我正在使用Detox，并使用以下UI对tipsi-stripe软件包进行集成测试：

Credit Card Sample

我的测试如下：

    ...
    await expect(element(by.text('10'))).toBeVisible()
    await expect(element(by.text('Give $10'))).toBeNotVisible()
    await element(by.text('10')).tap()
    await expect(element(by.text('Give $10'))).toBeVisible()
    await expect(element(by.id('cc-card-input'))).toBeVisible()
    await element(by.id('cc-card-input')).typeText("4242424242424242")
    ...

最后一行失败：

  ● Signin › allows the person to make a payment

    Error performing 'Click to focus & type text (4242424242424242)' on view '(with tag value: is "cc-card-input" and view has effective visibility=VISIBLE)'.
    > 28 |     await element(by.id('cc-card input')).typeText("4242424242424242")

失败表明无法输入cc卡输入。

从相关库中获取组件：

您会看到testID被分配给TouchableWithoutFeedBack组件-而不是输入的组件。

我尝试过

  • 在NativePaymentCardTextField上设置testID
  • 设置accessible={true}，并在父组件上设置了accessibilityId

View Hierarchy from Detox

我在两者上都遇到相同的错误。

要在此组件中输入信用卡号（如果可能的话），我需要做些什么

谢谢。

从层次结构来看，似乎cc-card-input测试ID被分配给包装器而不是文本字段本身。特别是，本节显示：

（查看与CreditCardForm视图关联的标签）

在确实可见的情况下，您只能有效typeText()覆盖作为文本输入的视图（即，打开软键盘的位置）。

将测试ID重新定位到可以有效接受输入的视图即可解决它（我很难说哪个是根据层次结构确定的确切视图，因为视图似乎是自定义的。）
