javascript - Angular ngMock 有时会因无待处理请求而失败

Question

如果我将呼叫保持在$httpBackend.flush()原处，则测试将失败No Pending Requests，但预期会通过。如果我注释掉flush电话，期望会失败。当我在获取日期的服务中放置一个断点时，它被调用并且承诺正在解决，我可以进入addIssues它被调用。会不会是另一个导致它的测试？

 it("should pass",
          function() {
            scope.issues = [];
            scope.requestChanges.issues = [
              {
                title: "File Mismatch",
                affects_2d_file: true,
                affects_3d_file: true,
                resolved_at: null
              },
              {
                title: "Missing Files",
                affects_2d_file: true,
                affects_3d_file: true,
                resolved_at: null
              }
            ];

            spyOn(TEST.$state, "go");
            spyOn(TEST.notification_service, "pushSuccessMessage");

            TEST.$httpBackend.expectPOST("/some/url")
              .respond(200,{
                part_issues: scope.requestChanges.issues
              });

            scope.addIssues(); //this makes makes the http request.

            TEST.$httpBackend.flush(); //expects pass, but no pending request
            scope.part.issues.forEach(function(e, i) {
              var issue = e;
              var change = scope.requestChanges.issues[i];
              expect(_.isEqual(issue, change)).toBe(true);
            });
            //TEST.$httpBackend.flush(); expects fail
          });

我确实有TEST.$httpBackend.expectGET("/some/url").respond(200,part)一个beforeEach。flush（在 beforeEach 中没有调用）
