Is there an alternative for the soon-to-be-deprecated pandas.util.testing.assert_produces_warning?

I don't see one in the API, though the warning suggests it should be available:

In [1]: import pandas

In [2]: from pandas.util.testing import assert_produces_warning
/home/mghenis/anaconda3/bin/ipython:1: FutureWarning: pandas.util.testing is deprecated. Use the functions in the public API at pandas.testing instead.
  #!/home/mghenis/anaconda3/bin/python


In [3]: from pandas.testing import assert_produces_warning
---------------------------------------------------------------------------
