Thanks Dan, that's it.

And you're also right: it's ugly.

I was hoping to find a quick way to do it in a short time.
It is interesting, and I will develop something around that.

Nice colored formating, how do you did that?

>     result = function_under_test('https://www.google.nl', False)
>     str(result)

>     r.text.__str__.assert_not_called()

I still not "like" that way either.

What is the effect of: str(result) ?

Regards,
Sylvain.
