How to use the schemathesis.checks.status_code_conformance function in schemathesis

    # And "status_code_conformance" is specified
    results = execute(**kwargs, checks=(status_code_conformance,), hypothesis_options={"max_examples": 1})
    # Then there should be a failure
    assert results.has_failures
    check = results.results[0].checks[0]
    assert check.name == "status_code_conformance"
    assert check.value == Status.failure
