iOS - 在 UITests 目标中使用推送通知

Question

我需要在 AppUITests 中使用推送通知。有什么方法可以使用自定义授权文件添加/更新 AppUITests 目标的设置吗？

Answer 1

在 Xcode 9 中，您可以使用名为 NWPusher 的框架在 UITest 中使用远程通知。

要在您的 UITest 中测试远程通知，您必须执行以下步骤:

1. 将 NWPusher 添加到您的 UITest 目标
2. 从 Apple 的开发中心下载 APN 开发证书并将其添加到您的钥匙串(keychain)(如果尚不存在)
3. 将证书导出为 p12 文件
4. 编写测试

我试过了，这是我的测试文件:

我的演示应用程序根据收到的推送通知呈现三个不同的模态视图 Controller 。所以本次测试有3种不同的推送通知。

import XCTest
import PusherKit

class PushNotificationUITests: XCTestCase {

    override func setUp() {
        super.setUp()
        continueAfterFailure = false
    }

    func testPushNotifications() {
        let app = XCUIApplication()
        app.launchArguments.append("isRunningUITests")
        app.launch()

        // access to the springboard (to be able to tap the notification later)
        let springboard = XCUIApplication(bundleIdentifier: "com.apple.springboard")

        // dismiss the system dialog if it pops up
        allowPushNotificationsIfNeeded()

        // get the current deviceToken from the app
        let deviceToken = app.staticTexts.element(matching: .any, identifier: "tokenLabel").label

        // close app
        XCUIDevice.shared.press(XCUIDevice.Button.home)
        sleep(1)

        // trigger red Push Notification
        triggerPushNotification(
            withPayload: "{\"aps\":{\"alert\":\"Hello Red\"}, \"vcType\":\"red\"}",
            deviceToken: deviceToken)

        // tap on the notification when it is received
        springboard.otherElements["PUSHNOTIFICATION, now, Hello Red"].tap()

        // check if the red view controller is shown
        XCTAssert(app.staticTexts["Red"].exists)

        // dismiss modal view controller and close app
        app.buttons["Close"].tap()
        XCUIDevice.shared.press(XCUIDevice.Button.home)
        sleep(1)

        // trigger green Push Notification
        triggerPushNotification(
            withPayload: "{\"aps\":{\"alert\":\"Hello Green\"}, \"vcType\":\"green\"}",
            deviceToken: deviceToken)

        // tap on the notification when it is received
        springboard.otherElements["PUSHNOTIFICATION, now, Hello Green"].tap()

        // check if the green view controller is shown
        XCTAssert(app.staticTexts["Green"].exists)

        // dismiss modal view controller and close app
        app.buttons["Close"].tap()
        XCUIDevice.shared.press(XCUIDevice.Button.home)
        sleep(1)

        // trigger blue Push Notification
        triggerPushNotification(
            withPayload: "{\"aps\":{\"alert\":\"Hello Blue\"}, \"vcType\":\"blue\"}",
            deviceToken: deviceToken)

        // tap on the notification when it is received
        springboard.otherElements["PUSHNOTIFICATION, now, Hello Blue"].tap()

        // check if the blue view controller is shown
        XCTAssert(app.staticTexts["Blue"].exists)

        // dismiss modal view controller 
        app.buttons["Close"].tap()
    }
}

extension XCTestCase {
    func triggerPushNotification(withPayload payload: String, deviceToken: String) {
        let uiTestBundle = Bundle(for: PushNotificationUITests.self)
        guard let url = uiTestBundle.url(forResource: "pusher.p12", withExtension: nil) else { return }

        do {
            let data = try Data(contentsOf: url)
            let pusher = try NWPusher.connect(withPKCS12Data: data, password: "pusher", environment: .auto)
            try pusher.pushPayload(payload, token: deviceToken, identifier: UInt(arc4random_uniform(UInt32(999))))
        } catch {
            print(error)
        }
    }

    func allowPushNotificationsIfNeeded() {
        addUIInterruptionMonitor(withDescription: "“RemoteNotification” Would Like to Send You Notifications") { (alerts) -> Bool in
            if(alerts.buttons["Allow"].exists){
                alerts.buttons["Allow"].tap();
            }
            return true;
        }
        XCUIApplication().tap()
    }
}
