Types of Software Testing:

1. Manual Testing The tester checks the software by using it like a real user. Click buttons Fill forms Check outputs 🤡 Example: Opening a website, logging in, and checking if all pages load correctly.

2. Automation Testing Tests are run using tools or scripts instead of humans. Fast and repeatable Used for large or repeated tasks 🗿 Example: Automatically testing login with 100 different usernames and passwords.

3. Unit Testing Small parts of the code are tested individually. Done by developers Focuses on functions or methods 📌 Example: Testing a function that calculates total bill amount.

4. Integration Testing Checks if different modules work well together. Data flow between components 📌 Example: Login page connecting correctly with the database.

5. System Testing Tests the complete application as a whole. End-to-end testing 📌 Example: From login → order → payment → logout.

6. Acceptance Testing Checks if the software meets user or business requirements. Done before final release 📌 Example: Client checks if all requested features are present.

7. Regression Testing Ensures new changes didn’t break existing features. Very common in real projects 📌 Example: After adding a new payment option, checking login and cart still work.

8. Smoke Testing Quick testing to see if the main features work. Done after a new build 📌 Example: App opens, login works, main page loads.

9. Sanity Testing Focused testing after small changes. Narrow and quick 📌 Example: After fixing login bug, only login-related checks are done.

10. Performance Testing Checks speed, load, and stability. Load testing Stress testing 📌 Example: Checking if a website works with 10,000 users at once.
