testNG XML文件不考虑我的第二个类只运行我的第一个类，第二个类显示java.lang.NullPointerException

标签： java selenium-webdriver testng

当我运行XML时，第一个类正在运行。第一类包含@beforeTest和@AfterTest注释。我的@Test注释是在第二类，但它没有运行。 

<suite name = "smsweb">

试试这个，它应该有效。 

<suite name = "smsweb"> 
    <test name = "login">
        <classes>
            <class name = "testNG.datapro" /> 
        </classes>
        <classes>           
            <class name = "testNG.assetscat" /> 
        </classes>
    </test> 
</suite>

答案 1 :(得分：0)

TestNG保证@BeforeTest带注释的方法每<test>个标签只执行一次。您还没有向我们展示您的测试代码。但是按照你的描述，我猜你的两个测试类都有@Test个方法，这些方法依赖于一个预期通过@BeforeTest方法初始化的变量，这个@BeforeTest方法可能也许一些共同基类的一部分。

如果您的用例绝对需要每<test>只进行一次初始化，那么您可能需要执行以下操作：

将初始化逻辑移动为

的一部分
  • org.testng.ITestListener - 如果您希望每个测试标记只执行一次设置（即，而不是使用@BeforeTest）
  • org.testng.ISuiteListener - 如果您希望每个套件标签只执行一次设置（即，而不是使用@BeforeSuite）
  • 使用setAttribute（）方法将初始化数据持久化为ITestContext（这代表测试标记）或ISuite（这代表套件标记）的属性。
  • 通过以下方式将此监听器连接到TestNG：
    • 侦听器标记（或）
    • @Listeners注释（或）
    • 服务加载器。

您可以参考我的this博客文章以获取更多详细信息以及一些显示所有这些内容的示例。

查看来源代码后的更新

你完全弄错了。实例化类和TestNG实例化类之间存在差异。访问webdriver数据成员时assetscat.entername()失败并NullPointerException的原因是因为所有初始化都在webopen()中完成，并使用@BeforeTest注释。

要解决此问题，您有两种选择：

  1. 在尝试访问其中的webopen()对象之前，在assetscat.entername()方法中显式调用方法driver。
  2. 拥有assetscat extends datapro。

    3. 我还建议你花一些时间处理所有这些注释，以便更好地理解如何使用它们。

答案 2 :(得分：0)

尝试此代码，这将使两个测试都运行

<suite name = "smsweb"> 
    <test name = "login">
        <classes>

            <class name = "testNG.datapro" />  

            <class name = "testNG.assetscat" />
        </classes>
    </test> 
</suite>
