testing - colorizing golang test run output

Question

I like it when terminal/console test runs actually show their output in either red or green text. It seems like a lot of the testing libraries available for Go have this. However, I'd like to just use the default testing package that comes with Go. Is there a way to colorize it's output with red and green?

You can create a wrapper shell script for this and color it using color escape sequence. Here's a simple example on Linux (I'm not sure how this would look on windows, but I guess there is a way.. :) )

go test -v . | sed ''/PASS/s//$(printf "33[32mPASS33[0m")/'' | sed ''/FAIL/s//$(printf "33[31mFAIL33[0m")/''
