Overview

One file's accumulated coverage, against state this object owns outright rather than rebuilt for each merged pair.

Constructor Details

#initialize(coverage, branches:, methods:) ⇒ MergedFile

A criterion is carried for this file when the data carries it, not when this process happens to measure it. A merge runs on behalf of the processes that produced the resultsets and does not necessarily share their configuration: simplecov merge never ran SimpleCov.start at all, and dropping a table it did not ask for would lose branch data the producers did measure. A nil table means nobody measured that criterion; an empty one means it was measured and the file has none.

  # Branch coverage always reports a table, even an empty one, so
  # `SourceFile` can tell "no branches in this file" from "branch
  # coverage was off". Method coverage stays `nil` until some resultset
  # actually carries methods.
