1.在pom.xml中增加testng的依賴，以導入testNG

2.在src-main-resources目錄下新建xml文件，比如untitled.xml.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="testSuite1">
      <test name="UITest">
          <classes>
              <class name="testcase.TestNG" />
              <class name="testcase.testNG2" />
              <class name="testcase.testNG1" />
          </classes>

      </test>
</suite>

3.BeforeTest AfterTest BeforeClass AfterClass的區別

BeforeTest AfterTest

case1:

package testcase;

import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class testNG3 {
    @BeforeTest
    public void setup(){System.out.println("case3:set up");}
    @Test
    public void test1(){System.out.println("case3");}
    @AfterTest
    public void tearup(){System.out.println("case3:tear down");}
}

case2:

package testcase;

import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

public class testNG4 {
    @BeforeTest
    public void setup(){System.out.println("case4:set up");}
    @Test
    public void test1(){System.out.println("case4");}
    @AfterTest
    public void tearup(){System.out.println("case4:tear down");}
}

xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="testSuite1">
      <test name="UITest">
          <classes>
              <!--<class name="testcase.TestNG" />
              <class name="testcase.testNG2" />
              <class name="testcase.testNG1" />-->
              <class name="testcase.testNG3"/>
              <class name="testcase.testNG4"/>
          </classes>

      </test>
</suite>
執行結果：

將BeforeTest替換為BeforeClass，AfterTest替換為AfterClass

case1:

package testcase;

import org.testng.annotations.*;

public class testNG3 {
    @BeforeClass
    public void setup(){System.out.println("case3:set up");}
    @Test
    public void test1(){System.out.println("case3");}
    @AfterClass
    public void tearup(){System.out.println("case3:tear down");}
}

case2:

package testcase;

import org.testng.annotations.*;

public class testNG4 {
    @BeforeClass
    public void setup(){System.out.println("case4:set up");}
    @Test
    public void test1(){System.out.println("case4");}
    @AfterClass
    public void tearup(){System.out.println("case4:tear down");}
}

xml:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="testSuite1">
      <test name="UITest">
          <classes>
              <!--<class name="testcase.TestNG" />
              <class name="testcase.testNG2" />
              <class name="testcase.testNG1" />-->
              <class name="testcase.testNG3"/>
              <class name="testcase.testNG4"/>
          </classes>

      </test>
</suite>

執行結果：

4.使用TestNg增加斷言

package testcase;
import org.testng.Assert;
import org.testng.annotations.*;
public class testNG3 {
    @BeforeClass
    public void setup(){System.out.println("case3:set up");}
    @Test
    public void test1(){
        System.out.println("case3");
        String actureMessage="abc";
        String expectMessage="efg";
        Assert.assertTrue(actureMessage.equalsIgnoreCase(expectMessage),"Expect message is "+expectMessage+".But acture message is "+actureMessage);
    }
    @AfterClass
    public void tearup(){System.out.println("case3:tear down");}
}

將expectMessage修改為abc，結果為

導入testng管理測試用例
