Ruby on rails Rspec在控制器中更新失败

以下是客户控制器中更新的rspec错误：

 5) CustomersController GET customer page 'update' should be successful
     Failure/Error: put 'update', id => 1, :customer => {:name => 'name changed'}
       <Customer(id: integer, name: string, short_name: string, contact: string, address: string, country: string, phone: string, fax: string, email: string, cell:

        @subject ='Customer info was changed BY' + session[:user_name]

有什么想法吗？谢谢。

发布的值（通过

参数访问）是字符串。纠正测试的最简单方法是让
客户。应该接收（：find）。使用（“1”）。并返回（客户）

请注意，我们现在使用“1”（即字符串）作为预期参数，而不是1（FixNum）。
所有参数都作为字符串传递，我相信find方法正在对整数进行隐式对话。要么在控制器中显式使用to_i，要么更改您的规范以期望字符串“1”。
这是与（“1”）一起使用后的错误：5）CustomerController获取客户页面“更新”应成功失败/错误：put'update'，：id=>1，：customer=>{:name=>'name changed'}Mock“customer_1001”收到意外消息：更改为（无参数）#./app/controllers/customers\u controller.rb:46:in
update'./spec/controllers/customers\u controller\u spec.rb:41:in
block（3层）in'这是因为您正在调用
@customer.changed
，但尚未中断该方法。您需要存根该方法，或者使用真实的模型实例，以便
@customer.changed
能够正确计算。是的，您是对的。存根类似于：customer.stub（：changed.），并且返回（false）以绕过发送电子邮件。但是遇到了另一个问题，那就是如何测试：重定向到会话[（'page'+会话[：page\u step].到_s）.到_sym]，：notice=>“客户已成功更新！”？另一个问题。通过使用存根按需返回值，我们真的测试了代码中的任何内容吗？或者只是为了自我安慰而让它通过。你应该能够用
响应测试这一点。应该重定向到（会话[（'page'+会话[：page\u步骤]）。到。到sym]）
。rspec测试的工作方式是在每个测试中只测试一件事情。其他所有内容都是存根的，因此每个测试都是独立的。因此，您应该使用另一个测试来检查
@customer.changed
是否正常工作。这样你就有了适当的测试覆盖率。
