一、指定test class

Test class FirstTest

package cas.eric;import org.testng.annotations.Optional;import org.testng.annotations.Parameters;import org.testng.annotations.Test;public class FirstTest {    @Test    @Parameters({
    "name"})    public void test_one(@Optional("zhangsan") String name){        System.out.println("test one");        //如果变量name有值则打印传入的name值，如果没有则打印默认值zhangsan        System.out.println(name);    }}

 

 

执行testng的class：TestngRun

package cas.eric;import org.testng.TestNG;import org.testng.xml.XmlClass;import org.testng.xml.XmlSuite;import org.testng.xml.XmlTest;import java.util.ArrayList;import java.util.HashMap;import java.util.List;import java.util.Map;public class TestngRun {    public static void main(String[] args) {        //新建一个XmlSuite对象        XmlSuite xmlSuite = new XmlSuite();        //指定xmlsuite 名称        xmlSuite.setName("xml test suite");        //指定name 参数值        Map
     
       parameters = new HashMap<>();        parameters.put("name", "lisi");        //xmlsuite添加parameters        xmlSuite.setParameters(parameters);        //新建一个XmlTest对象        XmlTest xmlTest = new XmlTest(xmlSuite);        //设置xmltest 名称        xmlTest.setName("xml test");        //新建xmlclass 对象        List
      
        classes = new ArrayList<>();        String packageName = TestngRun.class.getPackage().getName();        classes.add(new XmlClass(packageName+".FirstTest"));        xmlTest.setXmlClasses(classes);        List
       
         suites = new ArrayList<>();        suites.add(xmlSuite);        TestNG testNG = new TestNG();        testNG.setXmlSuites(suites);        testNG.run();    }}
       
      
     

 

打印结果：

test one

lisi

二、指定xml文件

testng.xml

 

TestngRun.java

1 package cas.eric; 2  3  4 import org.apache.commons.io.FileUtils; 5 import org.testng.TestNG; 6 import java.io.File; 7 import java.io.IOException; 8 import java.io.InputStream; 9 import java.util.ArrayList;10 import java.util.List;11 12 public class TestngRun {13 14     public static void main(String[] args) {15         try {16             String xmlName = "testng.xml";17             //读取文件到流18             InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);19             //新建一个文件对象20             File xmlFile = new File("name.xml");21             //拷贝流的内容到新文件中22             FileUtils.copyInputStreamToFile(inputStream,xmlFile);23             TestNG testNG = new TestNG();24             List
     
       suites = new ArrayList<>();25             //添加文件到suite26             suites.add(xmlFile.getAbsolutePath());27             testNG.setTestSuites(suites);28             testNG.run();29         }30         catch (IOException e) {31             e.printStackTrace();32         }33     }34 35 }
     

 

执行结果：

test one

zhangsan

打印了默认的name：zhangsan，那使用xml方式执行的时候如何传入参数呢

 

三、执行xml文件以及自定义传参

TestngRun.java

 

1 package cas.eric; 2  3  4  5 import org.testng.TestNG; 6 import org.testng.xml.SuiteXmlParser; 7 import org.testng.xml.XmlSuite; 8 import java.io.InputStream; 9 import java.util.ArrayList;10 import java.util.HashMap;11 import java.util.List;12 import java.util.Map;13 14 public class TestngRun {15 16     public static void main(String[] args) {17         String xmlName = "testng.xml";18         InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);19         TestNG testNG = new TestNG();20         SuiteXmlParser suiteXmlParser = new SuiteXmlParser();21         List
     
       suites = new ArrayList<>();22         XmlSuite xmlSuite = suiteXmlParser.parse(xmlName, inputStream, true);23         suites.add(xmlSuite);24         Map
      
        parameters = new HashMap<>();25         parameters.put("name", "wangwu");26         xmlSuite.setParameters(parameters);27         testNG.setXmlSuites(suites);28         testNG.run();29         30     }31 32 }
      
     

 

执行结果：

test one

wangwu

 

当然也可以自定义test class

SecondTest.java

1 package cas.eric; 2  3  4 import org.testng.annotations.Optional; 5 import org.testng.annotations.Parameters; 6 import org.testng.annotations.Test; 7  8 public class SecondTest { 9 10     @Test11     @Parameters({"name"})12     public void test_two(@Optional("mike") String name){13         System.out.println("test two");14         //如果变量name有值则打印传入的name值，如果没有则打印默认值zhangsan15         System.out.println(name);16     }17 }

 

TestngRun.java

1 package cas.eric; 2  3  4  5 import org.testng.TestNG; 6 import org.testng.xml.SuiteXmlParser; 7 import org.testng.xml.XmlClass; 8 import org.testng.xml.XmlSuite; 9 import org.testng.xml.XmlTest;10 11 import java.io.InputStream;12 import java.util.ArrayList;13 import java.util.HashMap;14 import java.util.List;15 import java.util.Map;16 17 public class TestngRun {18 19     public static void main(String[] args) {20         String xmlName = "testng.xml";21         InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);22         TestNG testNG = new TestNG();23         SuiteXmlParser suiteXmlParser = new SuiteXmlParser();24         List
     
       suites = new ArrayList<>();25         XmlSuite xmlSuite = suiteXmlParser.parse(xmlName, inputStream, true);26         List
      
        xmlTestList = xmlSuite.getTests();27         XmlTest xmlTest = xmlTestList.get(0);28         List
       
         xmlClassList = xmlTest.getXmlClasses();29         String packageName = TestngRun.class.getPackage().getName();30         XmlClass xmlClass = new XmlClass(packageName+".SecondTest");31         xmlClassList.add(xmlClass);32         suites.add(xmlSuite);33         Map
        
          parameters = new HashMap<>();34         parameters.put("name", "wangwu");35         xmlSuite.setParameters(parameters);36         testNG.setXmlSuites(suites);37         testNG.run();38 39     }40 41 }
        
       
      
     

 

运行结果：

test one

wangwu

test two

wangwu
