I would like to write a UI test in Xcode covering a login with FBDSKLoginKit
.
However, Facebook iOS SDK uses SFSafariViewController
presented to the user in order to authenticate her and unfortunately, there's no way how to interact with SFSafariViewController
in UI tests in Xcode 7.
Any ideas how to test the facebook login without interacting with SFSafariViewController
?
Swift 3 Xcode 8 solution
func testFacebookLogin() {
let app = XCUIApplication()
// set up an expectation predicate to test whether elements exist
let exists = NSPredicate(format: "exists == true")
// as soon as your sign in button shows up, press it
let facebookSignInButton = app.buttons["Login With Facebook"]
expectation(for: exists, evaluatedWith: facebookSignInButton, handler: nil)
facebookSignInButton.tap()
// wait for the "Confirm" title at the top of facebook's sign in screen
let confirmTitle = app.staticTexts["Confirm"]
expectation(for: exists, evaluatedWith: confirmTitle, handler: nil)
// create a reference to the button through the webView and press it
let webView = app.descendants(matching: .webView)
webView.buttons["OK"].tap()
// wait for your app to return and test for expected behavior here
self.waitForExpectations(timeout: 10, handler: nil)
}
Extension:
extension XCUIElement {
func forceTap() {
if self.isHittable {
self.tap()
} else {
let coordinate: XCUICoordinate = self.coordinate(withNormalizedOffset: .zero)
coordinate.tap()
}
}
}
Tested and verified to work great!
Swift 3 Xcode 8 update
func testFacebookLogin() {
let app = XCUIApplication()
// set up an expectation predicate to test whether elements exist
let exists = NSPredicate(format: "exists == true")
// as soon as your sign in button shows up, press it
let facebookSignInButton = app.buttons["Login With Facebook"]
expectation(for: exists, evaluatedWith: facebookSignInButton, handler: nil)
facebookSignInButton.tap()
// wait for the "Confirm" title at the top of facebook's sign in screen
let confirmTitle = app.staticTexts["Confirm"]
expectation(for: exists, evaluatedWith: confirmTitle, handler: nil)
// create a reference to the button through the webView and press it
let webView = app.descendants(matching: .webView)
webView.buttons["OK"].tap()
// wait for your app to return and test for expected behavior here
self.waitForExpectations(timeout: 10, handler: nil)
}
Extension:
extension XCUIElement {
func forceTap() {
if self.isHittable {
self.tap()
} else {
let coordinate: XCUICoordinate = self.coordinate(withNormalizedOffset: .zero)
coordinate.tap()
}
}
Swift 2
func testFacebookLogin()
{
let app = XCUIApplication()
// set up an expectation predicate to test whether elements exist
let exists = NSPredicate(format: "exists == true")
// as soon as your sign in button shows up, press it
let facebookSignInButton = app.buttons["Sign in with Facebook"]
expectationForPredicate(exists, evaluatedWithObject: facebookSignInButton, handler: nil)
facebookSignInButton.tap()
// wait for the "Confirm" title at the top of facebook's sign in screen
let confirmTitle = app.staticTexts["Confirm"]
expectationForPredicate(exists, evaluatedWithObject: confirmTitle, handler: nil)
// create a reference to the button through the webView and press it
var webView = app.descendantsMatchingType(.WebView)
webView.buttons["OK"].tap()
// wait for your app to return and test for expected behavior here
}
In my case, I also had to deal with the Assertion Failure: UI Testing Failure - Unable to find hit point for Button error via the forceTap() extension:
extension XCUIElement {
func forceTap() {
if self.hittable {
self.tap()
} else {
let coordinate: XCUICoordinate = self.coordinateWithNormalizedOffset(CGVectorMake(0.0, 0.0))
coordinate.tap()
}
}
}
