[ new ] interactive test runner

[gallais]

New interactive mode for the test runner.

• Print diff in case of mismatch (using git diff)
• Ask user whether they want to overwrite the current golden value

New options syntax for the test runner.

• --interactive flag
• --only should be the last flag and followed by a list of cases of interest. As before, if the list is empty we run all the tests.

Nice!

Thanks for this, it will help things out greatly.

I was thinking, could we get a flag --accept to provide a default yes answer for accepting new tests.

Running yes y | make test should do the trick.

Yes, indeed it will. I was thinking that --accept would be that little bit better and not reliant on having yes.
