Parametrized tests

[radarhere]

Helps #6525

[Yay295]

test_image_resize.py can be parametrized more than that (I had to change the file extension to upload it here). test_image_resize.txt

Here too:

Pillow/Tests/test_image_resample.py

Lines 516 to 518 in 0ed03d4

	@pytest.mark.parametrize("mode", ("RGB", "L", "RGBA", "LA", "I", ""))
	def test_formats(self, mode):
	for resample in [Image.Resampling.NEAREST, Image.Resampling.BILINEAR]:

can be:

    @pytest.mark.parametrize("resample", (Image.Resampling.NEAREST, Image.Resampling.BILINEAR))
    @pytest.mark.parametrize("mode", ("RGB", "L", "RGBA", "LA", "I", ""))
    def test_formats(self, resample, mode):

It looks like you only parametrized one parameter, but the @pytest.mark.parametrize annotation can do more than that.

Looks good, thanks!

Please can you merge/rebase to include #6529 and make sure the Windows tests pass?
