Quality Assurance
and Testing Services
for Flawless Software Solutions

...ensure your product success and seamless user experience.


Without continuous quality control conducted by QA engineers, any software will suffer from numerous bugs and crashes. Manual testing and test automation allow developers to prepare products for deployment, ensure the ultimate performance, and seamless user experience. This is a critical process for both large enterprises with thousands of end-users and startups that are just making headway. Quality assurance guarantees launching a stable and reliable software that serves as a solid basis for future upgrades and advances.

Leobit delivers fully managed quality control and testing services that ensure the remarkable quality and efficiency of our client’s products. Our specialists set-up comprehensive testing process starting from requirement analysis up to client acceptance. After the product release, we contribute to the creation of a cost-effective maintenance strategy to assist our clients with software optimization. Our principle is ‘prevention over inspection’, therefore, we build products with quality in mind relying on leading industry standards and testing practices. Our approach is to keep the balance between unit testing, integration testing, functional test automation, and manual testing to achieve the desired quality and performance.


Quality analysis and testing services are a multi-faceted process consisting of numerous subtypes, each of which requires deep expertise and experience. Leobit’s QA team specializes in test automation, functional, regression, exploratory, non-functional, and manual testing as well as software requirements specification elaboration and wireframes prototyping. We select the most effective testing approaches for every project and combine them to achieve the maximum result. The selected QA methodology heavily depends on the scope of the project and the software development stage at which the testing started. Leobit always conducts project analysis, evaluates testing automation opportunities, and software performance indicators before testing. We advise our clients to involve testing specialists as early as possible to reduce the overall development costs and proactively predict any possible issues. Launching testing practices at the project initiation phase, our customers significantly reduce the number of defects and decrease the rework cost in the long-run. To stay competitive in the current market conditions, your company needs to understand that product quality is no less important than its features. To ensure this, Leobit has elaborated the quality assurance procedure with the following stages:
