自动化框架

• Base基类：启动、关闭浏览器，定义DataProvider()数据驱动
• 页面：页面元素单独定义，使用xpath、css、js等
• 操作：具有业务意义的操作独立封装
• 案例：按业务需求调用操作
• 工具包：数据库操作封装、读取Excel、字符串处理等
• 监听器
• 截图机制：
  截图时间点：重写TestListenerAdapter接口中的onTestFailure、onTestSkipped方法；
  （注：TestListenerAdapter实际实现的是 ITestListener，直接实现 ITestListener也可以）
  截图方法：

File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE);
filePath = "result/test-report/screenshot/"+ fileName + ".jpg";

• 重试机制：重写TestNG IRetryAnalyzer接口retry方法。重写IAnnotationTransformer接口transform方法检查是否有getRetryAnalyzer，如果没有，定义为自定义的analyzer。
  （注：IAnnotationTransformer用来修改@test注解，IAnnotationTransformer2用来修改@DataProvider, @Factory 以及 @Configuration）

• 报告部分：重写TestNG IReporter接口generateReport方法，testng.xml文件中配置listener

UI自动化截图

File screenshot = ((TakesScreenshot) driver).getScreenshotAs(OutputType.***FILE***);

public class TestResultListener extends TestListenerAdapter {

    private static Logger logger = Logger.getLogger(TestResultListener.class.getName());
    protected ITestContext testContext = null; 
    String  browser = null;

    @Override
    public void onStart(ITestContext testContext) { 
        this.testContext = testContext;
        browser = String.valueOf(testContext.getCurrentXmlTest().getParameter("browserName"));
        super.onStart(testContext);
    }

    @Override

失败用例重新运行

        LogConfiguration.initLog("TestngRetryPage_");
    }
    private static Logger logger = Logger.getLogger(TestngRetry.class);

    private static int maxRetryCount;

    static {
        ConfigReader config = ConfigReader.getInstance();
        maxRetryCount = config.getRetryCount();
        logger.info("RetryCount=" + maxRetryCount);
        logger.info("SourceDir=" + config.getSourceCodeDir());
        logger.info("SourceEncoding=" + config.getSrouceCodeEncoding());
    }

    public boolean retry(ITestResult result) {
        if (retryCount <= maxRetryCount) {
            String message = "Retry for： [" + result.getName() + "] on class [" + result.getTestClass().getName() + "] retry " + retryCount + " times";
            logger.info(message);
            Reporter.setCurrentTestResult(result);
            Reporter.log("RunCount=" + (retryCount + 1));
            retryCount++;
            return true;
