iOS: Earlgrey/Detox 错误运行相同的测试两次

Question

运行相同的测试两次都失败了。

重现步骤：

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);
  });
});

对可能出现的问题有什么想法吗？

Answer 1

按照要求以答案形式发布此问题。抱歉耽搁了。

尝试在使用 .typeText() 之前使用 .tap()。

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

Answer 2

确保您已激活键盘我遇到了这个问题。

在模拟器上单击时，在输入点击时切换键盘。
