硒網格，測試開始在同一線程並行運行時開始

Question

使用selenium網格與TestNg運行並行測試，@BeforeTest方法似乎在同一個線程上啓動兩個測試，任何想法爲什麼？我試圖確保每個測試類都從它自己的線程開始。

@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"); 
} 

然而，這裏是對數圖中，兩個試驗班開始在同一個線程，並獲得創建只有兩個驅動程序，這會引發各種與聽衆和報告頭痛。

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 

這裏顯示三個測試類的ANT XML文件...

<?xml version="1.0"?>

在哪一個類你定義beforeTest方法。 我創建了相同的結構，下面的代碼在不同的線程上爲我工作。

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"); 
    } 
} 

我已經使用了相同的testng xml配置文件，下面是我的輸出。
