You don't mention what you want from testing so it's hard to say which
is "best" as it depends on one's point of view.

For example, I had a requirement to test more than just Python
programs. I wanted to test code written in any language. None of the
frameworks I found supported this so I wrote my own tester. It
interacts with programs via file streams - principally stdin, stdout
and stderr though others can be added as needed.

One nice by-product is that test code does not bloat-out the original
source which remains unchanged. And test cases can be written before,
alongside or after the code as desired.

So, YMMV.
