記一次appium識別toast問題解決經歷

原文：http://blog.csdn.net/songer_xing/article/details/71272566

 

經查詢appium1.6.3以上才能識別toast，之前安裝appium版本是1.4.X,於是重整了測試環境，這篇后半部分有記錄appium環境搭建（Android）

官方文檔是這么說的

 

Firstly you should install appium server. Appium getting started. The version 1.6.3 or greater is recommended.

Since version 5.x there many features based on Java 8. So we recommend to install JDK SE 8 and provide that source compatibility.

也就是更新appium 到1.6.3以上，java-client版本最好是5.x，jdk要用1.8、selenium要用3.x，其他版本不一定兼容，要自己親測是否可用

根據要求重整環境如下：

appium：1.6.3

UiAutomator2 Drvier: 0.2.3

java-client ：5.0.0-BETA6

selenium：3.3.1

jdk：1.8

sdk：4.4.2

想識別toast，官網是這么說

 

capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.APPIUM);

You have to define this automation type to be able to use Android UIAutomator2 for new Android versions

capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);

我手機系統是6.0,sdk版本UIAutomator2，加上這句

capabilities.setCapability(MobileCapabilityType.AUTOMATION_NAME, AutomationName.ANDROID_UIAUTOMATOR2);

運行后手機會裝如下兩個apk

io.appium.uiautomator2.server
io.appium.uiautomator2.server.test

啟動driver代碼如下：

       protected AndroidDriver<WebElement> driver;

@Parameters({ "serverIP","port", "platformName","udid",
        "appPackage", "appActivity" })
@BeforeTest
public void setUp(String serverIP,String port,String platformName,String udid,
         String appPackage,String appActivity) throws Exception {
    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability(CapabilityType.BROWSER_NAME, "");
    capabilities.setCapability("platformName", platformName);
    capabilities.setCapability("deviceName", udid);
    capabilities.setCapability("udid", udid);
    capabilities.setCapability("platformVersion", "6.0");
    capabilities.setCapability("unicodeKeyboard", true);
    capabilities.setCapability("resetKeyboard", true);
    capabilities.setCapability("noReset", true);
    capabilities.setCapability("noSign", true);
    capabilities.setCapability("appPackage", appPackage);
    capabilities.setCapability("appActivity", appActivity);
    capabilities.setCapability("automationName","uiautomator2");//調用uiautomator2,獲取toast

    driver = new AndroidDriver(new URL("http://" + serverIP + ":" + port + "/wd/hub"),
            capabilities);
      }

識別toast代碼：

final WebDriverWait wait = new WebDriverWait(driver,3);
Assert.assertNotNull(wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath(".//*[contains(@text,'"+ toast + "')]"))));
log.info("查找toast成功！");
return true;
} catch (Exception e) {
throw new AssertionError("找不到"+toast);

運行后driver初始化失敗,也沒有裝如上所說的兩個apk，去掉這句

看這個報錯信息有點蒙，服務日志一句一句跟下來，發現這句

[MJSONWP] Encountered internal error running command: Error: Could not find zipa
lign.exe in tools, platform-tools, or supported build-tools under D:\andriod\and
roid-sdk-windows do you have the Android SDK installed at this location?

額，原來是sdk沒這個工具，沒辦法進行 Zip-aligning apk，然后安裝。所以報錯，很是欣喜，然后用360手機助手手動安裝了這兩個apk到手機，再次運行，一直在等待uiautomator2，最后超時報錯，說明uiautomator2 server沒起來

百度相關信息特別少，只能查官網，按官網所說我的配置，代碼都沒問題。查單元測試源碼，也證明這樣做是對的，后來懷疑，appium版本與java-client,selenium版本不兼容，前前后后換了好幾個版本，整了好幾天，還是不行，最后也排除了這幾個版本兼容性，最后更新了sdk,最高支持> POST /wd/hub/session/be19a6ec-33b4-49c2-a209-b6e7fd8ad9ce/elements {"

最后針對這次問題的解決過程，又做了重新梳理，最后得出結論是io.appium.uiautomator2.server、io.appium.uiautomator2.server.test這兩個apk,一定要進行Zip-aligning apk，然后再安裝，才能正常使用，手動安裝不行，跟sdk版本是否更新到6.0無直接關系，中間踩了好幾個坑，費了好幾天時間。大家可以借鑒一下，有什么問題，也可以留言，大家一起討論。
