WebPage Performance Testing

What is Webpage Performance Testing?

Web Performance Testing is executed to provide accurate information on the readiness of an application through testing the web site and monitoring the server side application. This is done by simulating load as close as possible to the real conditions in order to evaluate if the application will support the expected load.

How does INGenious perform Webpage Performance Tests?

INGenious can analyse the performance of a Web Page by using some built-in javascript based actions. The framework generates an information-rich performance report which is very handy to visualize which resource consumed how much time.

Additionally, there is an option to compare HAR files and even set benchmarks.

HAR is the short form for HTTP ARchive format, which tracks all the logging of web browser's interaction with a site. HAR files can be a requirement for troubleshooting issues specifically for problems such as performance and page rendering.

Actions

Browser 🟢 capturePageTimings %dynamicVar% PageName ⬅ Input from variable 
    var pt=performance.timing;
    var t={};
    t.title=document.title;
    t.url=window.location.href;
    for(var k in pt){t[k]=pt[k];}
    t.toJSON=undefined;

            Report.updateTestLog(Action, "Cookies Cleared", Status.DONE);
        } catch (Exception e) {

  • Once this configuration is saved, run your test set and post the execution you will get a report.Expand the report by clicking on your test case and this time the console icon on the bottom right will change into the Performance Report icon.

  • To launch the performance report click on the Performance Report icon.

perf2

  • The table and graph view contains the har files generated post execution.Click on them to get the various page and resource timings parameters captured by the capturePageTimings action.

Compare Har Files

  • To Compare your Har files, navigate to Tools Har Compare and you will be redirected to the Har Comparator site.

perf4

  • Here you compare the Har files that you have in your project.

perf5

  • You can and also set benchmarks for achieving standards.
