Functional Testing Services

Lightpoint QA team provides functional testing services to ensure your software solution meets both technical and business requirements. Our QA engineers perform testing of the software features, user interfaces, and system interactions, identifying defects or deviations from the desired behavior. As a result, we verify that the software works as intended and provides a seamless user experience.

Types of Functional Software Testing We Perform

We provide QA services including exhaustive coverage, various testing levels and aspects of functionality, and it’s a continuous process, adaptable to changing project needs and requirements. Thus, we aim to deliver reliable, high-quality software that meets business objectives and user expectations. Below are the QA testing types that we typically conduct, depending on software layers, testing tasks, depth of access to the code, and usage of automation tools.

Manual testing

Our QA specialists execute test cases without the use of automated tools. They manually validate software functionality, identify defects, and ensure the application meets specified requirements.

Automated testing

Our team applies tools and scripts to automatically execute test cases, comparing actual and expected results and improve test efficiency, repeatability, and coverage, particularly in repetitive and large-scale testing scenarios.

Integration Testing

We assess how different components, modules, or systems interact with each other when integrated.

API Testing

We validate data exchange, request-response behavior, and the integration of APIs with other systems or applications to ensure the reliability and interoperability of APIs in different scenarios.

Database testing

We assess the functionality, performance, and reliability of a database, including verifying data integrity, validating queries, and ensuring proper data retrieval and storage.

UX/UI testing

We evaluate both the user experience and user interface product, including design elements, usability, and user satisfaction to ensure an intuitive, convenient, positive interaction.

Black-box testing

We evaluate the functionality of a software application without considering its internal code or logic. Our QA engineers focus on inputs and outputs to ensure that the system meets specified requirements.

White-box testing

We examine the internal structure and logic of a software application. Our QA specialists assess code paths, conditions, and branches for thorough coverage.

Gray-box testing

We combine elements of both white-box and black-box testing, leveraging partial knowledge of the internal code and assessing the application's functionality, focusing on user perspectives and system interactions.
