What is Software Testing? (Simple & Interview-Friendly)
Software testing is the process of verifying and validating a software application to ensure it works as expected and meets business requirements.
Simple Interview Example
If a login feature:
- Allows valid users to log in
- Blocks invalid users
- Shows proper error messages
Then the software passes testing for that feature.
In interviews, always keep your answer short, simple, and example-based.
