【问题描述】：

我有一组有序的测试，它们模仿用户操作并相互依赖。

如何将database_cleaner 配置为在这些有序测试过程中不清理数据库？

/spec/support/database_cleaner.rb:

RSpec.configure do |config|
  config.before(:suite) do
    DatabaseCleaner.clean_with(:truncation)
  end

  config.before(:each) do
    DatabaseCleaner.strategy = :transaction
  end

  config.before(:each, js: true) do
    DatabaseCleaner.strategy = :truncation
  end

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
end

测试样本：

RSpec.describe Conversation, type: :model, order: :defined do
  context 'by default' do
    before :context do
      @alice = create :user
      @bob = create :user
      @subject = 'subject'
      @body = 'body'
      @conversation = @alice.send_message(@bob, @subject, @body)
    end

    it 'should have the subject it was opened with' do
      expect(@conversation.subject).to eq @subject
    end

    it 'should have one message upon opening' do
      expect(@conversation.messages.count).to eq 1
    end

    it 'should be initiated by @alice' do
      expect(@conversation.initiator).to eq @alice
    end

    it 'should be received by @bob' do
      expect(@conversation.recipient).to eq @bob
    end

    it 'should have two messages when bob sends a new message' do
      @conversation.add_message(@bob, 'This is my second message')
      expect(@conversation.messages.count).to eq 2
    end
end

标签： ruby-on-rails rspec database-cleaner

【解决方案1】：

修复它。我的测试是随机运行的，除了这些之外，它们都有order: :defined 标签。所以我在support/database_cleaner.rb 的config.before 语句中添加了一个unless 条件。

现在看起来像这样：

  config.before(:each) do
    DatabaseCleaner.start
  end

  config.after(:each) do
    DatabaseCleaner.clean
  end
