我在Jasmine和Karma中有很多依赖于$httpBackend HTTP模拟检查的测试.当我今天升级Angular时,他们停止了工作.
假设我的Jasmine测试中有这样的东西：
// Arrange
httpBackend.expect('POST','https://localhost:44300/api/projects/1/samples').respond(fakedDto);
// Act
scope.updateSamples();
httpBackend.flush();
在最后一行,这是完全可以的,我收到：
TypeError: $browser.$$checkUrlChange is not a function in C:/SVN/samplemgmt/src/ClientApp/client/bower_components/angular/angular.js (line 12502) $RootScopeProvider/this.$get</Scope.prototype.$digest@C:/SVN/samplemgmt/src/ClientApp/client/bower_components/angular/angular.js:12502:9 createHttpBackendMock/$httpBackend.flush@C:/SVN/samplemgmt/src/ClientApp/client/bower_components/angular-mocks/angular-mocks.js:1481:5 @C:/SVN/samplemgmt/src/ClientApp/tests/integration/sample/samplecreationController_integration.test.js:341:9
此外,我有通常的配置来结束测试：
afterEach(function () {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});

我很欣赏一些如何让事情再次发挥作用的建议.最近是否对httpBackend测试做了任何更改？
对于那些坚持使用旧版Angular并且由于某种原因无法在此时升级的人来说,here是一个很好的帖子,它解释了正在发生的事情以及如何解决问题.
原文链接：/angularjs/141195.html总结一下 –
出现此问题是因为$httpBackend.flush()和$httpBackend.verifyNoOutstandingExpectation()错误地尝试进行摘要.显然,内部的(来自verifyNoOutstandingExpectation()调用)失败.幸运的是,我们可以指示它不要执行摘要 – 请注意错误的参数：
afterEach(function() {
$httpBackend.verifyNoOutstandingExpectation(false); // <-- here
$httpBackend.verifyNoOutstandingRequest();
});
