def failure_message_when_negated
  if @exact_match
    "expected #{@target.inspect} to not be equal to #{@expected.inspect}, but they are equal"
  else
    "expected files from #{@target.inspect} to not be present in #{@expected.inspect}, but they are"
  end
end

#matches?(target) ⇒ true, false

Parameters:

  • target (String) —

    path to a directory which contains result of executing a method under test.

Returns:

  • (true) —

    when ‘exact_match` is true and `target` mirrors `expected` directory.

  • (true) —

    when ‘exact_match` is false and `target` contains all files from `expected` directory. Extra files in `target` does not affect the result.

  • (false) —

    if ‘target` lacks some files, or has extra files (when `exact_match` is true), or any file in subdirectory differs from according file content.
