[x] bug report

Current behavior When running tests, I get the error:

> mocha build/test
  ODataService -
    1) "before each" hook for "Construct via injection"

  0 passing (41ms)

My test looks like:

require('zone.js');
import 'reflect-metadata';
import { assert } from 'chai';
import { Observable, Operator } from 'rxjs/rx';
import { Location } from '@angular/common';
import { inject, TestBed } from '@angular/core/testing';
// import { TestBedHelper } from './testbedHelper';
import { MockBackend } from '@angular/http/testing';
import { BaseRequestOptions, Http, ConnectionBackend, HttpModule } from '@angular/http';
import { IEmployee } from './employee';
import { ODataOperation } from '../operation';
import { ODataServiceFactory } from '../odataservicefactory';
import { ODataConfiguration } from '../config';

describe('ODataService - ', () => {
    beforeEach(() => {
        TestBed.configureTestingModule({
            providers: [
                BaseRequestOptions,
                MockBackend,
                {
                    provide: Http, useFactory: (backend: ConnectionBackend, defaultOptions: BaseRequestOptions) => {
                        return new Http(backend, defaultOptions);
                    },
                    deps: [MockBackend, BaseRequestOptions]
                },
                ODataConfiguration,
                ODataServiceFactory
            ],
            imports: [
                HttpModule
            ]
        });
    });

    it('Construct via injection', inject([ ODataServiceFactory ], (factory: ODataServiceFactory) => {
        // Act
        let service = factory.CreateService<IEmployee>('Employees');

        // Assert
        assert.isNotNull(service);
    }));
});

Fixed it for me

The most important thing is to keep import section like it was right after “ng new myproject”. For me import ‘zone.js/dist/zone-testing’ should be at the top of all imports:

import 'zone.js/dist/zone-testing';
// tslint:disable-next-line:ordered-imports
import { getTestBed } from '@angular/core/testing';
import { BrowserDynamicTestingModule, platformBrowserDynamicTesting } from '@angular/platform-browser-dynamic/testing';

declare const require: any;

// First, initialize the Angular testing environment.
getTestBed().initTestEnvironment(BrowserDynamicTestingModule, platformBrowserDynamicTesting());
// Then we find all the tests.
const context = require.context('./', true, /\.spec\.ts$/);
// And load the modules.
context.keys().map(context);
