Since these parameters are reused, it would make sense to make them fixtures (or global variables, but that's not as neat). As an example, you would do something like

Since these parameters are reused, it would make sense to make them fixtures (or global variables, but that's not as neat). As an example, you would do something like

@pytest.fixture
def NCHAN():
    return 128

@pytest.fixture
def NTIMES():
    return 10

@pytest.fixture
def TOL():
    return 1e-6

def test_delay_filter_2D(NCHAN, NTIMES, TOL):
    ...

Though I don't like the aesthetics of using fixtures with all capital letters (I prefer to write them as I would a local variable, in all lowercase, with underscores where appropriate).
