JAVA结合testng断言verify(断言失败不中断继续执行)

原理：

1.自已构造一个断言类，把Assert.assertEquals给try catch住。

2.利用testng的监听类在测试方法运行结束后进行分析。

代码：

断言类：

package com.demo;

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;
		}
	}

}

 监听类：

package com.demo;

import java.util.ArrayList;
import java.util.List;

import org.testng.ITestResult;
import org.testng.TestListenerAdapter;

public class AssertionListener 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;
    }
}

 测试类：

package com.demo;

import org.testng.annotations.Listeners;
import org.testng.annotations.Test;

@Listeners({com.demo.AssertionListener.class})
public class Test14 {

	
	@Test
	public void testAssert3(){	
		Assertion.verifyEquals(2, 3, "比较两个数是否相等：");	
		Assertion.verifyEquals(1, 2, "比较两个数是否相等：");		
	}
	
	@Test
	public void testAssert4(){	
		Assertion.verifyEquals(4, 3, "比较两个数是否相等：");	
		Assertion.verifyEquals(2, 2, "比较两个数是否相等：");		
	}

}
