为登录Facebook的Android应用程序编写测试：UIAutomator无法在Facebook的用户名字段中填写文本

Question

从这个问题/答案中我得到了使用UIAutomator测试我的应用程序需要登录Facebook的想法。

Writing tests for an Android app that logs into Facebook

我试过

        UiObject2 editText = mDevice.findObject(By.clazz("android.widget.EditText"));
        editText.setText("test@email.com");

和其他事情一样，但无论我做什么，我都无法填写这个领域。我使用hierachyviewer工具看到它是一个EditText。这是一个webview，所以我不知道。

这可能吗？

我的完整测试代码类如下：

编辑：我实际上使用的是uiautomatorviewer而不是hierachyviewer。这是一个屏幕截图，显示它是一个编辑文本。至少根据这个工具。

Answer 1

我没有在Facebook登录页面上尝试此操作，但我能够在我创建的其他页面上执行此操作。

我能够使用UIObject和UIObject2使用EditText类在Web表单中定位输入框。我能够使用setText（）在输入框中设置文本，但是我无法用getText（）读出它。

选择HTML输入表单需要一些注意。您可以可靠地选择特定输入的唯一方法是使用instance()来查找第n个索引字段。这意味着您可能应该将搜索范围限制为WebView父对象（否则屏幕上的其他一些EditText可能会抵消所有内容）。

您需要注意的另一件事是WebView的加载时间。它不会立即发生，因此您需要等待一段合理的时间才能让页面加载。

下面是一些示例代码，让我在HTML页面上找到第二个输入框并将文本放入其中：

UiObject input = mDevice.findObject(new UiSelector()
    .instance(1)
    .className(EditText.class));
input.setText("text");
