如何在TestNG中使用Beanshell脚本?
TestNG支持基于相似功能或用途对测试用例进行分组。
有时,用户需要根据条件和用例在运行时自定义选择类/方法/组。TestNG支持简单的常用场景,但涵盖所有预期是不必要的。例如,用户可以向单个测试添加多个组。使用`
但是,如果用户只想在提及所有组(即AND语句)时运行测试。TestNG不直接支持组中的AND语句。例如:@Test ( groups = {“unit”, “integration”} )
如果用户只想在组被同时指定为“unit”和“integration”(而不是“unit”或“integration”)时运行此测试。
此功能可以通过Beanshell实现。它为用户提供了脚本功能,以便根据需要在testng.xml中设置自定义条件。用户可以添加任何条件作为脚本,以获取所需的测试/方法/类/组或任何其他内容。
在本教程中,我们将说明如何在testng.xml中实现Beanshell以实现自定义条件。示例针对多个组条件。
解决此问题的方法/算法
步骤1:创建TestNG类 - NewTestngClass
步骤2:在所有类中编写3个@Test方法,其中两个为单一组,一个具有两个组。
步骤3:现在创建如下所示包含Beanshell脚本的testng.xml。
步骤4:如果您单独运行testng.xml(不是使用maven),请确保已下载并正确配置Beanshell jar。
步骤5:如果您正在运行作为maven构建一部分的testng.xml,请在pom.xml中添加beanshell依赖项。
步骤6:现在,直接运行testng.xml或使用mvn命令。
示例
以下代码展示如何仅基于自定义条件运行测试组
src/ NewTestngClass.java
import org.testng.annotations.Test; public class NewTestngClass { @Test(groups = { "unit", "integration" }) public void testCase1() { System.out.println("in test case 1 of NewTestngClass"); } @Test(groups = { "integration" }) public void testCase2() { System.out.println("in test case 2 of NewTestngClass"); } @Test(groups = { "unit" }) public void testCase3() { System.out.println("in test case 3 of NewTestngClass"); } }
testng.xml
这是一个用于组织和运行TestNG测试用例的配置文件。
当只需要执行有限的测试而不是完整的套件时,它非常方便。
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd"> <suite name="suite" parallel="none" verbose="5"> <test name="test"> <method-selectors> <method-selector> <script language="beanshell"><![CDATA[ return groups.containsKey("unit") && groups.containsKey("integration"); ]]></script> </method-selector> </method-selectors> <classes> <class name="NewTestngClass"/> </classes> </test> </suite>
pom.xml
这是一个maven配置文件,用于组织依赖项、插件和运行TestNG测试用例。
当只需要执行有限的测试而不是完整的套件时,它非常方便。
