public class AndroidAddContactsTest {
    private AppiumDriver driver;

  @BeforeMethod

  }

  @AfterMethod
  public void afterMethod() throws Exception {
      driver.quit();
  }

  @Test

代码在 JUnit 下运行正确，移植到 TestNG 下就报错了

是不是 xml 的问题，你把你 run 的那个 xml 贴出来看看

杨秋强 #4 · 2014年09月05日 Author

#3 楼 @cy_suncheng 创建工程时没有 xml

rhyme #5 · 2014年09月05日

#4 楼 @sas 你用的不是 TestNG 么？没有 xml 那你怎么 run 的？

杨雅洁 #6 · 2014年09月11日

org.testng.TestNGException: java.lang.NullPointerException 没有设置 xml 模板，工程右键属性，testNG， template 值需要设置一下。
