This looks like bad coding style to me--trying to cram too much on a line and an overly complex conditional expression.

Using the same three lines, you could instead assign each result to a temporary var:

    x = outputs.get("foo.bar.baz", "default")
    y = pytest.approx(time_recorder.time_taken, abs=0.0001)
    assert x == y

If using an assert method, I think this looks okay too (although still a bit noisy):

    self.assertEqual(
        outputs.get("foo.bar.baz", "default"),
        pytest.approx(time_recorder.time_taken, abs=0.0001),
    )

I find that if black produces ugly output, it's usually because of something that I could improve, and I appreciate the hint.
