def warns_deprecated_sympy():
    '''Shorthand for ``warns(SymPyDeprecationWarning)``

    This is the recommended way to test that ``SymPyDeprecationWarning`` is
    emitted for deprecated features in SymPy. To test for other warnings use
    ``warns``. To suppress warnings without asserting that they are emitted
    use ``ignore_warnings``.

    >>> from sympy.utilities.pytest import warns_deprecated_sympy
    >>> from sympy.utilities.exceptions import SymPyDeprecationWarning
    >>> import warnings

    ...     SymPyDeprecationWarning("Don't use", feature="old thing",
    ...         deprecated_since_version="1.0", issue=123).warn()

    >>> with warns_deprecated_sympy():
    ...     pass
    Traceback (most recent call last):

    SymPyDeprecationWarning was emitted. The list of emitted warnings is: [].
