Pytest fixture - tmpdir

• Probably the simples fixture that PyTest provides is the tmpdir.
• Pytest will prepare a temporary directory and call the test function passing the path to the tmpdir.
• PyTest will also clean up the temporary folder, though it will keep the 3 most recent ones. (this is configurable)
• tmp_path is pathlib.Path.

import os


def test_something(tmpdir):
    print(tmpdir)      # /private/var/folders/ry/z60xxmw0000gn/T/pytest-of-gabor/pytest-14/test_read0
    print(type(tmpdir)) # _pytest._py.path.LocalPath

    d = tmpdir.mkdir("subdir")
    fh = d.join("config.ini")
    fh.write("Some text")

    filename = os.path.join( fh.dirname, fh.basename )
