There are several stages of testing in the software development life cycle that ensure the quality and functionality of a product. The first phase is , where the software is tested by a limited group of users in a controlled environment. This allows for early detection of bugs and usability issues.
After the Alpha Testing stage, the software moves on to . Here, a larger group of external users is involved, testing the software in a real-world setting. Beta Testing aims to gather feedback, uncover any remaining bugs, and fine-tune the product before its official release.
is the process of testing individual components or units of code to ensure they function as expected. It helps identify and fix bugs early in the development cycle, promoting code reliability and maintainability.
verifies the proper interaction and integration of different modules or components of the software. It checks if the interfaces between these elements function correctly and that data is transferred accurately.
evaluates the complete and integrated system against the specified requirements. It examines whether the software meets functional, non-functional, and business requirements, ensuring that all components work together as intended.
is performed after modifications to existing code or when new features are added. It ensures that the changes do not introduce new bugs or impact the existing functionalities negatively.
evaluates the responsiveness, scalability, and resource usage of the software under different conditions. It measures system performance, such as response time, throughput, and resource utilization, to ensure optimal performance and identify any bottlenecks.
Ensuring the security of software is crucial, which is where comes into play. It assesses the system's vulnerability to potential attacks, tests authentication and authorization mechanisms, and identifies any security loopholes that need to be addressed.
focuses on evaluating the user-friendliness and ease of use of the software. It involves real users performing specific tasks to identify any usability issues, such as confusing interfaces or difficult navigation, providing valuable insights for improvements.
is the final phase of testing before the software is released or deployed. It is performed by the end-users or stakeholders to determine whether the software meets their requirements and is ready for production use.
