Non-Functional Software Testing

Non-Functional Software Testing

Quality Assurance of digital solutions requires a strong focus on the verification and validation of those systems against Non-Functional Requirements (NFRs), which represent quality aspects of the system such as performance, security, usability, and compatibility. Unlike functional requirements, NFRs represent the quality attributes of the system as a whole and directly affect the overall experience of end users.

Performance Testing

Our Performance Testing Center of Excellence offers proven test methodologies, monitoring strategies, performance diagnosis capabilities, solution accelerators, and expertise across several popular commercial and open-source tools to certify applications for performance, scalability, and capacity characteristics. Our performance testing and engineering solutions cover a wide range of applications including Web, mobile, client-server, and packaged enterprise solutions such as SAP, among others.

Our end-to-end “performance assurance” methodology goes beyond performance testing to include client-side (browser/device) performance analysis, workload modeling using scientific principles, performance modeling, server monitoring, code and database profiling, performance diagnosis and optimization, and capacity planning.

Know our Capabilities

Security Testing

The IT world is increasingly threatened by hackers every day. The need of the hour is for enterprises to protect their software systems against sophisticated and malicious threats such as database injections, cross-site scripting, and other such methods.


Our team constantly monitors latest security threats and areas of vulnerabilities in software applications. We have sound knowledge in testing the security of software applications like web & mobile applications and products across verticals.

Security Testing Center of Excellence

Our security testing CoE consists of specialists who keep themselves up to date about the latest vulnerabilities and threats, tools, and methods to counter security attacks. With our certified penetration testers, who are experts in performing red team exercises, we have helped many clients secure their digital products and infrastructure.


Our security testing services include security assessments and compliance audits. We perform automated scanning, vulnerability assessments, and penetration testing to help ensure security of applications and networks as per cybersecurity standards. Our compliance audit services help review the adherence of information security policies and procedures as per compliance guidelines.

Usability Testing

Usability testing ensures that applications are easy to use and match customer expectations and intentions, thus improving customer satisfaction and retention. This also decreases cost on support and modifications. Our non-functional software testing experts evaluate user experience, interaction design, information architecture and management of content, knowledge, and brand.

Customer-centric usability software testing

With strong user-validated product designs, we enable the fastest test cases on client products. Our application usability testing experts can gauge the level and extent to which the product idea has been delivered within the paper representation / prototype.Our UX architects, engineers, or strategists understand that user interface testing is the crossover between visual design (product look and feel) and interaction design (how the product line works).

Test cases capture detailed information on how users will behave with the portal/product. The awareness of UX/UI tests will formulate future requirements for product functionality. Usability software testing services save our clients from incurring heavy maintenance costs, loss of time and money during development stages.


Our innovative usability software testing services work on putting together specific, organized UI/UX tests, that help route users towards the product using targeted pathways. Feedback gathering and evaluation are part of the initial phase. Measured delivery and matching user expectations, while validating user actions/assumptions are both critical in the design phase.
