Minitest Shopify

Prototype of a minitest test class with capybara assertions capable of rendering sections and snippets of a liquid based Shopify theme.

Example

MinitestShopify.configure do |config|
  config.theme_root = File.join(__dir__, "theme")
  config.selenium_driver = :selenium_chrome_headless
  config.layout_file = "layout/theme"
end

require "minitest/autorun"
require "minitest-shopify"

class TestCard < MinitestShopify::LiquidTest
  def test_renders_a_card
    render template: "snippets/card", variables: { comment: default_comment }
    assert_text "Hello world!"
    assert_text "John Doe"
  end

  private

  def default_comment
    {
      id: 1,
      created_at: "2023-07-20T19:31:35Z",
      content: "Hello world!",
      author: {
        id: 1,
        name: "John Doe"
      }
    }
  end
end

You can also use selenium to run tests that involve JavaScript or assets:

require "minitest/autorun"
require "minitest-shopify"

class TestCardView < MinitestShopify::ViewTest
  def test_javascript_enabled_card
    render template: "snippets/js-card", variables: { comment: default_comment }
    within "#comment-1" do
      assert_text "Javascript is enabled"
      assert_no_text "Hello World"
    end
  end

  private

  def default_comment
    {
      id: 1,
      content: "Hello world!",
    }
  end
end
