How to access back bar button item in universal way under UITests in Xcode?

Question

The problem is when I try to access back bar button item because it is presented with:

• Restaurants title,
• Back title
• without title

Like it is on the screens:

Currently I access it like this:

let backButton = XCUIApplication().buttons["Restaurants"]

but it won't work for other cases. It is not universal way. May I somehow set it accessibilityIdentifier or something else?

Answer 1

Generally the back button tends to be the first button element in the navigation bar

app.navigationBars.buttons.element(boundBy: 0).tap()

Answer 2

Based on Aaron Sofaers comment, you can also set the accessibilityIdentifier directly in Interface Builder.

Answer 3

Here's how you can do it in Swift 3:

app.navigationBars.buttons.element(boundBy: 0).tap()
