TestNg失败重试机制

TestNg提供了失败重试接口IRetryAnalyzer，需要实现retry方法：

package com.shunhe.testngprac.retry;

import org.testng.IRetryAnalyzer; import org.testng.ITestResult; /** * 设置testng用例失败重试次数 * Created by shunhe on 2019/2/13. */ public class MyRetryAnalyzer implements IRetryAnalyzer { private int retryCount = 0; private final int MAX_RETRY_COUNT = 3; @Override public boolean retry(ITestResult iTestResult) { if (retryCount < MAX_RETRY_COUNT) { retryCount++; return true; } return false; } }

TestNG中的@Test注解包含参数retryAnalyzer，可以在注解中给定重试分析器，如下：

    @Test(retryAnalyzer = MyRetryAnalyzer.class)
    public void test01() { System.out.println("test01"); Assert.assertTrue(false, "test failed"); }

TestNg程序化调用情况

需要实现接口IAnnotationTransformer中的transform方法，对未设置retryanalyzer的@test方法添加响应的retryanalyzer：

package com.shunhe.testngprac.retry;

import java.lang.reflect.Constructor; import java.lang.reflect.Method; import org.testng.IAnnotationTransformer; import org.testng.IRetryAnalyzer; import org.testng.annotations.ITestAnnotation; /** * 添加重试监听器，如果测试方法中未添加重试分析器，则默认添加MyRetryAnalyzer作为重试分析器 * Created by shunhe on 2019/2/13. */ public class MyRetryListener implements IAnnotationTransformer { @Override public void transform(ITestAnnotation iTestAnnotation, Class aClass, Constructor constructor, Method method) { IRetryAnalyzer retryAnalyzer = iTestAnnotation.getRetryAnalyzer(); if (null == retryAnalyzer) { iTestAnnotation.setRetryAnalyzer(MyRetryAnalyzer.class); } } }

在构造tesng执行对象时，添加响应的listener

 

package com.shunhe.testngprac.controller;

import java.util.ArrayList; import java.util.List; import org.testng.TestNG; import org.testng.xml.XmlClass; import org.testng.xml.XmlSuite; import org.testng.xml.XmlSuite.ParallelMode; import org.testng.xml.XmlTest; /** * Created by shunhe on 2019/2/13. */ public class TestNgController { /** * TestNG测试程序化调用 */ public void executeTests() { //构建testng.xml内存对象 try { List<XmlSuite> suites = new ArrayList<XmlSuite>(); XmlSuite suite = new XmlSuite(); suite.setName("TestNG Retry Test"); //添加失败重试 List<String> suiteListeners = new ArrayList<String>(); //添加重试监听器 suiteListeners.add("com.shunhe.testngprac.retry.MyRetryListener"); suite.setListeners(suiteListeners); //类级别的并发 suite.setParallel(ParallelMode.CLASSES); suites.add(suite); XmlTest test = new XmlTest(suite); test.setName("TestNG Retry Test"); //添加将要执行的用例 List<XmlClass> classes = new ArrayList<XmlClass>(); XmlClass testClass = new XmlClass("com.shunhe.testngprac.tests.DemoTest01"); classes.add(testClass); test.setXmlClasses(classes); //TestNG程序化调用 TestNG testNG = new TestNG(); testNG.setXmlSuites(suites); testNG.run(); } catch (Exception e) { System.out.println("测试用例执行失败： " + e.getMessage()); e.printStackTrace(); } } public static void main(String[] args){ TestNgController testNgController = new TestNgController(); testNgController.executeTests(); } }
