运行在 Rspec 中的特定测试后块之后

Question

有什么方法可以运行 after/before 阻止 after/before 使用标签的特定测试？

我有 3 个 it 块

describe "describe" do

  it "test1" do
  end

  it "test2" do
  end

  after(<<what goes here??>>) do
  end

end

我如何运行仅在 test2 之后的 after 块？这可能吗？

Answer 1

是的，你可以做到，看看here

您可以在 rspec

中使用 metadata 来实现

RSpec.configure do |config|
  config.treat_symbols_as_metadata_keys_with_true_values = true
end

describe "Skip hook demo" do
  # If prior to RSpec 2.99.0.beta1
  after do
    puts "before hook" unless example.metadata[:skip]
  end

  # If RSpec 2.99.0.beta1 or later
  after do |example|
    puts "before hook" unless example.metadata[:skip]
  end

  it "will use before hook" do
  end

  it "will not use before hook", :skip do
  end
end

Answer 2

您应该使用 contexts 来执行此操作。类似于：

describe "describe" do
  context 'logged in' do
    before(:each) do
      # thing that happens in logged in context
    end

    after(:each) do
      # thing that happens in logged in context
    end

    it "test1" do
    end
  end

  context 'not logged in' do
    # No before/after hooks here. Just beautiful test isolation

    it "test2" do
    end
  end
end

在 before/after 块中有 if/else 个条件是一种代码味道。不要那样做。它只会使您的测试变得脆弱、容易出错且难以更改。

Answer 3

最好的方法就是使用 context。例如：

describe "AutomateFr33k's fr33ky tests" do

  it "runs test1" do
    expect(true).to be_true
  end

  context "do something afterwards" do
    after { puts "running something after test2!" }

    it "runs test2" do
      expect(5).not_to eq(4)
    end
  end
end
