Our web application testing services

Functional testing

Functional testing covers several areas of QA, making sure that each page of your website or web app is loading correctly, the UX is smooth, and different usage scenarios can be executed without errors and frustration.

Performance testing

App and website testing services should include a process of checking the speed and scalability. To guarantee that an app or site can handle an influx of users, it’s important to test its performance in different scenarios of irregular workloads.

Manual testing

Manual testing is essential for evaluating real-user experience and catching issues that automation often misses. Our QA engineers perform exploratory testing, verify UI consistency, validate complex flows, and check integrations from an end-user perspective.

Automation testing

Automation testing improves release speed by reducing regression risk and providing fast feedback to your team. We define what to automate for maximum ROI,which enables shorter release cycles, consistent quality, and fewer last-minute surprises before deployment.

Accessibility testing

Accessibility testing ensures your web application is usable for all audiences and meets common accessibility expectations. We evaluate keyboard navigation, screen-reader behavior, contrast and focus states, and form and error messaging clarity.

Dedicated testing team

We can build a dedicated testing team aligned with your roadmap. You’ll get consistent test coverage, stable processes, clear KPIs, and a team that understands your domain and release cadence.

Binary Studio’s awards

Web QA service FAQ

Why do I need web app testing?

Testing is a crucial aspect of any software product development. In the case of websites or web applications, it helps ensure that the end product meets all the functional requirements, its features and interactive elements work correctly across different environments, its UI/UX components are clear, it can handle high user traffic and easily scale, and the data if features is stored securely and can’t be accessed without authorization.
What types of testing do you perform?

Our website QA testing services include any type of testing that can be required, be it functional, performance, integration, security, or other testing. The scope of work will depend on your particular product and requirements. Also, we can build a testing strategy and choose suitable testing types based on the product specification: for instance, if you need ERP system testing or SaaS web app testing.

When should I include testing in the development process?

Ideally, testing should be on the agenda from the very start of development. But if you don’t have a dedicated team with both developers and testers, you can partner with a web app testing company that will cover your QA needs at any stage of the product’s completion. If you’re not sure about how web testing should be integrated into your project, drop us a line—and we’ll explain all the nuances during a free consultation call.
How do I know that my web app is ready for release?

We prepare a web app for the launch after rounds of testing, when there are no more bugs, all the features work as expected, and all the usage scenarios are performed without any issues. It’s important to include real user feedback in the QA process and address concerns or recommendations from real users before releasing the app or website. However, note that you’ll need some continuous maintenance of a web-based product, as issues might arise connected to the server, cloud services, new user interactions, etc.
