Functional Testing and Manual QA Services

Driven by pre-established feature specifications, functional testing approaches software from the user’s point of view. A must-have for every project, it covers 95% of product quality requirements and expectations.

Nix-Dev’s QA and testing teams follow a well-defined process that has been developed and honed over the years. Our experts devise the optimum QA strategy for the project, handpick the right software tools, and plan the required testing activities.

Our functional testing team then develops extensive test cases and checklists, executes them, and analyzes the output. By employing such black-box techniques as equivalence partitioning and boundary value analysis, our testers save time and improve testing efficiency to deliver outstanding results.
