Detect Hypothesis tests
-----------------------
How to dynamically determine whether a test function has been defined with Hypothesis.
Via ``is_hypothesis_test``
~~~~~~~~~~~~~~~~~~~~~~~~~~
The most straightforward way is to use |is_hypothesis_test|:
.. code-block:: python
from hypothesis import is_hypothesis_test
@given(st.integers())
def f(n): ...
assert is_hypothesis_test(f)
This works for stateful tests as well:
.. code-block:: python
from hypothesis import is_hypothesis_test
from hypothesis.stateful import RuleBasedStateMachine
class MyStateMachine(RuleBasedStateMachine): ...
assert is_hypothesis_test(MyStateMachine.TestCase().runTest)
Via pytest
~~~~~~~~~~
If you're working with :pypi:`pytest`, the :ref:`Hypothesis pytest plugin <pytest-plugin>` automatically adds the ``@pytest.mark.hypothesis`` mark to all Hypothesis tests. You can use ``node.get_closest_marker("hypothesis")`` or similar methods to detect the existence of this mark.
