Question

我创建了一个MatDialog组件，我在另一个组件中使用它。它工作正常，但我无法在我使用对话框传递的组件上进行测试测试失败：错误：找不到具有id＆＃34;对话框＆＃34;。

的列

我调用对话框的组件：

import { ConfirmDialogComponent } from '../../shared/modals/confirm-dialog/confirm-dialog.component';

constructor(private userService: UserService, private dialog: MatDialog) { }

openDialog(user: User): void {
    const dialogRef = this.dialog.open(ConfirmDialogComponent, {
      width: '250px',
      data: { tille: 'Confirm box', msg: 'Are you sure you want to delete this user?' }
    });

    dialogRef.afterClosed().subscribe(result => {
      if (result === 'OK') {
        this.dataSource.deleteUsers(user, this.paginator.pageIndex, this.paginator.pageSize, this.sort.active, this.sort.direction, this.input.nativeElement.value);
      }
    });
  }

测试

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import {SharedModule} from '../../shared/shared.module';
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { DebugElement } from '@angular/core';

import { ListUserComponent } from './list-user.component';
import { UserService } from '../user.service';
import { RouterTestingModule } from '@angular/router/testing';
import { GraphqlModuleModule } from '../../graphql-module/graphql-module.module';
import { MatDialog } from '@angular/material';

describe('ListUserComponent', () => {
  let component: ListUserComponent;
  let fixture: ComponentFixture<ListUserComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [BrowserAnimationsModule, SharedModule, RouterTestingModule, GraphqlModuleModule],
      declarations: [ListUserComponent],
      providers: [UserService, { provide: MatDialog, useValue: {} }]
    })
      .compileComponents();
  }));

  beforeEach(() => {
    fixture = TestBed.createComponent(ListUserComponent);
    component = fixture.componentInstance;
    fixture.detectChanges();

    // UserService actually injected into the component
    // const userService = fixture.debugElement.injector.get(UserService);
    // Setup spy on the `getQuote` method
    // spyOn(userService, 'getUsers').and.returnValue(Promise.resolve(getUsers));
  });

  it('should create', () => {
    expect(component).toBeTruthy();
  });
});

ConfirmDialogComponent是SharedModule的exports，declarations和entryComponents列表

哪些版本的Angular，Material，OS，TypeScript，浏览器都会受到影响？

Angular：5.2.1 材料：5.1.0 Windows 10，
