test.each: Allow test name to not include every test arg

[wcauchois]

Regarding the test.each function:

Right now when you provide a test name, the arguments to the test from each are appended to that name even if you don't provide any placeholders, due to the behavior of util.format. For example, the test

test.each([
  'foo',
  'bar'
])('description of test', () => { /* ... */ })

would run the tests "description of test foo" and "description of test bar". Sometimes this is not desirable. For example, if the test arguments are long strings this would bloat the output.

Could we come up with a better formatting mechanism that would allow users more control over this behavior?

Strange I’ve not noticed this but I was using vsprint before instead of Node Util format I’d say this is definitely a bug. I’ll try and get this sorted ASAP

@mattphillips That's awesome, thank you! Out of curiosity, why aren't you using sprintf? I took a look at the docs and it seems much more flexible than util.format.

(in general, not this specifically. And I'm not opposed to switching, I didn't think about these edge cases when suggesting util.format)

Gotcha. Thanks again!
