Documentation

Released version

Why

Sometimes it is easier to commit expected directory structure and compare it with a directory created by a method under test.

If you prefer DSL-like expectations, see minitest-filesystem.

Installation

Add this line to your application's Gemfile and run bundle:

gem 'assert_dirs_equal', require: false

Usage

class MyWriter
  def self.perform
    File.write("/tmp/my_writer/result.txt", "Hello world!")
  end
end

Create a file "result.txt" with "Hello world!" in "test/fixtures/case01".

Minitest

require 'minitest/assert_dirs_equal'

class MyWriterTest < Minitest::Test
  def test_perform
    MyWriter.perform
    assert_dirs_equal "test/fixtures/case01", "/tmp/my_writer"
  end
end

RSpec

TODO

Known issues

Due that Rubinius String#strip doesn't fail on binary data (undocumented behaviour), the library will try to actually diff binary files. Depending on your test framework's diffing tool, it may or may not be a problem. For example, Minitest is not affected, since it uses shell diff under the hood.

Origin

Extracted from Torba library since it looks more like a standalone component.
