I considered this but in Playgrounds (particularly) on iPad I didn't want to have console output initially. So for me the 'traffic lights' are cleaner.

That said, I'm working on bringing in full Nimble atm -- so if it makes then I can imagine that being nice in the console output at least.

What I mean is replacing the traffic light colours with emoji strings to remove the RGB values. So still traffic lights?

Unless there is a technical limitation why strings aren't possible of course (or at least worse).

Arguably this could be less confusing to the new user than displaying R: 100, G: 0, B: 0 for test results.

Ah I see... I hate those particular emoji haha but maybe you're right. I'll look into that. Will also check that iPad produces the same result.

If the demographic of iPad testing is to let people new to coding get into testing, the tick and cross could further reinforce the success / failure :)

Just a thought though!

True. Although I hate those particular emoji's I also like that fact that these are unlikely to clash/cutter other output. E.g. if I am also outputting color values in my code. It can be somewhat confusing.

For completeness I found my original inspiration for this ticket: https://github.com/Liquidsoul/XCTestPlayground

Ok so @ceeK -- I don't like the clipping on those emoji so I've come up with an alternative.
I also think it brings MORE attention to failed tests and less attention to passing ones.
Thoughts?

+1 on the emojis. It also has better accessibility (color blindness).

The issue with this has been that iPad doesn't show the emoji's unfortunately – but I will definitely include this for the Xcode builds.
