Question

我有ruby script在运行时从用户那里获取图书的价格。我是为Ruby脚本编写RSpec测试的新手。我使用的是Ruby 1.9.3-p327和rspec 2.11.0。您可以从 Github this link 克隆我的项目。

我的Rspec测试旨在测试新实例化的对象是否属于特定类。

如果我在ruby script中注释第32行，我的测试成功通过。

当我取消注释该行时，我收到的错误与用户输入有关。我甚至没有将此作为spec file的一部分进行测试，但我仍然登陆此错误。我不确切地知道为什么以及如何解决这个问题。

我还想测试此示例的用户输入。如果你能说明我怎么能得到同样的东西，那将是很棒的。我找到了一些我可以开始测试用户输入的地方，例如eg 1和eg 2，但我主要关注如何测试属于哈希的多个元素的用户输入< / p>

感谢。

使用

STDIN.gets.chomp

请参阅this answer。

测试此方法的最佳方法是使用返回预设响应的对象和方法来模拟IO#gets。 RSpec模拟看起来像：

STDIN.should_receive(:gets).and_return("A Book Title")

有关更多示例，请参阅this answer。在适当的before :each块中设置这些内容，它们会拦截您测试中对gets的调用。
