Web Applications: Testing and Monitoring

By

WEB TESTING
Web testing is a term used to refer to software testing, which deals on web application. Before revealing your web-based system to the general public, a complete testing will enable you address some issues like functionality of the site, number of the users, readiness for expected traffic, handicapped users as well as fully able users, massive spike in user traffic and security of the web application.

WEB APPLICATION DEVELOPMENT TESTING
Any software engineer involved in web building, supporting web-based applications and their maintenance understands the need of testing. Application testing is important in retaining and maintaining a consistence user experience. Various kinds of tests included in web application engineering can be automated using various scripting tools. These tests includes; unit testing, load testing, functional testing, performance testing, acceptance testing, stress testing and regression testing.

WEBSITE MONITORING
This testing is done to verify whether the end user will be able to interact with the website or the web application as per the requirements. Most of the times, website monitoring is used to ensure that performance, functionality and website up-time is as expected. To learn more about ways to implement monitoring on your site, check out Web – Application – Monitoring, a site that helps break down different options based upon strengths and weaknesses.

Companies that monitor websites provide organizations with the ability to monitor websites frequently, how the server is functioning as well as observing how it is responding. Website monitoring is in many instances conducted from different parts of the world to specific websites to pinpoint errors, detect problems related to internet, and internet hop issues.

WEB APPLICATION MONITORING AFTER ITS RELEASE
As a web developer, poor end user experience is with no doubt one of the things you would not want with your web app. Therefore, you should work towards maintaining your users by making sure your website is not broken, is showing the right content and is fast. Web application monitoring aids in ensuring these functions at all time.

The Process of Testing and Debugging a Web Application

When you are testing a web application and the test keeps failing, it can be very frustrating. The fix is simple yet complex at the same time. First you should understand why the failure is occurring. The request that appears to be failing is not always the problem. There may be a previous request that is not behaving the same way it did during the initial recording. Dynamic variables, like the session id, of which is hard coded through the requests you make and you will have to modify your requests to not hard code the values.
To debug these interference, you will need to look at the request that is failing and determine which one the error is. There are two that you will commonly see.

The first you should look at is automatic hidden field binding failure. When this happens you will see: “RequestFailed: Context parameter ‘$HIDDEN1.__VIEWSTATE’ not found in test context”. This message is indicating that the web test tried to extract a hidden field called VIEWSTATE from the previous response but was not able to extract it. There are two ways to fix this.

You can visually compare the playback results and make your determination from there of which is very time consuming. The other is the use of a tool called fiddler. This is a proxy recorder and will capture requests, responses, and headers during each recording. You can use this to compare with what the VS web test engine and see what it is submitting, and you will be able to determine if they match. This might be a little overwhelming at first, but once you understand the basics of testing and monitoring web applications, other aspects of the field should begin to make sense.

You should note that this is what has worked for others in these situations and may not fix the problem every time. There are other tools available that will be able to aid you in figuring out what the problem is with your web application. These tools can be found through web engine search.
