Test tabbar badge via Xcode UI XCTests in iOS

Question

How to check that tabbar badge (tabBarItem.badgeValue) contains correct number in XCTests?

I can see target tabbar button in Accessibility Inspector, but badge element isn't inspectable.

Answer 1

You can set the accessibilityIdentifier value to the tab bar item.

tabBarItem.accessibilityIdentifier = "Your_Identifier"

On your UITest case,

guard let value = app.buttons["Your_Identifier"].value as? String 
else {
    XCTFail("badge value not updated")
    return
}
XCTAssert(value == "1 item", "badge value not updated")

The value will be in the format "number_on_badge item(s)". Thus in your case, you should be testing against "19 items".
