Instance Method Details

#[](line) ⇒ Object

Return the coverage status for the requested line. There are four possible return values:

  • nil if there’s no information for the requested line (i.e. it doesn’t exist)

  • true if the line was reported by Ruby as executed

  • :inferred if rcov inferred it was executed, despite not being reported by Ruby.

  • false otherwise, i.e. if it was not reported by Ruby and rcov’s heuristics indicated that it was not executed
