TestCafe 跳过点击步骤

如何解决TestCafe 跳过点击步骤

成功通过身份验证，但我不明白为什么，出于某种原因跳过单击下拉菜单并突然关闭浏览器窗口。

谁能知道为什么测试会跳过单击此处的下拉菜单？

import LoginModel from './page-models/Login';
const url = 'http://localhost:5000';
fixture('Login tests - Logged In')
  .page(url)
  .beforeEach(async t => {
    await LoginModel.userLogin(t);
  });
  test('Should show the drop menu',async t => {
    await t.expect(LoginModel.dropMenu.exists).ok();
  });
test('Should show the logout button after logging in',async t => {
  await t.expect(LoginModel.logoutButton.exists).ok();
});
fixture('Login tests - Not logged in').page(url);
test('Should have a username and password field',async t => {
  await t.wait(10000);
  await t.expect(LoginModel.username.exists).ok();
  await t.expect(LoginModel.password.exists).ok();
});

页面对象模型：

class Login {
    username: Selector = Selector('[id=userEmail]');
    password: Selector = Selector('[id=userPassword]');
    loginButton: Selector = Selector('[id=login-button]');
    dropMenu: Selector = Selector('[id=simple-menu]');
    logoutButton: Selector = Selector('[id=logout-button]');
    async userLogin(t: TestController) {
      await t
        .typeText(this.username,'user',{ replace: true,paste: true })
        .typeText(this.password,'pass',paste: true })
        .click(this.loginButton);
    }
    async userClickDropMenu(t: TestController) {
      await t
        .click(this.dropMenu);
    }
    async userlogout(t: TestController) {
      await t
        .click(this.logoutButton);
    }
  }   
export default new Login();
