Current behavior
I have noticed that injecting services in combination with TestBed compile/configureTestingModule fails. To reproduce this I have modified a test from @juliemr test seed project:

import {
} from '@angular/core/testing';
import { Component } from '@angular/core';
import { BorderComponent } from '../app/border-component';
import { UserService } from '../app/user-service';

  template: '',
  directives: [BorderComponent]
class TestComponent {

describe('greeting component', () => {
  beforeEach(() => {
      declarations: [TestComponent],
      providers: [UserService]

  //injecting here fails
  it('should create component', async(inject([UserService],(service) => {
    TestBed.compileComponents().then(() => {
      var fixture = TestBed.createComponent(TestComponent);
      var compiled = fixture.debugElement.nativeElement;

If I remove inject the test will pass. I have also seen the same result if I try to inject in a beforeEach
The error I am getting is

Error: This test module uses the component BorderComponent which is using a "templateUrl", but they were never compiled. Please call "TestBed.compileComponents" before your test.

Yes I will, but I think further discussion should be moved to gitter or stackoverflow, as this is more a support request, than a bug report.
I usually structure my tests like this. Note, that I have written this on mobile, so there might be a syntax error somewhere. But the idea should be clear.

describe('greeting component', () => {

  let fixture: ComponentFixture<TestComponent>;

  beforeEach(() => {
    return TestBed.configureTestingModule({
      declarations: [TestComponent],
      providers: [UserService]
    }).compileComponents().then(() => {
        fixture = TestBed.createComponent(TestComponent);

  afterEach(() => {

  it('should create component', inject([UserService], (service: UserService) => {
      // Perform test using fixture and service

Other Answers:

You have to return the promise from TestBed#compileComponents in the beforeEach hook. Otherwise the tests will run before the components were compiled.
