Without explicitly setting the encoding to "utf-8" I get the following error on windows (python 3.9)
```
File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 115, in handle
self.get_schema(schema, out, indent)
File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 72, in get_schema
self.save_graphql_file(out, schema)
File "D:\env\lib\site-packages\graphene_django\management\commands\graphql_schema.py", line 59, in save_graphql_file
outfile.write(print_schema(schema.graphql_schema))

```
I think it might be helpful to add an explicit hint that HTTP headers should be prepended with `HTTP_` as required by `django.test.Client` (at least it was not super obvious to me when I tried to use it).
* Use the Django Client test utility instance that Django provides with its TestCase class. This allows GraphQL tests to make use of the stateful client methods like login()
* Add missing test case initializer call
* Don't break backward compability
* Add test for pending deprecation warning on GraphQLTestCase._client

* merge master into v3
* fix order_by snake casing by checking if value is None, switch executor to execution_context_class since schema.execute no longer supports executor
* fix linting by removing duplicate defintion and test of convert_form_field_to_string_list
* Handle Django database atomic requests
* Create and handle database atomic mutations
* Make code compatible with Python 2.7
* Code style
* Define set_rollback instead of using the one in rest_framework.views because of backward compatibility
* Implement mock.patch.dict
* Fix issue #1055
* Fix if to elif
* Use self.stdout.write instead of print when printing graphql schema

* fix( DjangoListField ): test that default functionality should resolve/call queryset at view time, first attempt at solution
* fix( DjangoListField ): DjangoListField defines get_manager just like DjangoConnectionField for a better variable name default_manager instead of default_queryset
* fix: apply specific black formatting
In general I welcome reviews even from non-maintainers to build confidence. I haven't seen any objections and this has sat with approval for a week so I am going to go ahead and merge.
* Add a default msg to show the response content.
This seems like an issue with using assertResponseNoErrors and assertResponseHasErrors
Which doesn't include any errors specific to the response and currently just shows.
```python
self.assertNotIn("errors", list(content.keys()))
AssertionError: 'errors' unexpectedly found in ['errors', 'data']
```
* Update testing.py
