如何避免 RSpec 3.0 中 stub_chain 的弃用警告? [英] How to avoid deprecation warning for stub_chain in RSpec 3.0?

问题描述

当我使用 stub_chain 运行测试时，我会收到弃用警告.

When I run a test with stub_chain, I'll get a deprecation warning.

describe "stubbing a chain of methods" do
  subject { Object.new }

  context "given symbols representing methods" do
    it "returns the correct value" do
      subject.stub_chain(:one, :two, :three).and_return(:four)
      expect(subject.one.two.three).to eq(:four)
    end
  end
end

弃用警告:不推荐使用 rspec-mocks 的旧 :should 语法中的 stub_chain 而不显式启用该语法.改用新的 :expect 语法或显式启用 :should.

Deprecation Warnings: Using stub_chain from rspec-mocks' old :should syntax without explicitly enabling the syntax is deprecated. Use the new :expect syntax or explicitly enable :should instead.

如何避免这种警告?

推荐答案

RSpec.configure do |config|
  config.mock_with :rspec do |c|
    c.syntax = [:should, :expect]
  end
end

请注意，它设置的是 rspec-mocks 语法，而不是 rspec-expectations 语法，正如 Paul 的回答所示.

Notice that it's setting the rspec-mocks syntax, not the rspec-expectations syntax, as Paul's answer shows.
