Software testing services we provide

Functional testing

Functional testing is aimed at checking the system for compliance with all functional requirements and necessary specifications. This type of testing focuses on checking the main parameters: testing of the essential functions of the application, usability (for example, if the user can move freely and smoothly through the screens), accessibility of the system for the user, and error conditions (if appropriate error messages are displayed).

Non-functional testing

This type of testing is conducted after functional testing because it is intended to verify the system’s readiness by non-functional parameters that are never considered in functional testing. Non-functional testing describes how well the product operates. It tests scalability, reliability, as well as performance, and other non-functional aspects of the system.

Regression testing

This type of testing is aimed at re-testing the functionality of a program and making sure that existing features work correctly, and that recent code changes have not negatively impacted existing features. Often a set of relevant test cases is used, such as test cases with frequent defects, test cases of functionalities and recent changes, test cases of boundary values, and test cases of failure.

Usability testing

Usability testing is designed to assess how user-friendly the system is. It is conducted during the initial design phase to better understand user expectations. The main focus of this testing is the ease of use of the application, element management flexibility, and the ability of the application to perform necessary tasks.

Performance testing

Performance testing identifies possible bottlenecks in software and eliminates them. The main goal of this testing is to check the app’s speed (the app must respond quickly), scalability (the user load software can handle), and stability (the app must remain stable under various loads).

Localization testing

Localization testing checks how well the application functions in a particular location and is adapted to the language and the culture of the users. During this testing, the placement of text fields and buttons, time format, currency, language, email format, etc. are checked. Our highly qualified experts ensure that all elements perfectly match the perception of a particular region.

End-to-end testing

E-2-E testing involves checking the application workflow from start to finish and testing the system for integration, performance, and data integrity. It ensures system quality before testing third-party service integrations. This testing reduces testing effort and costs.

Integration testing

Integration testing involves testing different modules and components of the system by combining them into one group. First, each component is tested separately, and then the interaction of components with each other is checked.

Acceptance testing

Acceptance testing is the final testing in the chain of tests that ensures the high quality of the product. It is performed before the product is released and verifies that the functionality of the system meets all requirements.

Test automation

Test automation facilitates the work of QA specialists because it automates repetitive tests, maximizes test coverage, and allows specialists to focus on more complex tasks. It is up to QA engineers to decide on the rationality of automated tests on a case-by-case basis.

How Much Will a Product QA Phase Cost

According to industry norms, the cost of QA services is 10% of the total budget, and 20% of the budget is spent on bug fixes. The price depends on the team size that performs testing, the type of software, its size, and its complexity. Besides, such things as the cost of poor quality (COPQ), appraisal costs, internal and external failure costs, prevention costs, COQ resources, and COQ and organizational objectives affect the cost of QA.
