UITest cases to handle with location services alert - ios

Question

I am writing UI test cases for my project.
My project flow is as below:
Login Screen. User enters credentials and press login.
Home Screen. There is location requirement so system as for user's permission. I allow it.
Logout.
So when I do fresh install of application this flow is recorded in test case and works if I perform on new fresh build.
But problem is when I test on old build there is no alert for location permission and the test's gets fail. How can I handle this cases or ask user for permission every time when I run tests?
For resetting credentials of user I am passing launchArguments to XCUIApplication() and handle in AppDelegate.
I have implemented code let me know if its correct way:
addUIInterruptionMonitor(withDescription: "Allow “APP” to access your location?") { (alert) -> Bool in
alert.buttons["Only While Using the App"].tap()
return true
}
The above code works for both if alert comes or not.

Answer 1

Using an interruption monitor is the correct way. However, it's safer to check if the alert being displayed is the alert you're expecting before you interact with the alert:
addUIInterruptionMonitor(withDescription: "Allow “APP” to access your location?") { (alert) -> Bool in
let button = alert.buttons["Only While Using the App"]
if button.exists {
button.tap()
return true // The alert was handled
}
return false // The alert was not handled
}

Try this
let app2 = XCUIApplication(bundleIdentifier: "com.apple.springboard")
let button = app2.alerts.firstMatch.buttons["Allow While Using App"]
button.waitForExistence(timeout: 10)
button.tap()

Answer 3

I use the following code to allow user's location:
// MARK: - Setup
override func setUp() {
super.setUp()
continueAfterFailure = false
app = XCUIApplication()
app.launch()
addUIInterruptionMonitor(withDescription: "System Dialog") { (alert) -> Bool in
alert.buttons["Allow Once"].tap()
return true
}
}
In this setup, I "register" the interruption monitor for tapping the allow button, so in this case I can dismiss that modal. Now, there's my test:
// MARK: - Test change mall
func testChangeMall() {
let selectorChangeButton = app.buttons["change_mall_button"]
XCTAssert(selectorChangeButton.exists, "Selector change button does not exist")
selectorChangeButton.tap()
app.navigationBars.firstMatch.tap()
let cell = app.staticTexts["Shopping Centre"]
XCTAssert(cell.exists, "There's no cell with this title")
cell.tap()
sleep(1)
let label = app.staticTexts["Shopping Centre"]
XCTAssert(label.exists, "Nothing changes")
}
In this test, simply I go to a view controller with a list sorted by location. First, I need to dismiss the location's system alert. So, first I dismiss that modal and then I tap a cell from my TableView. Then, I need to show it in my main view controller so I dismiss my view controller and I expect the same title.
Happy Coding!
