如何为cucumber测试框架生成程度报告

Question

如何为cucumber testng framework生成扩展报告，以便在每个场景失败时都能捕获屏幕截图，而无需在步骤定义文件中的每个场景中重复代码

我已经使用Cucumber Testng设置了测试框架。然而，我需要数据块报告，但不确定如何通过testNG runner类实现它，而不必在步骤定义的每个场景中实际重复代码。因此，我们的想法是在一个地方编写代码，就像使用cucumber钩子一样，它将在每个场景中运行。

I Have already tried the approach with TestNG listener with Extent report but with this the drawback is I have to write the code every time for each and every scenario. LIke below I have ITestListnerImpl.java, ExtentReportListner and YouTubeChannelValidationStepDef where for each scenario I have to repeat the loginfo and screencapture methods

代码： ItestListerner.java

package com.testuatomation.Listeners;

import org.testng.ITestContext;
import org.testng.ITestListener;
import org.testng.ITestResult;

import com.aventstack.extentreports.ExtentReports;

public class ITestListenerImpl extends ExtentReportListener implements ITestListener {

    private static ExtentReports extent;

    @Override
    public void onFinish(ITestContext arg0) {
        // TODO Auto-generated method stub
        extent.flush();
        System.out.println("Execution completed on UAT env ......");                
    }

    @Override
    public void onStart(ITestContext arg0) {
        // TODO Auto-generated method stub
        extent = setUp();           
        System.out.println("Execution started on UAT env ......");          
    }

    @Override
    public void onTestFailedButWithinSuccessPercentage(ITestResult arg0){
        // TODO Auto-generated method stub          
    }

    @Override
    public void onTestFailure(ITestResult arg0) {
        // TODO Auto-generated method stub
        System.out.println("FAILURE");          
    }

    @Override
    public void onTestSkipped(ITestResult arg0) {
        System.out.println("SKIP");

    }

    @Override
    public void onTestStart(ITestResult arg0) {
        System.out.println("STARTED");

    }

    @Override
    public void onTestSuccess(ITestResult arg0) {
        // TODO Auto-generated method stub
        System.out.println("PASS-----");    
    }       

}

Answer 1

你的lofInfo是空的，应该是这样的

    @Then("Open Chrome browser with URL")
    public void open_Chrome_browser_with_URL() {
        try {
            logInfo = test.createNode(new GherkinKeyword("Then"), "open_Chrome_browser_with_URL");

//YOUR CODE HERE

            logInfo.pass("Chrome opens URL");
        }
        catch (AssertionError | Exception e) {testStepHandle("FAIL", d, logInfo, e);
}
    }
