Overview

Resolves the test files a mutant should be run against.

Three sources, in precedence order: a caller-supplied resolver lambda, a fixed list, or the integration's own per-subject selection. The first two exist so a survivor rerun or a per-test-coverage run can narrow the selection without the integration knowing about it.

Precedence is by key presence, not truthiness: an explicit empty list means "no tests cover this", which the scheduler turns into :no_coverage. Falling through to the integration there would silently widen the selection back out.

def for(mutant)
  if @options.key?(:test_file_resolver)
    @options[:test_file_resolver].call(mutant)
  elsif @options.key?(:test_files)
    @options[:test_files]
  else
    @integration.select_tests(mutant.subject)
  end
end

#resolved_empty?(test_files) ⇒ Boolean

True when the resolver was asked and came back empty. Only meaningful for a resolver-driven run: a fixed empty test_files list is a deliberate "run nothing", not an absence of coverage.

Returns:

  • (Boolean)
