Description

In an attempt to eliminate the possibility of a trivial regression, tests should be included to verify that

  • Success messages are output to the console with a green colour; and,
  • error messages are output to the console with a red colour!

I haven't included these tests as I'm not yet sure how to go about testing this.

The module I use to colourize the output namely, Chalk, does so by emitting ANSI escape codes however, the terminal interprets these ANSI escape codes before I can evaluate them. Hm :confused:.

Research direction
Start by reviewing existing tests in the repository (likely using a framework like Mocha or Jest) to understand the test setup. Since Chalk emits ANSI escape codes, you'll need to capture stdout/stderr and assert on the raw output. Consider using a library like `mock stdio` or `jest mock process` to intercept console output. Note that Chalk may disable colors in non TTY environments, so you may need to force color output by setting `chalk.level = 1`. Look at how other projects test colored output for inspiration, and ensure tests are written for both success (green) and error (red) cases.
