如何在 XCTest 和 XCUITest 中检查空 TextField

Question

I have to check if there is any UITextField is empty or contains any value using XCUITest or XCTest . I was checking on many places and found textField.Value can be used to find out the result. But for me the problem is textField.value returns placeholder as value and hence it fails to detect empty field as empty.

Answer 1

You have two cases to figure out wheter the textfield is empty. First one - Use standart bool value of yourTextField.text == nil and second check for the instance to have string of "" -> This should for instance occur when user would write some text and then delete it...

So in code:

// The second condition will occur only if the text is not nil, so 
// it is okay to unwrap it like it.
 XCTAssertTrue(textField.text == nil || textField.text!.isEmpty)

Answer 2

There is a solution which should work (apart from in one situation*). XCUIElement has a property placeholderValue , which should contain the text field's placeholder text. So try this:

let textfield = XCUIApplication().textFields["textFieldIdentifier"]

if let textFieldText = textField.value as? String,
   textFieldText.isEmpty == false,
   textFieldText != textField.placeholderValue {
    // Do the thing that requires the text field *not* to be empty
}

* The one scenario where this won't work is if the text entered in the text field is the same as the placeholder's text. Then we're in Failsville.

However, as this is a UITest, I would think you should have some control over what gets entered into this text field.

I ran into this recently and as pointed out by @adamjansch for UITextField the XCUIElement will return the placeholder value if it is set and there is no text in the text field.

Given that, I ended up doing something like this:

let query = app.scrollViews.otherElements
let textField = query.textFields["textFieldIdentifier"]

if textField.value != nil,
   let aValue = textField.value as? String,
   let placeholderValue = textField.placeholderValue,
   aValue != placeholderValue

{
   // Do something with the text field; it has a value
   // so perhaps it needs to be cleared before a new
   // value is input.
   textField.buttons["Clear text"].tap()
}
else
{
    ...
}

There is a workaround for your problem. If you dont want to get the placeholder

• First click on the textfield

  textField.tap()

• Get the value from the textfield element

  let pageTitle = textField.value as? String var titleLength = pageTitle?.characters.count XCTAssertTrue(titleLength==0, "Title is empty")
