.dumps` but the Django rest framework provides convenience parameters that does this automatically.

## Proposed solution
Use the `format` parameter of the DRF test client or set the default payload format in the DRF settings, in order for the test client to be able to handle the conversion automatically
