You can add tests for things that don't work yet by using XFAIL. Add `from sympy.utilities.pytest import XFAIL` to the top, and then create a test function like

```py
@XFAIL
def test_integrate_hypertangent_reduced_fail():
    # Add tests here
```

These will show up as an `f` in the tests, but won't cause them to fail. Then, when they start working, they will show up as an `X`, and you can remove the `@XFAIL`.
