Software Testing Tutorial

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.
