Use a pytest fixture when the layout is not important

[Debilski]

Basically I am specifying a dummy layout (on a per-file basis currently), parse and make it available in the dummy_layout_dict fixture variable:

@pytest.fixture
def dummy_layout():
    return """
        ##########
        #  b  y  #
        #a  ..  x#
        ##########
    """

@pytest.fixture
def dummy_layout_dict(dummy_layout):
    # Use this when a simple layout is needed but the details don’t matter
    return pelita.layout.parse_layout(dummy_layout)

Tests can then use it like

def test_something(dummy_layout_dict):
    # do something that needs a dummy_layout_dict but does not really use it
    ...
