What's so good about pytest?

Python coders appear to favor pytest over unittest by a wide margin. What's so good about pytest? Here is a summary:

minimal test coding fuss. No need to derive test from a unittest base class.
pytest shows the intermediate values leading to test failures- without requiring debugging.
simple reusable test fixture setup.
easy to parameterize tests without writing duplicate tests.
can directly kick off pdb debugger in the event of a test failure
marks for allowing selection of tests to execute.
mark groups of tests with decorator @pytest.mark.label
then execute that one group of test with: pytest -m label
can run one a set of matching tests by name with -k
automatic test discovery in folder and subfolders.
many extensions (plugins) are available
pytest-xdist, pytest test.py -n 3, run tests on 3 parallel processes
parameterized, decorate test function with @parameterized.expand(['a','b','c'])
pytest-flake8, pytest --flake8, check code against PEP8 standards
pytest-html, pytest --html=rep.html, generate pretty test result report

-v, -vv, -vvv: verbose and very verbose, very very verbose
--pdb: start pdb debugger when a test fails
-k: run only certain tests using a keyword filter
-s: to display program stdout output while tests are running instead of after failure
-x: exit after first failure
