Software Testing Basics

Types of Software Testing Methods

In software development, testing is vital for quality and reliability. It falls into two main categories: manual and automated testing5. Manual testing involves human testers directly interacting with the application. Automated testing uses scripts and tools to execute the testing process5.

Functional testing is a key part of software testing, focusing on verifying the software’s functionality against the given requirements. This includes unit, integration, and system testing5. Non-functional testing, on the other hand, assesses the system’s performance, usability, and security. It ensures the software meets the desired standards5.

Black-box testing examines the software’s inputs and outputs without access to the internal structure. White-box testing analyzes the application’s internal code and logic6. Gray-box testing combines aspects of both, offering a balanced approach6.

Regression testing is crucial, ensuring new changes or updates do not introduce issues or break existing functionality6. Continuous integration tools and cloud-based services automate test execution. They ensure changes trigger necessary testing protocols5.

The ultimate goal is to deliver high-quality, secure, and reliable software that meets user needs6. Software testing is a critical part of the development workflow. It serves as a final checkpoint before deployment to production5.
