TestNG 中失败用例重跑机制

1、首先编写Java类实现IRetryAnalyzer接口

public class OverrideRetry implements IRetryAnalyzer {
    private int count = 1;
    private int max_count = 3;

    @Override
    public boolean retry(ITestResult result) {
        System.out.println("执行用例："+result.getName()+"，第"+count+"次失败");
        if (count < max_count) {
            count++;
            return true;
        }
        return false;
    }
}

2.编写重跑监听

public class RetryListener implements IAnnotationTransformer {

public void transform(ITestAnnotation annotation, Class testClass,Constructor testConstructor, Method testMethod) {

IRetryAnalyzer retry = annotation.getRetryAnalyzer();
if (retry == null) {
annotation.setRetryAnalyzer(OverrideRetry .class);  // 这个类名一定要和上方的对上

}
}
}

testng.xml中加一个监听

   

<listeners>
    <listener class-name="com.traapi.request.Teacher.RetryListener ">
    </listener>
</listeners>

<test name="test">
    <classes>
        <class name="com.traapi.request.Teacher.RetryTest">
            <methods>
                <include name="test1"/>
                <include name="test2"/>
            </methods>
        </class>
    </classes>
</test>

已上 就 可以 实现失败重跑了，但是，用例重跑之后，失败的结果也记录在运行结果中了，测试结果中运行的用例数增加了，不利于我们查看测试结果。因此，我们还需要把重复的用例去掉。 

解决办法就是重写onFinish

   

public class TestngListener extends TestListenerAdapter {

    private static Logger logger = Logger.getLogger(TestngListener.class);

    @Override
    public void onTestFailure(ITestResult tr) {
        super.onTestFailure(tr);
        logger.info(tr.getName() + " Failure");
    }

    @Override
    public void onTestSkipped(ITestResult tr) {
        super.onTestSkipped(tr);
        logger.info(tr.getName() + " Skipped");
    }

    @Override
    public void onTestSuccess(ITestResult tr) {
        super.onTestSuccess(tr);
        logger.info(tr.getName() + " Success");
    }

    @Override
    public void onTestStart(ITestResult tr) {
        super.onTestStart(tr);
        logger.info(tr.getName() + " Start");
    }

    @Override
    public void onFinish(ITestContext testContext) {
        super.onFinish(testContext);
        Iterator<ITestResult> listOfFailedTests = testContext.getFailedTests().getAllResults().iterator();
        while (listOfFailedTests.hasNext()) {
            ITestResult failedTest = (ITestResult) listOfFailedTests.next();
            ITestNGMethod method = failedTest.getMethod();
            if (testContext.getFailedTests().getResults(method).size() > 1) {
                listOfFailedTests.remove();
            } else {
                if (testContext.getPassedTests().getResults(method).size() > 0) {
                    listOfFailedTests.remove();
                }

            }
        }
    }
}

重新添加监听

<suite name="Suite1" verbose="1">
<test name="CheckName">
<classes>
<class name="com.luray.testsuite.CheckStockList" />
</classes>
</test>
<listeners>
<listener class-name="com.luray.testngsetting.RetryListener" />
<listener class-name="com.luray.testngsetting.TestngListener" />
<listener class-name="org.uncommons.reportng.HTMLReporter" />
<listener class-name="org.uncommons.reportng.JUnitXMLReporter" />
</listeners>

</suite>

这次就只记录最后一次结果了

Ok  了
