Shoulda

Shoulda helps you write more understandable, maintainable Rails-specific tests under Minitest and Test::Unit.

📢 See what's changed in recent versions.

As an umbrella gem, the shoulda gem doesn't contain any code of its own but rather brings in behavior from two other gems:

• Shoulda Context
• Shoulda Matchers

For instance:

require "test_helper"

class UserTest < ActiveSupport::TestCase
  context "associations" do
    should have_many(:posts)
  end

  context "validations" do
    should validate_presence_of(:email)
    should allow_value("user@example.com").for(:email)
    should_not allow_value("not-an-email").for(:email)
  end

  context "#name" do
    should "consist of first and last name" do
      user = User.new(first_name: "John", last_name: "Smith")
      assert_equal "John Smith", user.name
    end
  end
end

Here, the context and should methods come from Shoulda Context; matchers (e.g. have_many, allow_value) come from Shoulda Matchers.

See the READMEs for these projects for more information.

Shoulda is tested and supported against Ruby 3.0+, Rails 6.1+, RSpec 3.x, Minitest 4.x, and Test::Unit 3.x.
