testng失败自动重试

Posted 2022-03-11 qiaoyeye

使用的监听类有：IRetryAnalyzer、TestListenerAdapter、IAnnotationTransformer

 

public class Retry implements IRetryAnalyzer 

    private int retryCnt = 0;
    private int maxRetryCnt = 1;


    @Override
    public boolean retry(ITestResult iTestResult) 
        if (retryCnt<maxRetryCnt)
            retryCnt++;
            return true;
        
        return false;
    

    // 用于重置retryCnt
    public void reset() 
        retryCnt = 0;
    

 

public class RetryListener implements IAnnotationTransformer 
    @Override
    public void transform(ITestAnnotation iTestAnnotation, Class aClass, Constructor constructor, Method method) 

        IRetryAnalyzer retry = iTestAnnotation.getRetryAnalyzer();
        if (retry == null) 
            iTestAnnotation.setRetryAnalyzer(Retry.class);
        

    

 

/**
 * 使用dataProvider时，每个case运行结束都强制重置重试次数，如果失败，则重试结束后，重置次数
 */
public class TestngListener extends TestListenerAdapter 

    @Override
    public void onTestSuccess(ITestResult tr) 
        super.onTestSuccess(tr);
        // 对于dataProvider的用例，每次成功后，重置Retry次数
        Retry retry = (Retry) tr.getMethod().getRetryAnalyzer();
        retry.reset();
    

    @Override
    public void onTestFailure(ITestResult tr) 
        super.onTestFailure(tr);
        // 对于dataProvider的用例，每次失败后，重置Retry次数
        Retry retry = (Retry) tr.getMethod().getRetryAnalyzer();
        retry.reset();
    

新建测试类

public class MyTest 
    @Test(dataProvider = "d1")
    public void dd(int i) 
        System.out.println("i="+i);
        int count = 0;
        Assert.assertEquals(i,5);
    
    @DataProvider(name="d1")
    public Object[][] aa() 
        return new Object[][] 

                 11,
        ;

    

 

testng的xml文件加入listener

<test name="test">
        <packages>
            <package name="qjf"></package>
        </packages>
    </test>
    <listeners>
        <listener class-name="com.crm.Retry.RetryListener"></listener>
        <listener class-name="com.Retry.TestngListener"></listener>
    </listeners>

运行该xml文件，失败后又重试了1次，重试的那一次背忽略
