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.
