Automatically run test files with pytest (#9576)

* Switch to pytest

git grep -l unittest.main | xargs sed -i 's/unittest.main()/sys.exit(pytest.main([__file__]))/g'
git ls-files -m | xargs -I {} sh -c "echo 'import sys\nimport pytest' >> '{}'"
isort --float-to-top .

* add pytest dep

* use sys.argv
