【问题描述】：

两次运行相同的测试第二次失败。

复制步骤：

此测试通过：

describe('Login', () => 
  beforeEach(async () => 
    await device.reloadReactNative();
  );

  it('should not login', async () => 
    await waitFor(element(by.id('welcome')))
      .toBeVisible()
      .withTimeout(5000);

    await element(by.id('EmailField')).clearText();
    await element(by.id('EmailField')).typeText('wronggmail.com');
    await element(by.id('PasswordField')).clearText();
    await element(by.id('PasswordField')).typeText('wrongpass');

    await element(by.id('LoginButton')).tap();

    await waitFor(element(by.id('Home')))
      .toBeNotVisible()
      .withTimeout(10000);
  );
);

这失败了：

describe('Login', () => 
  beforeEach(async () => 
    await device.reloadReactNative();
  );

  it('should not login', async () => 
    await waitFor(element(by.id('welcome')))
      .toBeVisible()
      .withTimeout(5000);

    await element(by.id('EmailField')).typeText('wronggmail.com');
    await element(by.id('PasswordField')).typeText('wrongpass');

    await element(by.id('LoginButton')).tap();

    await waitFor(element(by.id('Home')))
      .toBeNotVisible()
      .withTimeout(10000);
  );

  it('should not login', async () => 
    await waitFor(element(by.id('welcome')))
      .toBeVisible()
      .withTimeout(5000);

    await element(by.id('EmailField')).typeText('wronggmail.com');
    await element(by.id('PasswordField')).typeText('wrongpass');

    await element(by.id('LoginButton')).tap();

    await waitFor(element(by.id('Home')))
      .toBeNotVisible()
      .withTimeout(10000);
  );
);

关于可能是什么问题的任何想法？

【问题讨论】：

不太确定这个但是如何等待该字段在失败的测试中可见：await expect(element(by.id('EmailField'))).toBeVisible();或者在使用 .typeText() 之前尝试使用 .tap()。

@Nemoverflow 就是这样！键盘做了一些奇怪的事情。在typeText() 工作之前做.tap()！非常感谢:)

@Nemoverflow 您介意将其发布为答案以便解决此问题吗？

【参考方案1】：

按照要求以答案形式发布此问题。抱歉耽搁了。

在使用 .typeText() 之前尝试使用 .tap()。

[...]
await expect(element(by.id('EmailField'))).toBeVisible();
await element(by.id('EmailField')).tap();
[...]

【参考方案2】：

确保您已激活键盘 我遇到了这个问题。

在模拟器上点击时，在输入点击时切换键盘。
