testng - 防止 TestNg 在并行测试之间共享数据

Question

目标:并行独立运行 2 个类，其中每个测试将方法名称存储到一个变量中，该变量稍后可以在测试中访问。

问题:当测试并行运行时，它们开始在它们之间共享数据，从而破坏测试。

如果您看到控制台输出这是错误的:

INFO: Name of Test from Before Method: classB_Method1
INFO: Name of Test from Before Method: classB_Method1

因为这是两个独立的类和正在运行的方法。和我在这里设置了正确的名称:

  !! Setting Method name to: classA_Method1
    !! Setting Method name to: classB_Method1  

输出应该是这样的:

INFO: Name of Test from Before Method: classA_Method1
INFO: Name of Test from Before Method: classB_Method1

测试A

import java.lang.reflect.Method;
import org.testng.annotations.*;
import com.xxxx.util.*;

public class TestA {


    @Test(/*dataProvider = "DP_MVPLoan_Login",*/ groups = {"parallel_test" }, invocationCount = 1, priority = 2, enabled = true)
    public void classA_Method1(/*String... excelData*/) throws Exception {

    }

    /////////////////////////////////////////////////////////////////////////////
    // ****SetUp and Tear Down

    @BeforeTest(alwaysRun=true)
    public void setupClass() throws Exception {
    }


    @BeforeMethod(alwaysRun=true)
    public void setupMethod(Method method) throws Exception {
        SeleniumHelperDebug.setCurrentMethodName(method.getName());
        SeleniumHelperDebug.defaultBeforeMethod(); 

    }

}

测试B

import java.lang.reflect.Method;
import org.testng.annotations.*;
import com.xxxx.util.*;

public class TestB {


@Test(/*dataProvider = "DP_MVPLoan_Login",*/ groups = { "parallel_test" }, invocationCount = 1, priority = 2, enabled = true)
public void classB_Method1(/*String... excelData*/) throws Exception {

}

/////////////////////////////////////////////////////////////////////////////
// ****SetUp and Tear Down

@BeforeTest(alwaysRun=true)
public void setupClass() throws Exception {
}


@BeforeMethod(alwaysRun=true)
public void setupMethod(Method method) throws Exception {
    SeleniumHelperDebug.setCurrentMethodName(method.getName());
    SeleniumHelperDebug.defaultBeforeMethod(); 

}

}

辅助方法

public class SeleniumHelperDebug { 



    //Name of the method/Test being run
    private static String currentMethodName;
    public static String getCurrentMethodName() {
        return currentMethodName;
    }
    public static void setCurrentMethodName(String currentMethodName) {
        System.out.println("!! Setting Method name to: "+ currentMethodName);
        SeleniumHelperDebug.currentMethodName = currentMethodName;
    }

    //Setup Method. BeforeTest
    public static void defaultBeforeMethod() throws Exception {
        Thread.sleep(500);
        /*setCurrentMethodName(method.getName());*/
        System.out.println("INFO: Name of Test from Before Method: " +getCurrentMethodName() );


        System.out.println("REMINDER: Keep Browser Window in Foreground to Help prevent F@ilures");
    }
}

您的Seleniumhelperdebug类是静态的，因此不是安全的。有什么原因为什么您不能每个测试实例？

您试图用Seleniumhelperdebug类解决什么问题？

可能有一个更好的解决方案，即线程安全，但尚不清楚该类试图实现什么
