前言  
TestNG提供了很多断言方法 大部分断言失败后会报exception而终止进程，在实际的测试中这样的做法是不可行的

2：如何做到断言失败不中断执行  
2.1：创建监听器

package framework;
    
    
    import java.util.ArrayList;
    import java.util.List;
    
    import org.testng.ITestResult;
    import org.testng.TestListenerAdapter;
     
    public class AssertListener extends TestListenerAdapter {
     
        @Override
        public void onTestStart(ITestResult result) {
            Assertion.flag = true;       
            Assertion.errors.clear();
        }
         
        @Override
        public void onTestFailure(ITestResult tr) {
            this.handleAssertion(tr);
        }
         
        @Override
        public void onTestSkipped(ITestResult tr) {
            this.handleAssertion(tr);
        }
         
        @Override
        public void onTestSuccess(ITestResult tr) {
            this.handleAssertion(tr);
        }
         
        private int index = 0;
         
        private void handleAssertion(ITestResult tr){
            if(!Assertion.flag){
                Throwable throwable = tr.getThrowable();           
                if(throwable==null){
                    throwable = new Throwable();
                }           
                StackTraceElement[] traces = throwable.getStackTrace();
                StackTraceElement[] alltrace = new StackTraceElement[0];           
                for (Error e : Assertion.errors) {
                    StackTraceElement[] errorTraces = e.getStackTrace();
                    StackTraceElement[] et = this.getKeyStackTrace(tr, errorTraces);
                    StackTraceElement[] message = new StackTraceElement[]{new StackTraceElement("message : "+e.getMessage()+" in method : ", tr.getMethod().getMethodName(), tr.getTestClass().getRealClass().getSimpleName(), index)};
                    index = 0;
                    alltrace = this.merge(alltrace, message);
                    alltrace = this.merge(alltrace, et);
                }
                if(traces!=null){
                    traces = this.getKeyStackTrace(tr, traces);
                    alltrace = this.merge(alltrace, traces);
                }           
                throwable.setStackTrace(alltrace);
                tr.setThrowable(throwable);
                Assertion.flag = true;   
                Assertion.errors.clear();
                tr.setStatus(ITestResult.FAILURE);           
            }
        }
         
        private StackTraceElement[] getKeyStackTrace(ITestResult tr, StackTraceElement[] stackTraceElements){
            List<StackTraceElement> ets = new ArrayList<StackTraceElement>();
            for (StackTraceElement stackTraceElement : stackTraceElements) {           
                if(stackTraceElement.getClassName().equals(tr.getTestClass().getName())){               
                    ets.add(stackTraceElement);
                    index = stackTraceElement.getLineNumber();
                }
            }
            StackTraceElement[] et = new StackTraceElement[ets.size()];
            for (int i = 0; i < et.length; i++) {
                et[i] = ets.get(i);
            }
            return et;
        }
         
        private StackTraceElement[] merge(StackTraceElement[] traces1, StackTraceElement[] traces2){
            StackTraceElement[] ste = new StackTraceElement[traces1.length+traces2.length];
            for (int i = 0; i < traces1.length; i++) {
                ste[i] = traces1[i];
            }
            for (int i = 0; i < traces2.length; i++) {
                ste[traces1.length+i] = traces2[i];
            }
            return ste;
        }
    }

2.2：重写断言方法  
Assertion

package framework;
    
    
    import java.util.ArrayList;
    import java.util.List;
     
    import org.testng.Assert;
     
    public class Assertion {
         
        public static boolean flag = true;
         
        public static List<Error> errors = new ArrayList<Error>();
         
        public static void verifyEquals(Object actual, Object expected){
            try{
                Assert.assertEquals(actual, expected);
            }catch(Error e){
                errors.add(e);
                flag = false;
            }
        }
         
        public static void verifyEquals(Object actual, Object expected, String message){
            try{
                Assert.assertEquals(actual, expected, message);
            }catch(Error e){
                errors.add(e);
                flag = false;
            }
        }
        
        public static void verifyNulls(boolean actual, boolean expected){
        	
        	try{
        		
        		Assert.assertEquals(actual, expected);
        		
        	}catch(Error e){
        		
        		errors.add(e);
                flag = false;
        	}
        }
     
        public static void verifyNulls(boolean actual, boolean expected , String msg){
        	
        	try{
        		
        		Assert.assertEquals(actual, expected, msg);
        		
        	}catch(Error e){
        		
        		errors.add(e);
                flag = false;
        	}
        }
        
        //其他需要的断言方法都可以这样写进来.....
    }

//其他需要的断言方法都可以这样写进来.....

