TestNG--入门

安装TestGN

安装流程

在eclispe中安装TestNG Link
Eclipse > Help > install new software > Enter "http://beust.com/eclipse/" in the Work with box > add TestNG > waiting loading > select TestNG > install > next > next > i accept > Finish

after loading done> install anyway > restart

2.也可以使用链接中的方法三，下载文件解压到eclipse安装包dropins路径下的新文件夹中

eclipse\dropins\testng-eclipse-6.11\

安装成功的显示

创建TestNG project在eclipse

打开eclipse > File > new Project

step1
输入 name 然后 click next , 请不要选择 finish

step2
当点击next之后，在libraries一栏去添加jar包，由于已经将TestNG都添加到eclipse中，所以不选咋导入额外jar包而是选择 Add Libraries

step3
导入Selenuim的jar包
导入selenium的jar包
先去下载jar包并解压到相关的文件中，下载路径为http://docs.seleniumhq.org/download/
我自己在project下面创建了一个lib文件，然后将jar包复制到该路径下

将其导入

创建一个新的testNG test file

自己设置packageName和class name

然后就会生成如下的class

下载与浏览器相关版本的driver， Chrome的网站为https://chromedriver.chromium.org/downloads；注意一定要检查自己浏览器对应的版本

输入代码然后run as TestNG

package demoPakage;

import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.*;

public class NewTestng {
    public String baseUrl = "http://demo.guru99.com/test/newtours/";
    String driverPath = "D:\\EclipseSpace\\firstTestNGProject\\data\\chromedriver.exe";
    public WebDriver driver ; 
     
  @Test
  public void verifyHomepageTitle() {
      System.out.println("launching firefox browser"); 
      System.setProperty("webdriver.chrome.marionette", driverPath);
      driver = new ChromeDriver();
      driver.get(baseUrl);
      String expectedTitle = "Welcome: Mercury Tours";
      String actualTitle = driver.getTitle();
      Assert.assertEquals(actualTitle, expectedTitle);
//      driver.close();
  }
}

查看html report

参数化的使用
代码如下

package demoPakage;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.*;
public class demo2 {
     public String baseUrl = "http://demo.guru99.com/test/newtours/";
        String driverPath = "D:\\\\EclipseSpace\\\\firstTestNGProject\\\\data\\\\chromedriver.exe";
        public WebDriver driver ; 
         @AfterTest                            //Jumbled
          public void terminateBrowser(){
              driver.close();
          }
         @BeforeTest                            //Jumbled
          public void launchBrowser() {
              System.out.println("launching chrome browser"); 
              System.setProperty("webdriver.chrome.marionette", driverPath);
              driver = new ChromeDriver();
              driver.get(baseUrl);
          }
          @Test(priority = 0)                                //Jumbled
          public void verifyHomepageTitle2() {
              String expectedTitle = "Welcome: Mercury Tours";
              String actualTitle = driver.getTitle();
              Assert.assertEquals(actualTitle, expectedTitle);
         }
          
          @Test (priority = 1)
          public void verifySecurityProject() {
              String expectedTitle = "Security Project";
              String actualTitle = driver.findElement(By.xpath("//*[@id=\"navbar-brand-centered\"]/ul/li[6]/a")).getText();
              Assert.assertEquals(actualTitle, expectedTitle);
         }
}

priority的数字越小优先级越高

使用参数化xml文件来运行testng中的case

TestNG教程：简单实例

TestNG是一个自动化的测试框架，其中NG的意思是“Next Generation”；它是收到Junit的启发来创建的。使用TestNG，你可以产生一个适宜的report，而且容易知道那些case已经pass；那些是skip的。
你还可以单独去执行failed的case，TestNG提供来一个选项，在输出文件夹中有一个Testng-failed.xml文件，如果你希望执行失败的case，那你就可以直接去运行这个文件。
除了这些简单的概念你能理解，你也可以学习进阶篇，如何使用@test标签来创建一个测试方法；如何将这些class转换成测试集文件，然后使用命令行和eclipse来运行。

创建一个新的TestNG Class： demo2
代码如下
这个代码是熟悉常用的groups属性，将所有的methods添加上相应的group信息，注意其中的beforeGroup和afterGroup也有相应的参数（groups = { }）

