How can I colorize the default Go test output?

Colorizing Default Go Test Output

The native testing package in Go lacks built-in colorized output. However, you can leverage an external tool like grc (generic colourizer) to colorize test results.

Using grc for Colorization

Install grc using your preferred package manager (e.g., apt-get install grc for Debian/Ubuntu). After installation, create a configuration file (~/.grc/grc.conf) with the following entry:

^([/\w\.]+\/)?go test\b
conf.gotest

Next, create a grc configuration file for customizing Go test output colors (~/.grc/conf.gotest):

# Go test grc colorizer configuration
regexp==== RUN .*
colour=bright_blue
-
regexp=--- PASS: .* (\(\d+\.\d+s\))
colour=green, yellow
-
...

Running Colorized Tests

Now, you can run your Go tests with colorization using the following command:

grc go test -v ./..

Aliases for Convenience

To simplify the process, add an alias to your shell's configuration file:

alias go=grc go

This allows you to run colorized tests simply by using the "go test" command.
