What is Web Application Testing? Techniques and Tools

Updated: Sep 13, 2023

Web application testing is a process of testing web-based applications to ensure that they meet functional, security, and performance requirements. It involves a series of tests that are designed to evaluate the functionality, usability, reliability, security, and performance of a web application. The goal of web application testing is to identify and report any defects, bugs, or vulnerabilities in the application before it is released to the public.


Web Application Testing Techniques

Web Application Testing Techniques

1. Functionality Testing of a Website

Functionality Testing of a Website is a process that includes several testing parameters like user interface, APIs, database testing, security testing, client and server testing and basic website functionalities. Functional testing is very convenient and it allows users to perform both manual and automated testing. It is performed to test the functionalities of each feature on the website.


Web-based Testing Activities include:


Test that all links in your web pages are working correctly and make sure there are no broken links. Links to be checked will include –

  • Outgoing links

  • Internal links

  • Anchor Links

  • MailTo Links


Test Forms are working as expected. This will include-

  • Scripting checks on the form are working as expected. For example- if a user does not fill in a mandatory field in a form an error message is shown.

  • Check default values are being populated

  • Once submitted, the data in the forms is submitted to a live database or is linked to a working email address

  • Forms are optimally formatted for better readability


Test Cookies are working as expected. Cookies are small files used by websites to primarily remember active user sessions so you do not need to log in every time you visit a website. Cookie Testing will include

  • Testing cookies (sessions) are deleted either when the cache is cleared or when they reach their expiry.

  • Delete cookies (sessions) and test that login credentials are asked for when you next visit the site.


Test HTML and CSS to ensure that search engines can crawl your site easily. This will include

  • Checking for Syntax Errors

  • Readable Color Schemas

  • Standard Compliance. Ensure standards such as W3C, OASIS, IETF, ISO, ECMA, or WS-I are followed.


Test business workflow– This will include

  • Testing your end–to–end workflow/ business scenarios which takes the user through a series of web pages to complete.

  • Test negative scenarios as well, such that when a user executes an unexpected step, an appropriate error message or help is shown in your web application.


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.


Test the site Navigation:

  • Menus, buttons or Links to different pages on your site should be easily visible and consistent on all webpages

Test the Content:

  • Content should be legible with no spelling or grammatical errors.

  • Images if present should contain an “alt” text


3. Interface Testing:

Three areas to be tested here are – Application, Web and Database Server

  • Application: Test requests are sent correctly to the Database and output on the client side is displayed correctly. Errors if any must be caught by the application and must be only shown to the administrator and not the end user.

  • Web Server: The test Web server is handling all application requests without any service denial.

  • Database Server: Make sure queries sent to the database give the expected results.

Test system response when the connection between the three layers (Application, Web and Database) cannot be established and an appropriate message is shown to the end user.



4. Database Testing:

The database is one critical component of your web application and stress must be laid to test it thoroughly. Testing activities will include-

  • Test if any errors are shown while executing queries

  • Data Integrity is maintained while creating, updating or deleting data in the database.

  • Check the response time of queries and fine-tune them if necessary.

  • Test data retrieved from your database is shown accurately in your web application


5. Compatibility testing.

Compatibility tests ensure that your web application displays correctly across different devices. This would include-

Browser Compatibility Test: The same website in different browsers will display differently. You need to test if your web application is being displayed correctly across browsers, JavaScript, AJAX and if authentication is working fine. You may also check for Mobile Browser Compatibility.


The rendering of web elements like buttons, text fields etc. changes with changes in the Operating System. Make sure your website works fine for various combinations of Operating systems such as Windows, Linux, and Mac and Browsers such as Firefox, Internet Explorer, Safari etc.


6. Performance Testing:

This will ensure your site works under all loads. Software Testing activities will include but not be limited to –

  • Load testing - It is the simplest form of testing conducted to understand the behaviour of the system under a specific load. Load testing will result in measuring important business-critical transactions and load on the database, application server, etc. are also monitored.

  • Stress testing - It is performed to find the upper limit capacity of the system and also to determine how the system performs if the current load goes well above the expected maximum.

  • Soak testing - Soak Testing also known as endurance testing is performed to determine the system parameters under the continuous expected load. During soak tests, the parameters such as memory utilization is monitored to detect memory leaks or other performance issues. The main aim is to discover the system's performance under sustained use.

  • Spike testing - Spike testing is performed by increasing the number of users suddenly by a very large amount and measuring the performance of the system. The main aim is to determine whether the system will be able to sustain the workload.


7. Security testing:

Security Testing is vital for an e-commerce website that stores sensitive customer information like credit cards. Testing Activities will include-

  • Test unauthorized access to secure pages should not be permitted

  • Restricted files should not be downloadable without appropriate access

  • Check sessions are automatically killed after prolonged user inactivity

  • On the use of SSL certificates, the website should re-direct to encrypted SSL pages.


Web Application Testing Tools

Testing tools for web applications increase reliability, reduce downtime and increase ROI. They are different types of tools that help in various web testing activities, from the capture of requirements to test management.
