Rspec 不会使这个简单的代码失败，即使它应该

控制器：

class FooController < ApplicationController
  def create
  end
end

控制器规范：

describe FooController
  it "does bar" do
    Foo.should_receive(:new).with("text" => "Lorem ipsum")
    post :create, foo: { "text" => "Lorem ipsum" }
  end
end

当我运行它时，rspec 说它成功了。但是，create 方法中永远不会调用 Foo.new。但是，如果我将 post 函数调用中的 Lorem ipsum 更改为其他内容，则会失败。我希望这会失败，如果我将 Foo.new(params[:foo]) 添加到 create 方法的主体中，就会成功。为什么情况并非如此？

原文

Controller:

class FooController < ApplicationController
  def create
  end
end

Controller spec:

describe FooController
  it "does bar" do
    Foo.should_receive(:new).with("text" => "Lorem ipsum")
    post :create, foo: { "text" => "Lorem ipsum" }
  end
end

When I run this, rspec says that it's a success. However, Foo.new is never called in the create method. If I change the Lorem ipsum in the post function call to something else, however, it fails. I would expect this to fail, and succeed if I added Foo.new(params[:foo]) to the body of the create method. Why is this not the case?

看起来您在描述块上缺少“do”。尝试：

describe FooController do
  it "does bar" do
    Foo.should_receive(:new).with("text" => "Lorem ipsum")
    post :create, foo: { "text" => "Lorem ipsum" }
  end
end

Looks like you are missing a "do" on the describe block. Try:

describe FooController do
  it "does bar" do
    Foo.should_receive(:new).with("text" => "Lorem ipsum")
    post :create, foo: { "text" => "Lorem ipsum" }
  end
end
