TestNG從父類繼承@Parameters

Question

我試圖去使用TestNG爲併發跨瀏覽器測試框架工作一個存根。但似乎我無法擺脫父類@參數並不斷得到

Parameter 'browsername' is required by @Configuration on method setup but has not been marked @Optional or defined

的testng.xml

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> 
<suite name="1265_Suite" parallel="tests" verbose="2" thread-count="2" preserve-order="true"> 
    <test name="92" parallel="false" preserve-order="true"> 
     <classes> 
      <class name="com.javacodegeeks.testng.maven.BaseTest"/> 
      <class name="com.javacodegeeks.testng.maven.ChildTest"/> 
      <parameter name="browsername" value="chrome"/> 
     </classes> 
    </test> 
    <test name="93" parallel="false" preserve-order="true"> 
     <classes> 
      <class name="com.javacodegeeks.testng.maven.BaseTest"/> 
      <class name="com.javacodegeeks.testng.maven.ChildTest"/> 
      <parameter name="browsername" value="firefox"/> 
     </classes> 
    </test> 
</suite> 

BaseTest

public class BaseTest extends Assert { 

    protected String browser; 

    @BeforeClass 
    @Parameters({"browsername"}) 
    public void setup(String browsername) { 
     System.err.println("Browser name in @BeforeClass is " + browsername); 
     this.browser = browsername; 
    } 
} 

ChildTest

public class ChildTest extends BaseTest { 

    @Test 
    public void test() { 
     System.out.println(browser); 
    } 
} 

我沒有找到足夠的信息關於如何使這個工作，所以如果你有任何想法，我想聽聽他們。

已經檢查，但沒有足夠的信息： TestNG Annotations in a Superclass

與<parameter>節點再次嘗試<test>節點上（和BaseTest應該是無用的）：

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd"> 
<suite name="1265_Suite" parallel="tests" verbose="2" thread-count="2" preserve-order="true"> 
    <test name="92" parallel="false" preserve-order="true"> 
     <parameter name="browsername" value="chrome"/> 
     <classes> 
      <!--class name="com.javacodegeeks.testng.maven.BaseTest"/--> 
      <class name="com.javacodegeeks.testng.maven.ChildTest"/> 
     </classes> 
    </test> 
    <test name="93" parallel="false" preserve-order="true"> 
     <parameter name="browsername" value="firefox"/> 
     <classes> 
      <!--class name="com.javacodegeeks.testng.maven.BaseTest"/--> 
      <class name="com.javacodegeeks.testng.maven.ChildTest"/> 
     </classes> 
    </test> 
</suite>
