Assert that a code block/function call raises ``expected_exception``
and raise a failure exception otherwise.
:arg message: if specified, provides a custom failure message if the
exception is not raised
:arg match: if specified, asserts that the exception matches a text or regex
This helper produces a ``ExceptionInfo()`` object (see below).
You may use this function as a context manager::
>>> with raises(ZeroDivisionError):
... 1/0
.. versionchanged:: 2.10
In the context manager form you may use the keyword argument
``message`` to specify a custom failure message::
>>> with raises(ZeroDivisionError, message="Expecting ZeroDivisionError"):
... pass
Traceback (most recent call last):
...
Failed: Expecting ZeroDivisionError
.. note::
When using ``pytest.raises`` as a context manager, it's worthwhile to
note that normal context manager rules apply and that the exception
raised *must* be the final line in the scope of the context manager.
Lines of code after that, within the scope of the context manager will
not be executed. For example::
>>> value = 15
>>> with raises(ValueError) as exc_info:
... if value > 10:
... raise ValueError("value must be <= 10")
... assert exc_info.type == ValueError # this will not execute
Instead, the following approach must be taken (note the difference in
scope)::
>>> with raises(ValueError) as exc_info:
... if value > 10:
... raise ValueError("value must be <= 10")
...
>>> assert exc_info.type == ValueError
Since version ``3.1`` you can use the keyword argument ``match`` to assert that the
exception matches a text or regex::
>>> with raises(ValueError, match='must be 0 or None'):
... raise ValueError("value must be 0 or None")
>>> with raises(ValueError, match=r'must be \d+$'):
... raise ValueError("value must be 42")
**Legacy forms**
The forms below are fully supported but are discouraged for new code because the
context manager form is regarded as more readable and less error-prone.
It is possible to specify a callable by passing a to-be-called lambda::
>>> raises(ZeroDivisionError, lambda: 1/0)
<ExceptionInfo ...>
or you can specify an arbitrary callable with arguments::
>>> def f(x): return 1/x
...
>>> raises(ZeroDivisionError, f, 0)
<ExceptionInfo ...>
>>> raises(ZeroDivisionError, f, x=0)
<ExceptionInfo ...>
It is also possible to pass a string to be evaluated at runtime::
>>> raises(ZeroDivisionError, "f(0)")
<ExceptionInfo ...>
The string will be evaluated using the same ``locals()`` and ``globals()``
at the moment of the ``raises`` call.
.. currentmodule:: _pytest._code
Consult the API of ``excinfo`` objects: :class:`ExceptionInfo`.
.. note::
Similar to caught exception objects in Python, explicitly clearing
local references to returned ``ExceptionInfo`` objects can
help the Python interpreter speed up its garbage collection.
Clearing those references breaks a reference cycle
(``ExceptionInfo`` --> caught exception --> frame stack raising
the exception --> current frame stack --> local variables -->
``ExceptionInfo``) which makes Python keep all objects referenced
from that cycle (including all local variables in the current
frame) alive until the next cyclic garbage collection run. See the
official Python ``try`` statement documentation for more detailed
information.
