代码执行testng的几种方式

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<String,String> 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<XmlClass> classes = new ArrayList<>();
        String packageName = TestngRun.class.getPackage().getName();
        classes.add(new XmlClass(packageName+".FirstTest"));
        xmlTest.setXmlClasses(classes);
        List<XmlSuite> 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

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="All Test Suite">
    <test verbose="2" preserve-order="true" name="test">
        <classes>
            <class name="cas.eric.FirstTest"></class>
        </classes>
    </test>
</suite>

TestngRun.java

 package cas.eric;

 import org.apache.commons.io.FileUtils;
 import org.testng.TestNG;
 import java.io.File;
 import java.io.IOException;
 import java.io.InputStream;
 import java.util.ArrayList;
 import java.util.List;

 public class TestngRun {

     public static void main(String[] args) {
         try {
             String xmlName = "testng.xml";
             //读取文件到流
             InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);
             //新建一个文件对象
             File xmlFile = new File("name.xml");
             //拷贝流的内容到新文件中
             FileUtils.copyInputStreamToFile(inputStream,xmlFile);
             TestNG testNG = new TestNG();
             List<String> suites = new ArrayList<>();
             //添加文件到suite
             suites.add(xmlFile.getAbsolutePath());
             testNG.setTestSuites(suites);
             testNG.run();
         }
         catch (IOException e) {
             e.printStackTrace();
         }
     }

 }

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

 package cas.eric;

 import org.testng.TestNG;
 import org.testng.xml.SuiteXmlParser;
 import org.testng.xml.XmlSuite;
 import java.io.InputStream;
 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) {
         String xmlName = "testng.xml";
         InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);
         TestNG testNG = new TestNG();
         SuiteXmlParser suiteXmlParser = new SuiteXmlParser();
         List<XmlSuite> suites = new ArrayList<>();
         XmlSuite xmlSuite = suiteXmlParser.parse(xmlName, inputStream, true);
         suites.add(xmlSuite);
         Map<String,String> parameters = new HashMap<>();
         parameters.put("name", "wangwu");
         xmlSuite.setParameters(parameters);
         testNG.setXmlSuites(suites);
         testNG.run();

     }

 }

执行结果：

test one
wangwu

当然也可以自定义test class

SecondTest.java

 package cas.eric;

 import org.testng.annotations.Optional;
 import org.testng.annotations.Parameters;
 import org.testng.annotations.Test;

 public class SecondTest {

     @Test
     @Parameters({"name"})
     public void test_two(@Optional("mike") String name){
         System.out.println("test two");
         //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);
     }
 }

TestngRun.java

 package cas.eric;

 import org.testng.TestNG;
 import org.testng.xml.SuiteXmlParser;
 import org.testng.xml.XmlClass;
 import org.testng.xml.XmlSuite;
 import org.testng.xml.XmlTest;

 import java.io.InputStream;
 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) {
         String xmlName = "testng.xml";
         InputStream inputStream = TestngRun.class.getClassLoader().getResourceAsStream(xmlName);
         TestNG testNG = new TestNG();
         SuiteXmlParser suiteXmlParser = new SuiteXmlParser();
         List<XmlSuite> suites = new ArrayList<>();
         XmlSuite xmlSuite = suiteXmlParser.parse(xmlName, inputStream, true);
         List<XmlTest> xmlTestList = xmlSuite.getTests();
         XmlTest xmlTest = xmlTestList.get(0);
         List<XmlClass> xmlClassList = xmlTest.getXmlClasses();
         String packageName = TestngRun.class.getPackage().getName();
         XmlClass xmlClass = new XmlClass(packageName+".SecondTest");
         xmlClassList.add(xmlClass);
         suites.add(xmlSuite);
         Map<String,String> parameters = new HashMap<>();
         parameters.put("name", "wangwu");
         xmlSuite.setParameters(parameters);
         testNG.setXmlSuites(suites);
         testNG.run();

     }

 }

运行结果：

test one
wangwu
test two
wangwu
