appium 的此会话问题不支持定位器策略“css 选择器" [英] Locator Strategy 'css selector' is not supported for this session issue with appium

问题描述

由于我是移动自动化的新手，我一直在尝试使用 appium maven 和 eclipse 运行简单的活动.但是当我尝试运行计算器应用程序时打开但无法访问元素.

Since I'm new to mobile automation, I've been trying to run simple activities using appium maven and eclipse. But When I try to run Calculator app opens but the elements are not accessible.

这是我用来运行一个简单计算器的代码

This the code I used to run a simple calculator

  @BeforeClass
 public void setUp() throws MalformedURLException {

    DesiredCapabilities capabilities = new DesiredCapabilities();
    capabilities.setCapability("BROWSER_NAME", "Android");
    capabilities.setCapability("VERSION", "4.4.2");
    capabilities.setCapability("deviceName", "Emulator");
    capabilities.setCapability("platformName", "Android");

    capabilities.setCapability("appPackage", "com.android.calculator2");

    capabilities.setCapability("appActivity", "com.android.calculator2.Calculator");

    driver = new RemoteWebDriver(new URL("http://0.0.0.0:4723/wd/hub"), capabilities);
}

@Test
public void testCal() throws Exception {

    WebElement two = driver.findElement(By.name("2"));
    two.click();

}

@AfterClass
public void teardown() {

}

我使用的是最新的稳定依赖项.io.appium java-client 7.0.0 和org.testng testng 6.14.3

I am using the latest stable dependencies. io.appium java-client 7.0.0 and org.testng testng 6.14.3

推荐答案

Appium 不是 Selenium:它们都使用 JSON 线协议实现并且具有相似的 API，但不相同:

Appium is not Selenium: they both implemented using JSON wire protocol and has similar APIs, but not the same ones:

原生安卓应用支持的定位器策略:

Supported locator strategies for Native android app:

• id (resource-id View 属性);
• accessbilityId(content-desc 视图属性)；
• uiAutomator(最好阅读UiSelector)；
• className (ui 组件类型);
• XPath.

因此您不能对 Android 驱动程序会话使用 By.name 定位器策略，它不受支持.

So you cannot use By.name locator strategy for Android driver session, it's not supported.

为了简单起见，我建议在 Appium 原生测试中使用 MobileBy 代替 By:您将获得正确的选项.

To make it easy, I suggest using MobileBy in place of By in Appium native tests: you will get the proper options.
