assertion operator

基本解释

However, in the event that the server has failed, which is an assertion that must be made by the operator, it is safe to add a second server to this list.
然而，在服务器发生故障时，操作者必须作出断言。为保险起见，在清单中添加另一台服务器。
This assertion will in fact fail the test because the assertion functions provided by the JsUnit framework use the stricter threequals operator as opposed to the equals operator for all comparisons.
实际上这个断言会失败，因为JsUnit框架提供的断言函数对所有的比较采用更严格的三等操作符，而不是相等操作符。
