ios – 如何在Xcode中编写覆盖Facebook登录的UI测试？

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)        
}

延期：

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！
