    Parameters
    url_map : mapping[str or file-like object -> str or file-like object]
    The mapping to use to redirect read_csv calls.
    module : module, optional
    The module to patch ``read_csv`` on. By default this is ``pandas``.
    This should be set to another module if ``read_csv`` is early-bound
    like ``from pandas import read_csv`` instead of late-bound like:
    ``import pandas as pd.
pd.read_csv``.
    strict : bool, optional
    If true, then this will assert that ``read_csv`` is only called with
    elements in the ``url_map``.'