2.3：测试testCase  
Case

package testSuite;
    
    import org.testng.annotations.Listeners;
    import org.testng.annotations.Test;
    
    import framework.Assertion;
     
    @Listeners(framework.AssertListener.class)
    public class Testcase {
    	
    	@Test
    	public void Case1(){
    		
    		
    		Assertion.verifyEquals(1, 1);
    		
    		System.out.println("=========Case1=======");
    		
    	}
    	
    	@Test
    	public void Case2(){
    		
    		Assertion.verifyEquals(1, 2);
    		
    		System.out.println("=========Case2=======");
    		
    	}
    	
    	@Test
    	public void Case3(){
    		
    		Assertion.verifyEquals(1, 2);
    		
    		System.out.println("=========Case3=======");
    		
    	}
     
    }

package testSuite;
    
    import java.io.IOException;
    
    
    import org.openqa.selenium.By;
    import org.openqa.selenium.WebDriver;
    import org.openqa.selenium.support.PageFactory;
    import org.testng.annotations.AfterClass;
    import org.testng.annotations.BeforeClass;
    import org.testng.annotations.Listeners;
    import org.testng.annotations.Test;
    
    import framework.Assertion;
    import framework.BrowserEngine;
    import pageObject.LoginPage365;
    import pageObject.functions.Login365;
    
    @Listeners(framework.AssertListener.class)
    public class Test_Login{
    	
    	public static WebDriver driver;
    	BrowserEngine bb = new BrowserEngine();
    	@BeforeClass
    	public void setUp365() throws IOException{
    		Login365 ll = new Login365();
    		ll.initSetup365();
    //		ll.loginValid365();
    		driver = Login365.driver;
    	}
    	
    	
    	
    	@Test
    	public void testLogin1() throws InterruptedException{
    		LoginPage365 lo = PageFactory.initElements(driver, LoginPage365.class);
    		lo.login365("18500592094", "123456");
    //		断言
    		String err = driver.findElement(By.xpath("//*[@id=\"new_login_error\"]")).getText();//获取对应参数,text
    		Assertion.verifyEquals(err, "用户名或密码不正确。");
    		System.out.println("=========Case1=======");
    	}
    	
    	@Test
    	public void testLogin2() throws InterruptedException{
    		LoginPage365 lo = PageFactory.initElements(driver, LoginPage365.class);
    		lo.login365("111111555", "123456");
    //		断言
    		String err = driver.findElement(By.xpath("//*[@id=\"new_login_error\"]")).getText();
    		Assertion.verifyEquals(err, "用户名或密码不正确。");
    		System.out.println("=========Case2=======");
    	}
    	
    	@Test
    	public void testLogin3() throws InterruptedException{
    		LoginPage365 lo = PageFactory.initElements(driver, LoginPage365.class);
    		lo.login365("18500592094", "123saiya");
    		
    		String err = driver.findElement(By.xpath("/html/body/div[4]/div/a[10]")).getText();
    		Assertion.verifyEquals(err, "免费sdfdsf房源");
    		System.out.println("=========Case3=======");
    	}
    	
    
    
    	@AfterClass
    	public void tearDown() throws InterruptedException{
    		Thread.sleep(3000);
    		BrowserEngine bro = new BrowserEngine();
    		bro.tearDown();
    	}
    }

2.4:执行结果

3：如果是testng.xml如何操作？  
1：Case中不写@Listeners(ListenerPackage.AssertListener.class)  
2：testng.xml的配置（还是参考2）  
<?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">  
<suite name="Suite">  
    <listeners>  
        <listener class-name="ListenerPackage.AssertListener"></listener>  
    </listeners>  
    <test name="Test1">  
        <classes>  
              
            <class name="Case.TestCase">  
                <methods>  
                    <include name="Case1"></include>  
                </methods>  
            </class>  
        </classes>  
    </test>   
    <test name="Test2">  
        <classes>  
              
            <class name="Case.TestCase">  
                <methods>  
                    <include name="Case2"></include>  
                </methods>  
            </class>  
        </classes>  
    </test>   
    <test name="Test3">  
        <classes>  
              
            <class name="Case.TestCase">  
                <methods>  
                    <include name="Case3"></include>  
                </methods>  
            </class>  
        </classes>  
    </test>   
</suite>
