Post 'if' coverage and ternary operator

[arthurkarganyan]

Hi!

I am worried about missing one line when you use post 'if' condition. E.g. in such way there is one missing line if a = nil.

if a.present?
b = 10
end

But if I write it in this way, there will be no line missing.

b = 10 if a.present?

Also, this will happen when using ternary operator. Is there any way to avoid this issue?

Nope. Ruby’s standard library provides line-level (a.k.a. c0) code coverage. Unfortunately, we can’t get more granular than that. There’s a three-year-old issue to add c1 code coverage to the Ruby standard library but there hasn’t been any progress on it, as far as I know.

@sferik I think we need to start a 'standard responses' section like what nokogiri has https://github.com/sparklemotion/nokogiri/blob/master/STANDARD_RESPONSES.md I don't really see a good, visible place in the README for it.
