Codechange: On regression failure, output the result in a file #8549

merged 1 commit into from Jan 9, 2021

@glx22 glx22 commented Jan 9, 2021

Motivation / Problem

When regression test fails, sometimes our basic diff is not the most usable output. Especially when you are adding more checks to regression test. Having the output in a file can allow use of more avanced tools to compare it with expected output.


On failure simply save the output to a file.
But first I needed to add support for more output lines than expected.
And while in the area I moved the counter increment before diff output, so lines are numbered from 1.
