错误

Failure/Error: assert_select "tr>td", :text => "MyString".to_s, :count => 2 Test::Unit::AssertionFailedError: <"MyString"> expected but was <"unknown\n\t\t\t\t(MyString)"> false is not true.

请帮忙解决这个问题...

Answer 1

assert_select "tag", "String" 仅匹配 <tag>String</tag>。如果你想要部分匹配，你可以使用正则表达式 assert_select "tag", /String/，匹配 <tag>a String</tag>.

在你的情况下这应该有效：

assert_select "tr>td", :text => /MyString/, :count => 2

Failure/Error: assert_select "tr>td", :text => "MyString".to_s, :count => 2

Failure/Error: assert_select "tr>td", :text => "MyString".to_s, :count => 2
