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
