使用Appium（java）+ Cucumber + jUnit在Browserstack上运行并行测试

Question

使用Browserstack教程（https://www.browserstack.com/app-automate/appium-junit）和示例项目（https://github.com/browserstack/junit-appium-app-browserstack），我在并行测试的设置上很挣扎。

特别是，我需要使用Cucumber.class（@RunWith(Cucumber.class)）运行suirte，以便从场景中读取我的测试，而Browserstack文档告诉我要使用Parameterized.class（public class Parallelized extends Parameterized）运行。如果使用Cucumber类运行套件，我遇到的最大问题是如何将多个device + os配置解析到Browserstack。

我的跑步者课程：

package step_definitions;

import org.junit.runner.RunWith;
import io.cucumber.junit.CucumberOptions;
import io.cucumber.junit.Cucumber;

@RunWith(Cucumber.class)
@CucumberOptions(features = {
        "src/main/resources/FeatureFiles" }, dryRun = false, strict = false, monochrome = true, plugin = {
                "html:target/cucumber", "json:target/cucumber.json" },
        // glue = {"iOSAutomation/src/test/java/step_definitions"},

        tags = { "@Login"})

public class RunTest {

}

启动器：

package step_definitions;

import (...)

public class Launcher {

    public static IOSDriver<IOSElement> driver;
    public static WebDriverWait wait;

    // Parallel BS tests
    private static JSONObject config;

    @Parameter(value = 0)
    public static int taskID;

    @Parameters
    public static Iterable<? extends Object> data() throws Exception {
        List<Integer> taskIDs = new ArrayList<Integer>();

        if (System.getProperty("config") != null) {
            JSONParser parser = new JSONParser();
            config = (JSONObject) parser.parse(new FileReader("src/main/resources/conf/" + System.getProperty("config")));
            int envs = ((JSONArray) config.get("environments")).size();

            for (int i = 0; i < envs; i++) {
                taskIDs.add(i);
            }
        }       

        return taskIDs;
    }

    @Before

    public static void Launchapp(Scenario scenario) throws InterruptedException, FileNotFoundException, IOException, ParseException {

        JSONArray envs = (JSONArray) config.get("environments");

        DesiredCapabilities caps = new DesiredCapabilities();

            caps.setCapability(MobileCapabilityType.AUTOMATION_NAME, "xcuitest");
            caps.setCapability(MobileCapabilityType.PLATFORM_NAME, "iOS");
            caps.setCapability("bundleId", bundleId);
            caps.setCapability(MobileCapabilityType.APP, "useNewWDA");
            caps.setCapability(MobileCapabilityType.APP, "clearSystemFiles");
            caps.setCapability(MobileCapabilityType.APP, app);
            caps.setCapability("browserstack.local", "false");
            caps.setCapability("webkitResponseTimeout", "60000");
            caps.setCapability("browserstack.localIdentifier", "Test123");
            caps.setCapability("browserstack.appium_version", "1.9.1");
            caps.setCapability("startIWDP", true);
            caps.setCapability("instrumentApp", true);
            caps.setCapability("webkitResponseTimeout", 70000);

            Map<String, String> envCapabilities = (Map<String, String>) envs.get(taskID);
            Iterator it = envCapabilities.entrySet().iterator();
            while (it.hasNext()) {
                Map.Entry pair = (Map.Entry) it.next();
                caps.setCapability(pair.getKey().toString(), pair.getValue().toString());
            }

            driver = new IOSDriver<IOSElement>(
                    new URL("http://" + userName + ":" + accessKey + "@hub-cloud.browserstack.com/wd/hub"), caps);

            sessionId = driver.getSessionId().toString();


        driver.manage().timeouts().implicitlyWait(60, TimeUnit.SECONDS);
        wait = new WebDriverWait(driver, 30);

    }

    @After
    public void tearDown(Scenario scenario) throws Exception {
        driver.quit();
    }


}

Parallelized.java：

package step_definitions;

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.TimeUnit;

import org.junit.runners.Parameterized;
import org.junit.runners.model.RunnerScheduler;

import io.cucumber.junit.Cucumber;

public class Parallelized extends Parameterized {

  private static class ThreadPoolScheduler implements RunnerScheduler {
    private ExecutorService executor; 

    public ThreadPoolScheduler() {
      String threads = System.getProperty("junit.parallel.threads", "4");
      int numThreads = Integer.parseInt(threads);
      executor = Executors.newFixedThreadPool(numThreads);
    }

    @Override
    public void finished() {
      executor.shutdown();
      try {
        executor.awaitTermination(10, TimeUnit.MINUTES);
      } catch (InterruptedException exc) {
        throw new RuntimeException(exc);
      }
    }

    @Override
    public void schedule(Runnable childStatement) {
      executor.submit(childStatement);
    }
  }

  public Parallelized(Class klass) throws Throwable {
    super(klass);
    setScheduler(new ThreadPoolScheduler());
  }
}

和配置文件：

{
  "environments": [{
    "device": "iPhone XR",
    "os_version": "12"
  }, {
    "device": "iPhone 6S",
    "os_version": "11"
  }, {
    "device": "iPhone XS",
    "os_version": "13"
  }, {
    "device": "iPhone XS Max",
    "os_version": "12"
  }]
}

如何使其运作？我可以使用Cucumber.class运行它，并以某种方式合并Parallelized.java中的方法吗？

您可以使用MakeFile来提供所有设备或平台的功能，并且使用cumcum-jvm-parallel-plugin可以在Browserstack中并行运行测试。这将是最简单的解决方案。

示例MakeFile：

browserstack_parallel：使-j bs_iPhoneXS bs_iPhoneX

bs_iPhoneXS：mvn test -Dbs_local_testing = false -Dbs_device = iPhoneXS -Dbs_app = bs：// 0fb247cde17a979db4d7e5a521bc600af7620b63

bs_iPhoneX：mvn test -Dbs_local_testing = false -Dbs_device = iPhoneX -Dbs_app = bs：// 0fb247cde17a979db4d7e5a521bc600af7620b63
