testng失败自动重试

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>
