Selenium 网格，测试在并行运行时从同一个线程开始答案

【问题标题】：Selenium grid, tests start starting on the same thread when run in parallelSelenium 网格，测试在并行运行时从同一个线程开始

【问题描述】：

使用 Selenium 网格和 TestNg 运行并行测试，@BeforeTest 方法似乎在同一个线程上启动两个测试，有什么想法吗？我试图确保每个测试类都在自己的线程上开始。

@BeforeTest(alwaysRun = true)
@Parameters({ "selenium.OS", "selenium.browser","selenium.testClassNameHere" })
public void beforeTest(String OS, String browser, String testClassNameHere) {
    Out.trace("Starting beforeTest for "+testClassNameHere+" on thread:  " + Thread.currentThread().hashCode());
    //create driver here
    Out.trace("beforeTest has finished");
}

但是，这里有日志，显示两个测试类在同一个线程上启动，并且只创建了两个驱动程序，这给监听器和报告带来了各种各样的麻烦。

TRACE: Starting beforeTest for AcceptanceTests.ErrorReportingTests on thread:  777376239
TRACE: Starting beforeTest for AcceptanceTests.PopupTests on thread:  777376239
TRACE: Starting beforeTest for AcceptanceTests.LoginPageTests on thread:  1235740568
TRACE: Finished making driver.
TRACE: Finished making driver.
TRACE: beforeTest has finished
TRACE: beforeTest has finished

这是显示三个测试类的 ANT xml 文件...

<?xml version="1.0"?>
<suite name="Debugging QA Tests" parallel="tests" thread-count="10">
   <test name="Popup Tests" preserve-order="true" >
        <parameter name="selenium.OS" value="localhost" />

        <parameter name="selenium.testClassNameHere" value="AcceptanceTests.PopupTests" />

         <classes>
            <class name="qaautomation.AcceptanceTests.ErrorReportingTests" />
        </classes>
    </test>
</suite>

【解决方案1】：

您在哪个类中定义了beforeTest 方法。我创建了相同的结构，以下代码在不同的线程上为我工作。

public class TestCase {

    @BeforeTest(alwaysRun = true)
    @Parameters({ "selenium.OS", "selenium.browser","selenium.testClassNameHere" })
    public void beforeTest(String OS, String browser, String testClassNameHere) {
        System.out.println("Starting beforeTest for "+testClassNameHere+" on thread:  " + Thread.currentThread().hashCode());
        //create driver here
        System.out.println("beforeTest has finished");
    }
}

public class PopupTests extends TestCase{

    @Test(description="popup reporting")
    public void teszt()
    {
        System.out.println("popup");
    }
}
public class ErrorReportingTests extends TestCase{

    @Test(description="error reporting")
    public void teszt()
    {
        System.out.println("Error");
    }
}

public class LoginPageTests extends TestCase {

    @Test(description="login reporting")
    public void teszt()
    {
        System.out.println("Login");
    }
}

并且我使用了与您给出的相同的 testng xml 配置文件，以下是我的输出。

Starting beforeTest for AcceptanceTests.ErrorReportingTests on thread:  1968879864
beforeTest has finished
Starting beforeTest for AcceptanceTests.LoginPageTests on thread:  88161428
beforeTest has finished
Starting beforeTest for AcceptanceTests.PopupTests on thread:  1040963230
