I want to make extending custom cases easier, rather than having a massive test case that's hard to read / understand

Looks great! One question for discussion, but not required.

[aswamy]

I wrote JS doc for a typescript function for optional params. I even had square bracket for optional params, but when you hover over the function, it doesn't show it with square brackets in the hover text.

• Should we do something like for ours as well?
• Or should we have an explicit "optional" after the paramName?

Suggestion:

I like this idea! It's more expressive. Let's go in this direction :)
