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，在服務器發生故障時，操作者必須作出斷言。爲保險起見，在清單中添加另一台服務器。
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.
實際上這個斷言會失敗，因爲JsUnit框架提供的斷言函數對所有的比較採用更嚴格的三等操作符，而不是相等操作符。
