javascript - AngularJS & Karma-Jasmine - Not working if verifyNoOutstandingExpectation(); or verifyNoOutstandingRequest(); stands alone

Question

I have one http request that has not been flushed, so when I have it like this

afterEach(function(){
      $httpBackend.verifyNoOutstandingExpectation();
      $httpBackend.verifyNoOutstandingRequest();
});

It works as expected and I get

Error: Unflushed requests: 1

The error message comes from $httpBackend.verifyNoOutstandingRequest();, but when I have it like this

afterEach(function(){
    $httpBackend.verifyNoOutstandingRequest();
});

No error is thrown.

Why is it so ? Do I have to alwys keep the both method together ?

Answer 1

在 AngularJS 文档中它说

verifyNoOutstandingExpectation();

验证通过 expect api 定义的所有请求都已发出。如果未发出任何请求，verifyNoOutstandingExpectation 将引发异常。

所以这可能是您没有定义任何期望调用但使用 verifyNoOutstandingExpectation 的原因，因此它引发了异常。
