    assert 1 == 1

add_nunit_attachment

Add an attachment to a node test-case by calling the add_nunit_attachment(path: str, description: str) function with the filepath and a description.

def test_attachment(add_nunit_attachment):
    pth = os.path.join(os.path.abspath(os.path.dirname(__file__)), 'fixture.gif')
    add_nunit_attachment(path, "peanut butter jelly time")
    assert 1 == 1
