Question

这是我正在测试的控制器中的操作。

def create
  user = User.find_by(email: params[:email])

  if user && user.authenticate(params[:password]) 
    login_user!(user)
  else
    flash[:danger] = "Something was wrong with your username or password."
    render :new
  end
end

这是我对此行动的规范

describe "POST create" do
  let!(:bob) { Fabricate(:user, email: "bob@bob.com") }

  it "sets user to the user with a matching email" do 
    post :create, email: "bob@bob.com"
    expect(assigns(:user)).to eq(bob)
  end
end

当我运行时，它说

 expected: #<User id: 1, email: "bob@bob.com", password_digest: "$2a$04$e5M21As5A6HaGBhaFsfzE.9hw4mlfYDPQbOCB9VggAI...", full_name: "Sidney D'Amore MD", created_at: "2014-07-29 15:42:02", updated_at: "2014-07-29 15:42:02">
        got: nil

我在这里缺少什么？在我看来，HTTP请求应该触发此行

user = User.find_by(email: params[:email])

并将user分配给bob

将您的操作更改为使用实例变量（@user）。无法在rspec中测试局部变量赋值

def create
  @user = User.find_by(email: params[:email])

  if @user && @user.authenticate(params[:password]) 
    login_user!(@user)
  else
    flash[:danger] = "Something was wrong with your username or password."
    render :new
  end
end

Rspec - 测试POST请求中变量的赋值
