使用Jasmine测试一个方法，该方法从viewChild调用另一个方法

// 引入要测试的代码文件
import { Component, ViewChild } from '@angular/core';

// 引入Jasmine框架
import { TestBed } from '@angular/core/testing';
import { ComponentFixture } from '@angular/core/testing';
import { By } from '@angular/platform-browser';
import { MyComponent } from './my.component';

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

  beforeEach(async () => {
    await TestBed.configureTestingModule({
      declarations: [MyComponent]
    }).compileComponents();
  });

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

  it('should call another method from viewChild', () => {
    // 调用viewChild方法
    component.viewChildMethod();

    // 断言另一个方法是否被调用
    expect(component.anotherMethod).toHaveBeenCalled();
  });
});
