TIL: Colorful test output in Go

The standard command line use when testing go:

$ go test
Enter fullscreen mode Exit fullscreen mode

Colors your test output according to your terminal configuration.

@rakyll has implemented a cool tool gotest for coloring your test output, so you have passing tests colored green, failing tests marked red etc.

$ gotest
Enter fullscreen mode Exit fullscreen mode

You can customize the colors for failing tests and passing tests via environment variables using the palette of your terminal.

GOTEST_PALETTE="red,green" gotest
Enter fullscreen mode Exit fullscreen mode

The first color being for failures and the second one being for passes.

To find the colors in for example open the Preferences, your profile and the color tab.

iTerm preferences

Use the names for the colors in the environment variables

Might want to tag/title these with #GoLang as well as #Go. The latter is too short for search results here.
