[FIXED] Hypothesis - reuse @given between tests

Issue

I've been using hypothesis for some time now. I'm wondering how I could reuse @given parts.

Some of the ones I have are like 20 lines and I copy the whole @given part above a couple of the test cases.

A simple example of a test

@given(
    some_dict=st.fixed_dictionaries(
        {
            "test1": st.just("name"),
            "test2": st.integers()
            }
        )
    )
def test_that uses_some_dict_to_initialize_object_im_testing(some_dict):
    pass

What would be the best way to go around reusing @given blocks?

Solution

Create your own decorator:

def fixed_given(func):
    return given(
        some_dict=st.fixed_dictionaries(
            {
                "test1": st.just("name"),
                "test2": st.integers()
            }
        )
    )(func)


@fixed_given
def test_that_uses_some_dict_to_initialize_object_in_testing(some_dict):
    pass
