Our Manual Testing Services


Black-Box Testing

Run specification-based testing to examine a specific software level without delving into internal code structure. Black-box tests are highly effective for checking the system's functionality, behavior, and input/output.

White-Box Testing

Delegate structural testing to our manual testing company to check your application's internal structure and code. Mutation, unit, integration, penetration, and other types of white-box tests help continuously improve the code and engineering approaches.

Usability Testing

Evaluate the usability of early design prototypes or test the app at later development stages to ensure it operates as intended. We will run tests to investigate user behavior and gather feedback on ways to enhance the UX.

Accessibility Testing

Use our manual software testing services to flag accessibility issues and fix them to make your app content available and inclusive to everyone. Web and mobile accessibility is essential for quality UX and regulatory compliance.

Compatibility Testing

Verify your app looks and works equally well across different devices, browsers, platforms, and operating systems with compatibility tests. It will save you from disappointed users and unnecessary complaints after the app release.

Performance Testing

Test your software performance under a specific workload to ensure it can withstand the necessary volume of operations. Performance testing measures stability, scalability, reliability, and resource usage as the core markers of optimal app functioning.

First-Rate Testing Services

Binary Studio focuses on software quality, adopts the latest industry approaches, and nurtures our team members’ professional growth to stay among the market leaders. This brings us customer trust and translates into multiple industry-specific awards we are proud to own.

Benefits of Manual Testing


High Accuracy

Thanks to the human touch and judgment, manual testing ensures much better accuracy than predefined automated tests. Manual testers who have checked dozens of similar apps before yours know what to test and how to interpret the results.

Early Detection

Engage QA engineers from the start to detect any issues and discrepancies manually. It will improve the overall quality of your application and allow you to spot and remove bugs before software release to production.

User Perspective

Capture real user experience, gather feedback on the interface, and spot minor inconveniences or usability issues with help of QA engineers who will simulate real interactions with your app while testing.

Cost Effectiveness

Use manual software quality assurance as a more affordable alternative to automated tests. Manual tests are particularly efficient for small projects, development teams with limited budgets, and quick testing implementation with fewer resources.

Testing Flexibility

Get immediate feedback and quickly adapt to project requirements, scope, or test case changes without rewriting test scripts. Manual testing allows you to check how the app works in real time to stay flexible.

Suitable for Complex Scenarios

Adopt manual testing for non-repetitive scenarios and unusual behavior when automated tests are challenging and expensive to implement. Our engineers will leverage their skills and expertise to check the complicated features and the whole system.
