Swift UI Testing Access string in the TextField

Question

I am using the UI Test Case class integrated in Xcode and XCTest to test app UI. I want to test something like this:

app = XCUIApplication() let textField = app.textFields["Apple"] textField.typeText("text_user_typed_in") XCTAssertEqual(textField.text, "text_user_typed_in") 

I've tried the textField.value as! String method; it does not work. I've also tried using the new async method with expectationForPredicate(), and it will result in a timeout.

Any idea how to do this or validation of this kind is not possible with UI Test and I could only write black-box tests?

Answer 1

I use this code and it works fine:

textField.typeText("value") XCTAssertEqual(textField.value as! String, "value") 

If you're doing something similar and it isn't functioning, I would check to make sure that your textField element actually exists:

XCTAssertTrue(textField.exists, "Text field doesn't exist") textField.typeText("value") XCTAssertEqual(textField.value as! String, "value", "Text field value is not correct")

Swhift 4.2. You need to clear an existing value in textField and paste new value.

let app = XCUIApplication() let textField = app.textFields["yourTextFieldValue"] textField.tap() textField.clearText(andReplaceWith: "VALUE") XCTAssertEqual(textField.value as! String, "VALUE", "Text field value is not correct") 

where clearText is a method of XCUIElement extension:

extension XCUIElement {     func clearText(andReplaceWith newText:String? = nil) {         tap()         press(forDuration: 1.0)         var select = XCUIApplication().menuItems["Select All"]          if !select.exists {             select = XCUIApplication().menuItems["Select"]         }         //For empty fields there will be no "Select All", so we need to check         if select.waitForExistence(timeout: 0.5), select.exists {             select.tap()             typeText(String(XCUIKeyboardKey.delete.rawValue))         } else {             tap()         }         if let newVal = newText {             typeText(newVal)         }     } }
