我正在使用test ng并行运行测试用例，但是无法从步骤定义类中获取参数。有人知道我该如何实现吗？目前正在黄瓜 @注解之前，我得到这个异常。如果我使用@BeforeTest / @BeforeClass（测试ng注释）而不是@Before代码，则不会执行任何操作（不会检测到该注释）

答案 0 :(得分：0)
使用以下代码：
public class StartPageSteps{
AndroidDriver<MobileElement> androidDriver;
String USERNAME = "";
String ACCESS_KEY = "";
String url = "https://" + USERNAME + ":" + ACCESS_KEY + "@hub.browserstack.com/wd/hub";
String pVersion;
@Before
public void setUp(){
System.out.println("Inside Setup");
}
@Parameters({"deviceName", "platformVersion"})
public void init(String deviceName,String platformVersion){
System.out.println(deviceName + " : " + platformVersion);
}
public StartPageSteps(){
}
}

让我们理解为什么您会遇到此异常...
拇指规则- 您不能在@Before（挂钩）内部传递超过1个参数，而该参数是从cumul.api.java.Before调用的。
您应使用@BeforeTest（org.testng.annotations.BeforeTest）而不是使用@Before
