As far as I understand all test run on a given text file. And compare this

to a expected output. Then they run again but this time using the result

from the first run.


I guess the purpose is to soo that it does not get changed again

because it is already the expected output.


After running all tests there are 3 or so in the repo that fail in the

second run. How important is it to fix these? Because they were

there for some time.
