ruby - 测试需要 HTML 字符串的方法的好方法是什么？

Question

foo.should_receive( :save ).with( html )

HTML 字符串在哪里html，但我不想检查特定的 HTML，因为这会使测试变得脆弱。

有没有办法检查 foo 应该收到的参数的长度？是否可以使用匹配器或类似的东西html.should include '<html'？

在 RSpec 中工作。

Answer 1

I don't see why that would not work using the code you provided. Maybe use include? instead. You also could use a regex to determine if it was HTML. While for this specific example it might be a little much, you may be able to determine more specific things about the html then just if it has that tag.

Answer 2

如上面的评论所述，您可以使用正则表达式作为参数匹配器。

foo.should_receive(:save).with(/<html/)

如果你想做更复杂的断言，你可以提供一个块：

foo.should_receive(:save).with do |arg|
  arg.should include '<html'
end
