Question

我正在尝试使用appium和selenium网格运行一些移动自动化测试。完成所有配置并添加网格节点后，如何在两个设备中并行运行测试？

这是我的setUp()：

desired_caps = {}
    desired_caps['platformName'] = 'Android'
    desired_caps['platformVersion'] = '5.1'
    desired_caps['deviceName'] = ''
    desired_caps['app'] = os.path.abspath(os.path.join(os.path.dirname(__file__), 'C:/Users/XXXXX/Desktop/workspace/XXXX/apps/XXXXX.apk'))
    desired_caps['appPackage'] = 'XXXXXXXX'
    desired_caps['appActivity'] = '.MainActivity'
    desired_caps['noReset'] = False
    self.driver = webdriver.Remote('http://localhost:4444/wd/hub', desired_caps)
    self.driver.implicitly_wait(15)

在这种情况下，deviceName应该是什么？

如果我把它留空，这就是我得到的：

C:\Users\XXXXX\Desktop\workspace\XXXXX>java -jar selenium-server-standalone-2.44.0.jar -role hub

我只能在网格中运行一个注册节点。我甚至尝试使用two setup()创建一个脚本，每个脚本都放在每个设备上，但即使这样，测试也仅在同一个设备中运行一个设备。

这是我的网格控制台：

    I did try to run tests using Grid with Appium server in java, same logic you can adopt for your own language. Here is the explanation:

    1. This is the same content of node.json file on two node machines:

    {
    "capabilities":
         [
           {
             "version":"4.4.2",
             "maxInstances": 3,
             "platformName":"ANDROID"
           }
         ],
    "configuration":
    {
       "cleanUpCycle":2000,
       "timeout":30000,
       "proxy": "org.openqa.grid.selenium.proxy.DefaultRemoteProxy",
       "url":"http://WHERE_APPIUM_RUNNNING:4723/wd/hub",
       "host": "WHERE_APPIUM_RUNNNING_IP",
       "port": 4723,
       "maxSession": 6,
       "register": true,
       "registerCycle": 5000,
       "hubPort": 4444,
       "hubHost": "WHERE_HUB_RUNNNING_IP"
    }
    } 

    2. Downloaded selenium-server-standalone-2.52.0.jar and started as hub on one machine like: 
    java -jar ~/Downloads/selenium-server-standalone-2.52.0.jar -role hub maxInstances=2 maxSessions=2 

    3. Started ONLY appium server on node machines and registered with hub using command as: appium --nodeconfig ~/Desktop/node.json

    4. Now declare all the common capability in GridTest.java and only deviceName was passed from testNG.xml in order to avoid any hardcoding in code and keeping node.config as generic for all node machines, sample testNG.xml is like:

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
    <suite name="Automation" parallel="tests">

        <test name="Test1">
        <parameter name="deviceName" value="XYZZZZZ" />
            <classes>
                <class name="poc.grid.GridTest" />
            </classes>
        </test>

        <test name="Test2">
        <parameter name="deviceName" value="ZYXXXXX" />
            <classes>
                <class name="poc.grid.GridTest" />
            </classes>
        </test>

    </suite>

    5. And I wrote a GridTest.java class like:

    package poc.grid;
    import java.net.MalformedURLException;
    import java.net.URL;
    import java.util.concurrent.TimeUnit;

    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.remote.DesiredCapabilities;
    import org.openqa.selenium.remote.RemoteWebDriver;
    import org.testng.annotations.Parameters;
    import org.testng.annotations.Test;


    public class GridTest {

        @Parameters({"deviceName"})
        @Test
        public void test (String deviceName) throws MalformedURLException, InterruptedException
        {
            appium_driver(deviceName);
        }

        public void appium_driver(String deviceName)
        {
            try
            {
                DesiredCapabilities capabilities = new DesiredCapabilities();
                capabilities.setCapability("deviceName", deviceName);
                capabilities.setCapability("platformName", "Android");

                if(deviceName.equalsIgnoreCase("4d0025b440ca90d5")){
                    capabilities.setCapability("app", "/XXXXXX/chocolate.apk");
                }else{
                    capabilities.setCapability("app", "/XXXXXX/chocolate.apk");
                }

                capabilities.setCapability("newCommandTimeout", "120");
                WebDriver driver = new RemoteWebDriver(new URL("http://WHERE_HUB_RUNNNING_IP:4444/wd/hub"), capabilities);

                driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
            }
            catch(Exception e)
            {
                System.out.println(e.getMessage());
                e.printStackTrace();
            }
        }
    }


6. If you are using eclipse, then Right Click on testNG.xml and select Run As --> TestNg Suite.

7. Now you can see I've kept a condition only for apk file location because the node machines have different directory, if possible you should choose a similar location which exists in all node machines, else you may have to live with if - else.  Hope This Helps !!

从我收集的内容中，您尝试同时运行测试，对吧？

如果是这样，我在帖子中没有看到任何关于线程的内容，没有线程，你的测试将连续运行。

Selenium Grid不会为同类资源进行循环连接。它只是分配第一台可用的机器。 I.E.如果测试'A'请求特定的浏览器/平台/设备配置，并运行完成，那么如果测试'B'出现并要求相同的配置，它将获得测试A得到的相同机器。有意义吗？

如果您想并行测试，我建议您查看pytest＆amp; xdist插件。这将为您处理所有线程/多进程内容。

有趣的是，即使您编写了所有使用unittest的内容，也不必重写所有内容以使用pytest;只需在现有代码中指向pytest。

使用appium和selenium网格运行自动化测试只能在一台设备上运行
