Description

Can we have an option to colorize "expected" and "actual" in test output? Like this: Screenshot from 2020-05-13 18-27-59

For me the colors helps because it allows me to locate the diff faster. This kind of coloring is very common in Node.js test frameworks.

Contributor guide

Research direction
Investigate how to add optional colorization to the 'expected' and 'actual' values in test output. Look at how testify formats output, possibly using terminal escape codes or a library like fatih/color. Ensure the feature is opt in via a flag or environment variable.
