Testing means the process of evaluating a software application to find and fix errors, ensure it behaves as expected, and verify that it meets the specified requirements.
In simpler terms, testing checks:
- Does it work correctly?
- Is it reliable and secure?
- Does it meet user needs?
There are different types of software testing, like:
- Unit Testing: Testing individual components or functions.
- Integration Testing: Checking if different modules work together.
- System Integration Testing (SIT): Testing the entire application as a whole.
- User Acceptance Testing (UAT): Verifying if the software meets the business requirements.
- Regression Testing: Making sure new changes don’t break existing features.
Testing can be manual (done by people) or automated (done by scripts and tools).
