testNG XML文件不考慮我的第二類它的運行只有我的第一個類，第二個它的顯示java.lang.NullPointerException

Question

當我運行我的XML第一類正在運行。第一類包含@beforeTest和@AfterTest註釋。我的@Test註釋是在第二課，但它沒有運行。

<suite name = "smsweb"> 
    <test name = "login"> 
     <classes> 
      <class name = "testNG.datapro" /> //Running 
     </classes> 
    </test> 
    <test name = "form"> 
     <classes>   
      <class name = "testNG.assetscat" /> //not running 
     </classes> 
    </test>

Answer 1

TestNG的保證，一個@BeforeTest批註的方法得到每<test>標籤只執行一次。您沒有向我們展示您的測試代碼。但是，根據你的描述，我猜測你的兩個測試類都有@Test方法，這些方法依賴於一個變量，這個變量預計會通過@BeforeTest方法初始化，而這個@BeforeTest方法也許是一些通用基類的一部分。

如果你使用的情況下絕對需要初始化做每<test>只有一次，那麼你可能要做到以下幾點：

移動初始化邏輯，要麼

• org.testng的一部分。 ITestListener - 如果您希望每個測試標籤僅執行一次設置（即，而不是使用@BeforeTest）
• org.testng.ISuiteListener - 如果您希望每個套件標籤只執行一次設置（即，而不是使用@BeforeSuite）
• 使用setAttribute（）方法將初始化數據作爲ITestContext（表示測試標記）或ISuite（表示套件標記）的屬性來持久化。
• 電線在此偵聽到TestNG的通過：
  • 聽者標籤（或）
  • 的@Listeners註解（或）
  • 服務裝載機。

你可以參考我的this博客文章，以獲得更多的細節，也爲一些樣品，顯示了這一切。

更新後綜觀源代碼

你已經完全得到了這個錯誤。實例化一個類和TestNG實例化一個類是有區別的。訪問網絡驅動器數據成員時，您的assetscat.entername()失敗，原因是NullPointerException是因爲所有初始化都在webopen()中完成，並且使用@BeforeTest註釋。

爲了解決這個問題，你有兩種選擇：

1. 試圖訪問它的driver對象之前顯式調用該方法webopen()在assetscat.entername()方法。
2. 有assetscat extends datapro。

我還建議您花些時間處理所有這些註釋，以更好地瞭解如何使用它們。

Answer 2

試試這個，它應該工作。

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

Answer 3

試試這個代碼，這將使這兩個測試運行

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

      <class name = "testNG.datapro" /> 

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