Confirmed. Instead of deleting just test (which are created in setUp) forms [here](https://github.com/Typeform/typeform-python-sdk/blob/master/typeform/test/test_forms.py#L25) and [here](https://github.com/Typeform/typeform-python-sdk/blob/master/typeform/test/test_responses.py#L26) are deleting of all forms of the selected workspace.

According to API [reference](https://typeform.com/developers/create/reference/update-form-patch/#update-form-patch) you should use list as data payload: `forms.update('form-id', [{"op": "replace", "path": "/title", "value": "foo"}], patch=True)`
