This picks up the work from #1321 on top of the work from #1940.
It allows the user to choose a compact tests format, or to override the labels with their own text or symbols.
We use arrow functions in most places; this enforces it.
Passing arrow functions to Mocha is discouraged: https://mochajs.org/#arrow-functions
This was a mix of autofixes and hand adjustments.
Provide greater consistency for badges related to versions. Fix#1181.
- the `version` function in `color-formatters` was previously returning the colour of the badge, but also its text with a leading _v_. It was broken down into two separate functions and the text formatting part was moved to `text-formatters`, where it really belongs.
- unit tests were added for these two functions in `color-formatters.spec` and `text-formatters.spec`, using Sazerac.
- as discussed in #1181, the leading _v_ was omitted for _xxxx-yy-zz_ date patterns. Any future exceptions can easily be added to the `ignoredVersionPatterns` pattern.
- the badge colour was previously switched to orange if a hyphen was found in the version string. This didn't seem ideal, instead pattern matching is done to find keywords such as `beta`, `alpha` or `snapshot`. Of course, this list can easily be extended.
- all badges related to versions now use the `versionText` and `versionColor` functions. There are a few rare exceptions, for instance in cases where the data returned by the service's API allows to figure things out without relying on any parsing/pattern matching (eg. `badgeData.colorscheme = prerelease ? 'orange' : 'blue';`, where `prerelease` is determined from an API's response).
Because I despise nitpicking stuff like indentation and spacing in pull request comments, I'd like to nudge forward our automated style checking, at least for new files being added.
I don't want to totally rewrite server.js just to get automated style checking… the blame tracking is just too useful. So let's it's just take care of that when we start splitting it out.
More discussion in #948.
