Single line conditionals: line coverage

[Kriechi]

Is it possible to correctly determine the coverage for a single line conditional, e.g.:

foo if bar.present?

As far as I can see this line would be marked as green as soon as the conditional is evaluated, even if it evaluates to false and therefore does not execute the foo statement.
This means that the coverage information about the single foo call is lost.
Ideally the html formatter could split the line somehow to indicate that only the conditional is covered, but not the actual statement.

Is this possible?
Thanks.

Unfotunately, this is not possible because the underlying ruby Coverage library used by simplecov does not support reporting this kind of data (branch/condition coverage). Sorry to dissapoint!

Is this still the case with Ruby >= 2.5?

@joevandyk yes, there's an issue for that.
