Comment (by Adam (Chainz) Johnson):
> Well it might generate quite lot of output
A valid concern, but normally more output is better for debugging. Most
functions have a handful of locals. Pytest shows locals by default as
well, so there's a precedent.
> it potentially can output secrets that you don't want to leak out.
I don't think this is much of a concern, normally those with the ability
to see test results already have the ability to see or run the test code,
and thus find the secrets. Additionally, many test assertions already can
output secrets.

features of ​pytest.
I agree, we don't want Django's test framework to reinvent the wheel. But
this feature is only providing the ability to use something already within
unittest.
I'd be in favour of passing `tb_locals=True` always, instead of adding a
flag to make it optional. Using a flag would make the feature hard to
discover feature and "yet another thing to think about." Users can
override the test runner themselves as shown to undo this change if they
want.
