TestNG--入門

安裝TestGN

安裝流程

  1. 在eclispe中安裝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.也可以使用鏈接中的方法三， 下載文件 解壓到eclipse安裝包dropins路徑下的新文件夾中

eclipse\dropins\testng-eclipse-6.11\

安裝成功的顯示

創(chuàng)建TestNG project在eclipse

  1. 打開(kāi)eclipse > File > new Project


    step1

  2. 輸入 name 然后 click next , 請(qǐng)不要選擇 finish


    step2

  3. 當(dāng)點(diǎn)擊next之后， 在libraries一欄去添加jar包，由于已經(jīng)將TestNG都添加到eclipse中， 所以不選咋導(dǎo)入額外jar包而是選擇 Add Libraries

    step3

  4. 導(dǎo)入Selenuim的jar包


  5. 導(dǎo)入selenium的jar包
    先去下載jar包并解壓到相關(guān)的文件中， 下載路徑為http://docs.seleniumhq.org/download/
    我自己在project下面創(chuàng)建了一個(gè)lib文件，然后將jar包復(fù)制到該路徑下


    將其導(dǎo)入

創(chuàng)建一個(gè)新的testNG test file


自己設(shè)置packageName和class name

然后就會(huì)生成如下的class

下載與瀏覽器相關(guān)版本的driver， Chrome的網(wǎng)站為https://chromedriver.chromium.org/downloads；注意一定要檢查自己瀏覽器對(duì)應(yīng)的版本

輸入代碼 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();
  }
}

參數(shù)化的使用
代碼如下

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("http://*[@id=\"navbar-brand-centered\"]/ul/li[6]/a")).getText();
              Assert.assertEquals(actualTitle, expectedTitle);
         }
}

priority的數(shù)字越小 優(yōu)先級(jí)越高


使用參數(shù)化xml文件來(lái)運(yùn)行testng中的case

TestNG教程：簡(jiǎn)單實(shí)例

TestNG是一個(gè)自動(dòng)化的測(cè)試框架，其中NG的意思是“Next Generation”；它是收到Junit的啟發(fā)來(lái)創(chuàng)建的。使用TestNG，你可以產(chǎn)生一個(gè)適宜的report，而且容易知道那些case已經(jīng)pass；那些是skip的。
你還可以單獨(dú)去執(zhí)行failed的case，TestNG提供來(lái)一個(gè)選項(xiàng)， 在輸出文件夾中有一個(gè)Testng-failed.xml文件，如果你希望執(zhí)行失敗的case，那你就可以直接去運(yùn)行這個(gè)文件。
除了這些簡(jiǎn)單的概念你能理解， 你也可以學(xué)習(xí)進(jìn)階篇， 如何使用@test標(biāo)簽來(lái)創(chuàng)建一個(gè)測(cè)試方法；如何將這些class轉(zhuǎn)換成測(cè)試集文件， 然后使用命令行和eclipse來(lái)運(yùn)行。

  1. 創(chuàng)建一個(gè)新的TestNG Class： demo2
  2. 代碼如下
    這個(gè)代碼是熟悉常用的groups屬性，將所有的methods添加上相應(yīng)的group信息， 注意其中的beforeGroup和afterGroup也有相應(yīng)的參數(shù) （groups = { }）

如果代碼沒(méi)有指定任何的運(yùn)行設(shè)置屬性， 那么會(huì)按照字母進(jìn)行排序運(yùn)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


生成一個(gè)testng.xml文件 然后添加具體的class 和 group信息


點(diǎn)擊RunAs > Run config > 選擇具體的project 和suit文件 點(diǎn)擊run


testng.xml文件中設(shè)置的dependon

<classes>
<class name="TestGuru99MultipleSession">
<include value="testGuru99TC1" dependsOnMethods=" testGuru99TC2"/>
<include value="testGuru99TC2"/>
</class>

xml文件的層級(jí)結(jié)果

<suite name = ""    parallel="tests">
    <test   name="" >
        <classes>
            <class m=name ="" />
        </classes>
    </test>

    <test    name ="">
        <classes>
            <class name="" />
        </classes>
    </test>
</suite>

TestNG Listeners in Selenium

有兩種主要的Listener： WebDriver Listener 和 TestNG Listener； 主要使用testng lisenter
listeners就是用來(lái)調(diào)整默認(rèn)的TestNG行為的接口，可以用來(lái)自定義report和log。 TestNG本身包含很多l(xiāng)istener

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

ItestListener 為例， 它主要包含下面幾個(gè)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

  1. 創(chuàng)建一個(gè)class 繼承“ITestListener”


  2. source > override/implement methods >



    selectAll and click OK



    于是得到如下：

重寫(xiě)其中的部分代碼

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);
    }
}

兩種方式可以使用listener
第一種是在testng class的類上方添加 @Listeners(demoPakage.listenerDemo.class)


第二種是在testng.xml文件中添加

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="Suite">

<listeners>
  <listener class-name="demoPakage.listenerDemo.class" />
</listeners>

  <test thread-count="5" name="Test">  
    <classes>
      <class name="demoPakage.demo2"/>
    </classes>  
    <groups>                
        <run>   
            <include name="test2" />    
        </run>  
    </groups>   
  </test> <!-- Test -->
</suite> <!-- Suite -->
