有没有办法在 RSpec 中首先运行嵌套的过滤器？

Question

describe 'Feature' do
  before do
    setup
  end

  describe 'Success' do
    before do
      setup_for_success
    end

    specify 'It works' do
      ...
    end
  end
end

RSpec 将始终运行setup之前的setup_for_success. 有没有办法先跑setup_for_success？

Answer 1

before(:all)您可以通过在尝试之前确定要运行的范围来做到这一点before(:each)：

describe 'Feature' do
  before(:each) do
    puts "second"
  end

  describe 'Success' do
    before(:all) do
      puts "first"
    end

    specify 'It works' do
      ...
    end
  end
end

编辑：

在 Rspec 2 中，操作按以下顺序运行：

before suite
before all
before each
after each
after all
after suite

以下是文档的链接，显示了调用方法的顺序： https: //www.relishapp.com/rspec/rspec-core/v/2-2/docs/hooks/before-and-after-hooks#块按顺序运行之前/之后

显然，在 Rspec 3.5 中，before 块调用具有不同的命名，但也有效。它们按以下顺序运行：

before :suite
before :context
before :example
after  :example
after  :context
after  :suite

describe 'Feature' do
  before(:example) do
    puts "second"
  end

  describe 'Success' do
    before(:context) do
      puts "first"
    end

    specify 'It works' do
      ...
    end
  end
end
