Solution

  • There's actually two different types of lines in your screenshots.

    The ones close to the thin vertical continuous line is about local changes to the file. Green means "new lines", blue means changed lines and a little arrow pointing towards the code means removed lines.

    The colored lines further to the left are about code coverage. Green means that this line was executed (covered) and red means it was not executed.
