REF/CLN: test_get_dummies
lgtm. merge on green.
 > and to be redundant with the test method names (TestGetDummmies.test_basic by TestGetDummmies.test_get_dummies_basic)?

In this case it is redundant, but in many other cases we'll see something like `test_basic` in a class without an informative name. It's also not uncommon to see tests for something other than get_dummies living inside a TestGetDummies class.  I think being explicit is worthwhile here.

> Is there an ongoing effort to replace pd.DataFrame by DataFrame in our code

Not that I'm aware of.  For files testing lower-level code, I like to have all the relevant imports at the top so that it is easy to tell what is tested in this file.  If `pd` is in the namespace, I can't rule anything out.  Not really relevant for this file, just a habit I've gotten into. updated with typo fixup + green > (for example, I would personally prefer to always have the module name and not import objects).

Yea @jorisvandenbossche and I agree, but at the same time I think someone needs to champion that cause if we want to establish a standard

i have always been in favor of this :)

moving to this will require a good code check though - s may need be that easy IMO this doesn't necessarily require a code check initially. 
But we could already just stop merging PRs that do changes like `pd.DataFrame` -> `DataFrame` (or ask them to revert that part). @WillAyd gave the comment like https://github.com/pandas-dev/pandas/pull/33184#issuecomment-606957773 on several PRs recently I think, but in the end we always just merged the PR.. I care most about consistency in a single file meaning we shouldn’t mix ways of referencing common things like Series vs pd.Series

I do prefer using import of Series and not pd.Series

 > I do prefer using import of Series and not pd.Series

I am confused now. I interpreted the above "i have always been in favor of this" as the opposite (https://github.com/pandas-dev/pandas/pull/33184#issuecomment-606961547), since that is replying to a quote of Will that is basically saying that he, Marc and I prefer to not import objects but modules (so using `pd.Series` instead of `Series`) >  I think someone needs to champion that cause if we want to establish a standard

I opened a separate issue about it: https://github.com/pandas-dev/pandas/issues/33203. Let's try to decide there which of the two ways has our preference.
