1. After running d.Cmd(), in case an error is returned, it makes sense to print command output, as its stderr may contain a clue about what went wrong. This is by no means complete, just as far as I could go. 2. In case the comment in c.Assert is a constant string, it's better to provide it as a comment which will be printed. 3. An arbitrary string should not be passed on to a function expecting %-style formatting. Use %s to fix this. 4. Print the output string before transformation, not after. 5. Unify the output format (drop "out:" prefix"). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
