为登录Facebook的Android应用程序编写测试：UIAutomator无法填写Facebook用户名字段中的文本 [英] Writing tests for an android app that logs into Facebook: UIAutomator can't fill in text in Facebook's username field
问题描述
我没有尝试这个反对Facebook登录页面，但是我可以在我创建的另一个页面上执行此操作。
我可以使用UIObject和UIObject2来定位一个输入框使用EditText类的Web表单。我能够使用setText（）在输入框中设置文本，但是我无法使用getText（）读取它。
选择HTML输入表格需要谨慎。您可以可靠地选择特定输入的唯一方法是使用 instance（）找到第n个索引字段。这意味着您应该将搜索范围限制在WebView父对象中（否则屏幕上的其他EditText可能会抵消所有内容）。
另一件您需要注意是WebView的加载时间。这不会立即发生，所以你需要等待一些合理的时间来让页面加载。
这里有一些示例代码让我找到HTML页面上的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）;
From this question/answer I got the idea to use UIAutomator to test my app that requires logging into Facebook.
Writing tests for an Android app that logs into Facebook
I tried
UiObject2 editText = mDevice.findObject(By.clazz("android.widget.EditText"));
editText.setText("test@email.com");
As well as other things but whatever I do I can't get it to fill out the field. I used hierachyviewer tool to see that it was an EditText. It's a webview, though, so I don't know.
Is this possible?
My full test code class is attached below:

Edit: I actually used uiautomatorviewer not hierachyviewer. Here's a screenshot showing it's an edit text. At least according to this tool.
I didn't try this against a Facebook login page, but I was able to do this on a different page I created.
I was able to use both UIObject and UIObject2 to location an input box in a web form using the EditText class. I was able to both to set the text in the input box using setText(), but I was not able to read it out with getText().
Selecting HTML input forms requires some care. The only way you can reliably select a specific input is by using instance() to find the n'th indexed field. This means you should probably be limiting the scope of your searches to the WebView parent object (otherwise some other EditText on the screen might offset everything).
Another thing you need to look out for is the load time of the WebView. It's not going to happen instantaneously, so you will need to wait some reasonable amount of time to let the page load.
Here is a bit of sample code that let me find the second input box on a HTML page and put text into it:
UiObject input = mDevice.findObject(new UiSelector()
.instance(1)
.className(EditText.class));
input.setText("text");
