ios - 如何在 Xcode 中编写涵盖使用 Facebook 登录的 UI 测试？

Question

我想在 Xcode 中编写一个 UI 测试，涵盖使用 FBDSKLoginKit 登录.

然而，Facebook iOS SDK uses SFSafariViewController呈现给用户以验证她的身份，不幸的是，there's no way how to interact with SFSafariViewController in UI tests in Xcode 7 .

有什么想法可以在不与 SFSafariViewController 交互的情况下测试 facebook 登录吗？

Swift 3 Xcode 8 解决方案

 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)        
}

扩展名:

extension XCUIElement {
    func forceTap() {
        if self.isHittable {
            self.tap()
        } else {
            let coordinate: XCUICoordinate = self.coordinate(withNormalizedOffset: .zero)
            coordinate.tap()
        }
    }
}

经过测试和验证，效果很好!