如果代码没有指定任何的运行设置属性，那么会按照字母进行排序运行

package demoPakage;
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.*;
import org.testng.internal.GroupsHelper;
public class demo2 {
     public String baseUrl = "http://demo.guru99.com/test/newtours/";
        String driverPath = "D:\\\\EclipseSpace\\\\firstTestNGProject\\\\data\\\\chromedriver.exe";
        public WebDriver driver ; 
        

        
          @AfterGroups (groups = {"test1", "test2"})
//        @Test (groups = {"test2","test1"})
          
          public void terminateBrowser(){
            System.out.println("closed it");
              driver.close();
          }
        
          @BeforeGroups (groups = {"test1", "test2"})
//        @Test (groups = {"test2","test1"})
          
          public void launchBrowser() {
              System.out.println("launching chrome browser"); 
              System.setProperty("webdriver.chrome.marionette", driverPath);
              driver = new ChromeDriver();
              driver.get(baseUrl);
          }
         
         
          @Test (groups = {"test1"})
          public void verifyHomepageTitle2() {
              System.out.println("testing1");
             String expected = "Welcome: Mercury Tours";
             String actualString = driver.getTitle();
             Assert.assertEquals(actualString, expected);
         }
          
          
          @Test (groups = {"test2"})
          public void check2() {
              System.out.println("check2 gogogo");
              String expected = "Sign-on: Mercury Tours";
              driver.findElement(By.partialLinkText("SIGN-ON")).click();
              String actualString = driver.getTitle();
              Assert.assertEquals(actualString, expected);
              
          }

          
}

然后

生成一个testng.xml文件然后添加具体的class 和 group信息

点击RunAs > Run config > 选择具体的project 和suit文件点击run

testng.xml文件中设置的dependon

xml文件的层级结果

TestNG Listeners in Selenium

有两种主要的Listener： WebDriver Listener 和 TestNG Listener；主要使用testng lisenter
listeners就是用来调整默认的TestNG行为的接口，可以用来自定义report和log。 TestNG本身包含很多listener

IAnnotationTransformer ,
IAnnotationTransformer2 ,
IConfigurable ,
IConfigurationListener ,
IExecutionListener,
IHookable ,
IInvokedMethodListener ,
IInvokedMethodListener2 ,
IMethodInterceptor ,
IReporter,
ISuiteListener,
ITestListener .

ItestListener 为例，它主要包含下面几个方法

OnStart- OnStart method is called when any Test starts.
onTestSuccess- onTestSuccess method is called on the success of any Test.
onTestFailure- onTestFailure method is called on the failure of any Test.
onTestSkipped- onTestSkipped method is called on skipped of any Test.
onTestFailedButWithinSuccessPercentage- method is called each time Test fails but is within success percentage.
onFinish- onFinish method is called after all Tests are executed.

Step by Step for ITestlistener

创建一个class 继承“ITestListener”
source > override/implement methods >

selectAll and click OK

于是得到如下：

重写其中的部分代码

package demoPakage;

import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;

public class listenerDemo implements ITestListener {

    @Override
    public void onTestStart(ITestResult result) {
        // TODO Auto-generated method stub
        System.out.println("* START * :"+result.getName());
    }

    @Override
    public void onTestSuccess(ITestResult result) {
        // TODO Auto-generated method stub
        System.out.println("*** passed :"+result.getName() );
    }

    @Override
    public void onTestFailure(ITestResult result) {
        // TODO Auto-generated method stub
        System.out.println("---- failed :" +result.getName());
    }

    @Override
    public void onTestSkipped(ITestResult result) {

        // TODO Auto-generated method stub
        System.out.println("    skiped :"+result.getName());
    }

    @Override
    public void onTestFailedButWithinSuccessPercentage(ITestResult result) {
        // TODO Auto-generated method stub
        ITestListener.super.onTestFailedButWithinSuccessPercentage(result);
    }

    @Override
    public void onTestFailedWithTimeout(ITestResult result) {
        // TODO Auto-generated method stub
        ITestListener.super.onTestFailedWithTimeout(result);
    }

    @Override
    public void onStart(ITestContext context) {
        // TODO Auto-generated method stub
        ITestListener.super.onStart(context);
    }

    @Override
    public void onFinish(ITestContext context) {
        // TODO Auto-generated method stub
        ITestListener.super.onFinish(context);
    }
}

两种方式可以使用listener
第一种是在testng class的类上方添加 @Listeners(demoPakage.listenerDemo.class)

第二种是在testng.xml文件中添加

竟然报错
