Software testing is an important part of the software development lifecycle that involves verifying and validating whether a software application works as expected. It ensures reliable, correct, secure, and high-performing software across web, mobile applications, cloud, and CI/CD pipelines in DevOps.
- Detect bugs before release.
- Ensure software meets requirements.
- Improve product quality and reliability.
- Reduce the cost of fixing issues later.
- Validate performance, security, and usability.
Software Testing Basics
This section introduces the fundamental concepts of software testing, including key definitions, principles, and lifecycle models. It helps beginners understand how testing fits into the overall software development process.
