Testing if an element is visible with Xcode 7 UITest

问题

I want to verify if an element is visible or not depending on its .hidden property but I don't find a valid way to do that using the new Xcode 7 UI test stuff.

I've tried with myelement.exists and myelement.hittable but they doesn't seems to work as I expected. I suppose they work on conjunction with the hidden property. An hidden element shouldn't exists and is not hittable... but this is not the current behaviour (I can understand the exists behaviour... but a hidden element should be not hittable IMO).

Is there another way to verify the "hidden" property value?

回答1:

As of Xcode 7.1 Beta 3, UI Testing does not currently support validating the visibility of an element. I suggest filing a radar to bring the necessary attention to Apple.

Xcode 7.1 has fixed this issue. hittable now checks to see if the element is correct.

1) I am testing the UI with swift in Xcode 7.3 and I using both .hittable and .exists for testing whether a label is hidden or not and they both work. I test for 'true' and 'false' to make sure either way agree with the result.

I have a label whose static text is "Track Info" and set to be hidden when app is first loaded, then later on I press a button to show the label, and here is the result after the label is shown.

// test fails

let trackInfoLabel = app.staticTexts["Track info"]
XCTAssertEqual(trackInfoLabel.exists, true)

XCTAssertEqual(trackInfoLabel.hittable, true)

// test passes

XCTAssertEqual(trackInfoLabel.exists, false)
XCTAssertEqual(trackInfoLabel.hittable, false)

// test passes

let trackInfoLabel = app.staticTexts["Track Info"]
XCTAssertEqual(trackInfoLabel.exists, true)

XCTAssertEqual(trackInfoLabel.hittable, true)

// test fails

XCTAssertEqual(trackInfoLabel.exists, false)
XCTAssertEqual(trackInfoLabel.hittable, false)

Leter on when I press the button to hide the label, all the results turned opposite. This confirms that both properties (hittable and exists) works for label.hidden setting.

2) Another way to find out if an element is hidden, you can do is element.frame.size.width == 0 || element.frame.size.height == 0

XCUIElement.hittable works for me (in my particular test case where I am checking several UIButton elements for visibility) - quite sure it is not a right way to do it though

回答4:

Next code worked for me. At the end of the test you can past code as follow:

while ([app.staticTexts matchingIdentifier:@"accesibilityId"].count > 0) {
        sleep(1);
    }

I agree hittable doesn't always work for buttons (Swift 2.0, XCode 7.2)

I just discovered that if button is visible, you can find it ONLY among buttons, while if button is hidden, you can find it's tag in staticTexts as well!

XCTAssertFalse(app.buttons["Log out"].exists && app.staticTexts["Log out"].exists) // This button is visible (hidden = false)
XCTAssert(app.buttons["Log in"].exists && app.staticTexts["Log in"].exists) // This one is hidden

Hacky, but works for buttons. Apple should just introduce .hidden or .visible along .hittable and .exists

My solution is to add accessibilityIdentifier dynamicly

func someMethod() {
    label.isHidden = true
    label. accessibilityIdentifier = "isHidden"
}

func someOtherMethod {
    label.isHidden = false
    label. accessibilityIdentifier = "isVisible"
}

and the in UITest you can use it as

if app.staticTexts["MyLabel"].identifier == "isHidden" {
    dosomething()
}
