In today's highly competitive and constantly evolving web-based scenarios, it's more crucial than ever for companies and organizations to thoroughly test their web-based applications before releasing their website. Organizations will ensure that their software can run smoothly and that end-users can approve them by undertaking comprehensive web application testing.
When it comes to testing web apps for consistency and functionality, you can use a number of testing methodologies or techniques. Such testing techniques evaluate not only the consistency of a web application, but also its browser stability, load testing, scalability testing, stress testing, and other variables.
Web application testing is a mandatory skill for Software test engineers these days. The advancement in web technologies like Java/J2EE, JavaScript, HTML5, PHP, AngularJS, Node.js, and React is the leading force driving the companies to produce more and more web applications.
Bundled with many capabilities, a Web Application had to pass through a series of validations to ensure quality. Not only all the UI flows require testing but also the interfaces like SOAP and REST APIs which enable customization at the client end.
As a consequence, a tester may use any or all of the web application testing techniques mentioned below. These are tried-and-true approaches that are commonly used in the industry and are well-known for achieving results.
There are many different types of website testing, too many to cover here. There are technical tests that assess the integrity of your server and database, and security tests to eliminate fraud.
In this post, we’re going to discuss a few basic testing methodologies for testing web apps.
Few of the basic testing techniques for web applications:
1. Functionality Testing
Test for – all the links in web pages, database connection, forms used for submitting or getting information from the user in the web pages, Cookie testing, etc. Links to be checked will include -
- Outgoing links
- Internal links
- Anchor Links
- Mail To Links
Tools that can be used: QTP , IBM Rational , Selenium
2. Usability Testing
Usability Testing has now become a vital part of any web based project. It can be carried out by testers like you or a small focus group similar to the target audience of the web application. The user interface of the application should conform to the standards in order to make it user-friendly and efficient.
When designing a web application, it's important to adhere to all global protocols and web standards. Usability testing is necessary for applications that seek to automate a manual operation.
However, when approaching usability testing, some important considerations such as proper navigation, site chart, avoiding over-crowded content, and more should be kept in mind.

3. Web UI Testing
The server-side interface should be reviewed during web testing. This can be achieved by ensuring that the correspondence is carried out correctly. The server's compatibility with software, hardware, the network, and the database should all be reviewed.
The main interfaces are:
- Web server and application server interfaces.
- Application server and Database server interface.
Check what happens if the user interrupts any transaction in-between? Check what happens if the connection to the webserver is reset in between?
Tools that can be used: AlertFox, Ranorex
4. Compatibility Testing
Browser Compatibility Test is the most influencing part of website testing. Different browsers have different configurations and settings that your web page should be compatible with. You need to test if your web application is being displayed correctly across browsers, JavaScript, AJAX and authentication is working fine. You may also check for Mobile Browser Compatibility. We may also check web application is responsive and works on devices of different shapes and sizes.
Test web applications on different browsers like Internet Explorer, Firefox, Netscape Navigator, AOL, Safari, Opera browsers with different versions.

5. Performance Testing
Performance testing intends to trespass the boundaries of standard testing and aims to verify the application response time and throughput under various load conditions. In this testing method, website is usually tested for its functionality on different operating system, hardware platforms and more. The web application should sustain a heavy load. Web performance testing should include:
- Web Load Testing
- Web Stress Testing
Web Stress Testing aims to test the application beyond the expected maximum load. With it, we can determine the threshold limit of the system and also document the behavior when it goes past the limit.
Quality testing can be used to assess the scalability of a website or to compare the performance of third-party items such as servers and middleware in the sense of a future purchase. To reduce load times, make sure optimization techniques including g-zip compression, browser and server side cache are allowed.
Tools that can be used: Loadrunner, JMeter
6. Security Testing
Tools that can be used: Babel Enterprise, BFBTester and CROSS
7. Database Testing
Database is one critical component of your web application and stress must be laid to test it thoroughly. The database should respond to all queries sent via UI or APIs. And any change in data should not violate the data integrity. Also, need to check if the data returned from the database is displaying correctly or not. Next, it should not permit any direct access instead should return a proper access denial message.
Tools that can be used: QTP, Selenium
8. Crowd Testing
You'll choose a large group of people (crowd) to run tests that would otherwise be run by a small group of people in the business. Crowdsourced research is a new and exciting phenomenon that can help uncover many previously undetected flaws.
Tools that can be used: People like you and me. And there are a lot of them!
Key Takeaways
This concludes the tutorial. It includes almost all testing types applicable to your web application. Well, these are just a few major web test automation tools you can use to test your web applications, but there are hundreds of other tools you can google over the web as per your needs.
