import { UsersProvider } from '../providers/users/users';
import { TestBed, inject } from '@angular/core/testing';
import { HttpClientTestingModule, HttpTestingController } from '@angular/common/http/testing';
import { Http } from '../../node_modules/@angular/http';

let zone: any;
describe("TEST 1", () => {
let service: UsersProvider;
    let httpMock: HttpTestingController;
    beforeEach(() => {
        TestBed.configureTestingModule({
            providers: [UsersProvider]
        });
        service = TestBed.get(UsersProvider);
    });

    afterEach(() => {
        httpMock.verify();
    });

    describe('#registerUser tests', () => {
        it("Equality Test", function () {
        expect("Hello").toEqual("Hello");
        });
    });
});

By setting random to false we have no longer been seeing these issues. We did this by adding this setting in the karma.conf.js:

config.set({
    client: {
      jasmine: {
        random: false
      }
    }
  });

Try it out .
