该脚本有methods = parallel . 但它在任何给定时间内只执行一种方法，并为另一种方法提供错误 .

testng脚本：

<suite name="test suite" verbose="1" parallel="methods" thread-count="3">

<test name="test on FF">
<parameter name="platform" value="local" />
<parameter name="browser" value="firefox" />
<parameter name="version" value="13" />
<parameter name="login" value="test" />
<classes>
  <class name="com.auto.tests.TitlesTests" >
    <methods>
        <include name="testCreateNewTitle" />
        <exclude name="testCreateNewTitlesFolder" />
        <include name="testCreateNewTitlesUsingAuto" />
    </methods>
  </class>
  </classes>

BeforeClass，BeforeMethod，BeforeSuite在一个脚本中，@ Test selenium webdriver测试在另一个脚本中 .

Class A

@BeforeSuite
public void beforeSuite() throws Exception {
    log.info("BeforeSuite");
}

    @BeforeTest
public void beforeTest() throws Exception{

        setupBrowser("Default test");
    }
}

    @BeforeClass
public void beforeClass() throws Exception {
    if(loginMethod.equalsIgnoreCase("class")){
        setupBrowser(this.getClass().getSimpleName());
    }
}

    @BeforeMethod
public void beforeMethod(Method method) throws Exception {
    log.info("BeforeMethod");
    if(loginMethod.equalsIgnoreCase("method")){
        setupBrowser(method.getName());
    }
}

class B extends A {

 @Test
public void testCreateNewtitle(){
                log.info("Create new title test case1 starts");
        log.info("Create folder1 worked");
        }

@Test
public void testCreateNewTitlesUsingAuto(){
                log.info("Create new title test case2 starts");
        log.info("Create folder2 worked");
        }

}
