**Software Testing Tutorial #22 - Functional Testing vs Non-Functional Testing - Notes**
**Differences Between Functional and Non-Functional Testing:**
**1. Focus and Verification:**
- **Functional Testing:** Focuses on verifying specific functionality or requirements of the software. For example, testing if a user's registration process successfully leads to dashboard access.
- **Non-Functional Testing:** Shifts focus beyond functionality, emphasizing aspects like performance. It measures how quickly users can complete actions.
**2. User Requirements:**
- **Functional Testing:** Ensures software aligns with specified functional requirements. For instance, testing registration through email, Facebook, or Google.
- **Non-Functional Testing:** Addresses non-functional requirements (NFRs) and user expectations. It validates performance against set criteria, like registration response time.
**3. Manuality:**
- **Functional Testing:** Can be conducted manually or automated based on the context, such as registering on a website.
- **Non-Functional Testing:** Often requires automation due to complexity, especially in load handling. Tools like LoadRunner, NeoLoad, or JMeter are vital for these tests.
**4. Types of Testing:**
- **Functional Testing:** Encompasses unit, integration, system, user acceptance, and regression testing.
- **Non-Functional Testing:** Includes load, stress, spike, volume testing, among others. These evaluate performance aspects like responsiveness, stability, and load handling.
**Conclusion:**
- Functional Testing verifies specific functionalities as per user requirements.
- Non-Functional Testing assesses performance aspects and user expectations.
- Non-Functional Testing often requires automation due to complexity.
- Both types have various testing categories under them.
