导入testng管理测试用例

1.在pom.xml中增加testng的依赖，以导入testNG

2.在src-main-resources目录下新建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的区别

 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>

执行结果：

将BeforeTest替换为BeforeClass，AfterTest替换为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>

执行结果：

4.使用TestNg增加断言

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");}
}

将expectMessage修改为abc，结果为

 5.编写基于TestNg的测试用例

Baidu.java

package testcase;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.annotations.AfterTest;
import org.testng.annotations.BeforeTest;
import org.testng.annotations.Test;

import java.util.concurrent.TimeUnit;
public class Baidu {
    private WebDriver driver;
    @BeforeTest
    public void setUp(){
        String chromepath = System.getProperty("user.dir")+"/src/main/java/drivers/chromedriver";
        System.setProperty("webdriver.chrome.driver",chromepath);
        driver = new ChromeDriver();
        driver.manage().timeouts().implicitlyWait(30,TimeUnit.SECONDS);
    }
    @Test
    public void test(){
        driver.get("https://www.baidu.com");
        driver.findElement(By.xpath("//input[@class='s_ipt' and @id='kw']")).sendKeys("selenium");
        driver.findElement(By.xpath("//input[@id='su']")).click();
        System.out.println(driver.findElement(By.xpath("//span[@class='nums_text']")).getText());

    }
    @AfterTest
    public void tearDown(){
        driver.quit();
    }
}

test.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.Baidu" />
        </classes>

    </test>
</suite>

测试结果：
