As documentation says, empty ranges are equals.
Therefore, I decided to write a few tests for it

This looks redundant. Didn't that test function already test equality and hash equality of several empty ranges? Even inequality? I see three empty ranges among the test ranges defined at the top, and all pairs of them get tested:

https://github.com/Eclips4/cpython/blob/b91788d368e8441dfab3a84e1b5acfc03b743c23/Lib/test/test_range.py#L639-L660

If you want to test your particular two ranges, maybe instead just add them to all those test ranges?

This reverts commit dca27a6. Added tests are redundant with existing tests.
