rspec 参数测试失败

Question

我是 rails 的新手，我正在尝试为控制器方法创建编写规范测试，但我不知道如何将参数用户传递给 get 方法。这是项目控制器的创建方法

  def create
      @project = Project.new(project_params)
      @project.creator = current_user
      byebug
      if params[:project][:users].any?
        byebug
        params[:project][:users].reject!(&:empty?)
        @project.enrolled_user = User.find( params[:project][:users])
      end
    byebug
      authorize @project
      respond_to do |format|
        if @project.save
          format.html { redirect_to @project, notice: 'Project was successfully 
           created.'}
          format.json { render :show, status: :created, location: @project}
        else
          format.html { render :new}
          format.json { render json: @project.errors, status: :unprocessable_entity}
        end
      end
    end

project_spec.rb

  context "post create" do
  it "creates a new project" do
    get :new
    byebug
   
    post :create,params: { user: user.id }
    byebug
    

    expect(project1.creator).to eq(user)
    expect(enrolled_user.user_id).to eq(user1.id)
    expect(response).to be_successful
  end
end

您确实需要系统测试而不是控制器测试来实现测试您在此处描述的功能的要求。所以 Rspec 加上 Capybara 可以让你做这样的事情

所以使用railsgrspec:system项目并做类似

的测试

  it "Can create a project" do
    administrator_sign_in #some system test helper that creates a user and logs a user in if needed, there are plenty of examples on how to do helpers like this.
    visit '/admin/projects'
    click_link "New" 
    #save_and_open_page #Uncomment this if you want to see what your form fields are, unstyled, can be very useful when trying to see what to fill in and what button and links to press and click
    fill_in "Name", with: "New project"
    fill_in "Other project fields", with: "Some Data"
    page.check("Name of a boolean field") #check a checkbox
    click_button("Create Project")
    project = Project.find_by name: "New project"
    expect(current_path).to eq("/admin/projects/#{project.id}")
    expect(page).to have_content("Project was successfully created")
    expect(project.name_of_boolean_field).to be true
  end
