Planning to launch a web application? No doubt, you are well aware of the development and design requirements along with the latest technological trends. But are you prepared for the comprehensive web app testing before the launch? Mostly, software testing is overlooked, as only minimal testing is conducted.
However, web app testing is the most important consideration of the SDLC process, and it should not be overlooked at any cost. If you want your users to have the best experience with your app, make sure it undergoes a complete set of tests, starting from functional to end-to-end testing.
Web application testing is highly essential in order to connect users with businesses, offering them a seamless user experience. When the app undergoes functionality, security, and usability, it results in a high-quality product. Comprehensive web app testing prevents potential issues such as poor user experience, broken functionalities, or vulnerabilities in security features before the market launch.
The demand for software tests is now propelling at a rapid rate. The software testing market has surpassed the valuation of $45 billion in size, highlighting its major role. This global software testing market is all set to reach a valuation of $109.5 billion by 2027.
Businesses planning to launch their app must be aware of various types of testing and its prime purposes. For an in-depth testing approach, it is better to invest in web application testing services.
The purpose of today’s post is to help businesses understand major types of web app testing.

1. Functional Testing
Functional testing is the foremost mandatory method to ensure that the app’s features meet functional requirements. The tester checks that each feature of the app works as required. The functional testing process involves the app’s input and output. In addition, it includes user interaction, data manipulation, and the app’s response to desired scenarios.
Types of Functional Testing:
- Unit Testing: Each of the app’s components or modules undergo testing. This testing process involves assessing the smallest unit of code in the application.
- Integration Testing: This testing is done by web application testing services to check the interactions between the incorporated components. It ensures that the integrated design elements and features are functional correctly.
- Smoke Testing: This is a rapid test that examines how the basic functionalities of the app work. Smoke testing usually involves verification of critical software functions before moving on to in-depth testing.
- Sanity Testing: It is a form of narrow testing that focuses on specific functionalities after making certain changes. It instantly examines whether the core features of your web app are functioning properly.
- Regression Testing: This is a specific functional test to ensure that code changes are not affecting the existing functionality. If the tester finds any effect due to code changes, it is fixed immediately.
Tools Used: The web app performance testing tools that are best for conducting all types of functional tests are:
- Selenium – Automating web app testing
- Cypress – Modern web applications
- QTP – Automated functional testing
2. Usability Testing
The ultimate goal behind web app development is to offer a great user experience with seamless navigation to the end-users. So, before you market your app, it has to undergo usability testing to examine its user-friendliness and intuitiveness. Usability testing is a primary software testing that is used to check the app’s response to the user’s action. You need to understand the tips for selecting a reliable web app testing service to move ahead and hire the right provider.
Key Aspects:
- Ease of Use: The main thing to confirm is that the app’s interface is intuitive. It primarily focuses on how effortlessly users can complete their tasks and interact with the app. The tester takes feedback from users during testing, which lets them identify key areas for improvement in design, features, and functionality.

Types of Performance Testing:
- Load Testing: Testers conduct load tests to check how the app is working under expected traffic loads. The test is conducted in real-world load conditions.
- Stress Testing: The stress test assesses the app’s robustness by letting it perform beyond its operational capacity. This performance test is to figure out how much stress the app can handle.
- Scalability Testing: The test ensures that the application can manage high traffic and growing data volume without compromising performance. It evaluates how well the app adapts to heavy loads and identifies any potential limitations.
- Spike Testing: The spike tests evaluate the system’s stability by simulating sudden spikes in load. It determines how well the system handles unexpected traffic surges and whether it can recover smoothly.
Tools Used:
- Jmeter – Open-source performance testing tool
- LoadRunner – It is best to find performance issues and bottlenecks.
- BlazeMeter – Realistic load testing
- WebLOAD – Load and stress testing
4. Compatibility Testing
Compatibility testing is another primary software test that examines the app’s functionality across multiple platforms, operating systems, and browsers to detect potential discrepancies. This test verifies that your app is performing effectively in its intended environments.
Key Aspects:
- Cross-Browser Testing: This compatibility test is conducted to ensure that the application functions as desired in different browsers. The testers of the web application testing company check its working functionality in Chrome, Firefox, and Safari.
- Cross-Device Testing: The test shows that the web app is responsive across multiple devices, such as desktops, tablets, and smartphones. This specific technique assesses that your web app fits required screen resolutions and sizes without any issues, offering the best user experience.
