失败：未定义混合面板-角度测试台

标签： angular typescript angular6 mixpanel testbed

您能告诉我如何在不考虑Mixpanel功能的情况下测试form功能吗？现在它显示以下错误。

login.component.ts 

  ngOnInit() {
    Mixpanel.trackEvent("View Screen", { "Screen Name": "Login" });
    this.createForm();
  }

createForm() {
    this.form = this.fb.group({
      email: ["", Validators.compose([Validators.required, Validators.pattern(RegexValidators.email)])],
      password: ["", Validators.required]
    });
  }

login.component.spec.ts 

import { CoreModule } from './../app.core.module';
import { ReactiveFormsModule, FormsModule } from '@angular/forms';
import { async, ComponentFixture, TestBed } from '@angular/core/testing';
import { LoginComponent } from './login.component';
import { APP_BASE_HREF } from '@angular/common';

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

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      imports: [ReactiveFormsModule, FormsModule, CoreModule],
      declarations: [],
      providers: [
        {
          provide: APP_BASE_HREF,
          useValue: '/'
        }
      ]
    });

    //create component and test fixture
    fixture = TestBed.createComponent(LoginComponent);

    // get test component from the fixture
    component = fixture.componentInstance;
    component.ngOnInit();
  }));

  it('form invalid when empty', () => {
    expect(component.form.valid).toBeFalsy();
  });
});

答案 0 :(得分：0)

我这样做是这样的：即仅在Mixpanel中开火production。

login.component.ts 

import { Component, OnInit, isDevMode } from "@angular/core";

ngOnInit() {
    if (!isDevMode()) Mixpanel.trackEvent("View Screen", { "Screen Name": "Login" });
    this.createForm();
  }
