g ddlZ ddlZddlmZmZeeddZn #e$rdZYnwxYwesddZGddZdSdS) N)skipraises_running_pytestFc|t|St|r' |n #|$rYdSwxYwtdt|trt dt d)a Tests that ``code`` raises the exception ``expectedException``. ``code`` may be a callable, such as a lambda expression or function name. If ``code`` is not given or None, ``raises`` will return a context manager for use in ``with`` statements; the code to execute then comes from the scope of the ``with``. ``raises()`` does nothing if the callable raises the expected exception, otherwise it raises an AssertionError. Examples ======== >>> from symengine.pytest import raises >>> raises(ZeroDivisionError, lambda: 1/0) >>> raises(ZeroDivisionError, lambda: 1/2) Traceback (most recent call last): ... AssertionError: DID NOT RAISE >>> with raises(ZeroDivisionError): ... n = 1/0 >>> with raises(ZeroDivisionError): ... n = 1/2 Traceback (most recent call last): ... AssertionError: DID NOT RAISE Note that you cannot test multiple statements via ``with raises``: >>> with raises(ZeroDivisionError): ... n = 1/0 # will execute and raise, aborting the ``with`` ... n = 9999/0 # never executed This is just what ``with`` is supposed to do: abort the contained statement sequence at the first exception and let the context manager deal with the exception. To test multiple statements, you'll need a separate ``with`` for each: >>> with raises(ZeroDivisionError): ... n = 1/0 # will execute and raise >>> with raises(ZeroDivisionError): ... n = 9999/0 # will also execute and raise N DID NOT RAISEz'raises(xxx, "code")' has been phased out; change 'raises(xxx, "expression")' to 'raises(xxx, lambda: expression)', 'raises(xxx, "statement")' to 'with raises(xxx): statement'z1raises() expects a callable for the 2nd argument.)
