如何从现有的 Rails 6 应用程序中删除 Minitest？

Question

我想达到与this question 完全相反的效果。我已经包含了 rspec，它运行良好，但是在运行 rake 时，我得到：

WARN: Unresolved or ambiguous specs during Gem::Specification.reset:

Please report a bug if this causes problems. 

我知道删除其中一个最简单的版本会停止警告，但我根本不关心警告。我的关键点是删除一些我在项目中没有使用的套件。有什么办法吗？

Answer 1

我要做的是创建一个带有单元测试的 Rails 测试安装和一个没有：

rails new tester

和

rails new tester --skip-test

您必须在单独的文件夹中执行此操作，以免它们发生冲突。

然后您可以在两个文件夹之间进行比较，以找到您需要在安装中更改的内容。

Visual Studio 代码有一个名为“比较文件夹”的插件，它应该可以解决问题。

--- 完成上述操作后---

看起来您唯一需要做的事情是：

• 删除 Gemfile 中的测试部分

• 运行bundle

然后修改config/application.rb文件如下：

来自

    require_relative "boot"

    require "rails/all"

    # Require the gems listed in Gemfile, including any gems
    # you've limited to :test, :development, or :production.
    Bundler.require(*Rails.groups)

    module Tester
      class Application < Rails::Application
        # Initialize configuration defaults for originally generated Rails version.
        config.load_defaults 6.1

        # Configuration for the application, engines, and railties goes here.
        #
        # These settings can be overridden in specific environments using the files
        # in config/environments, which are processed later.
        #
        # config.time_zone = "Central Time (US & Canada)"
        # config.eager_load_paths << Rails.root.join("extras")
      end
    end

到

    require_relative "boot"

    require "rails"
    # Pick the frameworks you want:
    require "active_model/railtie"
    require "active_job/railtie"
    require "active_record/railtie"
    require "active_storage/engine"
    require "action_controller/railtie"
    require "action_mailer/railtie"
    require "action_mailbox/engine"
    require "action_text/engine"
    require "action_view/railtie"
    require "action_cable/engine"
    require "sprockets/railtie"
    # require "rails/test_unit/railtie"

    # Require the gems listed in Gemfile, including any gems
    # you've limited to :test, :development, or :production.
    Bundler.require(*Rails.groups)

    module Tester
      class Application < Rails::Application
        # Initialize configuration defaults for originally generated Rails version.
        config.load_defaults 6.1

        # Configuration for the application, engines, and railties goes here.
        #
        # These settings can be overridden in specific environments using the files
        # in config/environments, which are processed later.
        #
        # config.time_zone = "Central Time (US & Canada)"
        # config.eager_load_paths << Rails.root.join("extras")

        # Don't generate system test files.
        config.generators.system_tests = nil
      end
    end

这是使用 Rails 6.1.3。
