Non-functional Testing

 

                                                   Non-functional Testing

Non-functional testing focuses on aspects of a software system that are not related to its specific functionality but rather its overall performance, reliability, and user experience. Here are some types of non-functional testing explained in simple terms with examples:

1. Performance Testing:

   • Purpose: Evaluates how well the software performs under various conditions, such as load, stress, and scalability.
   • Example: Testing a website to see how quickly it loads pages when multiple users access it simultaneously.
   • 
     

2. Usability Testing:

   • Purpose: Assesses how user-friendly and intuitive the software interface is for its intended users.
   • Example: Having users interact with a mobile app to see if they can easily navigate through different screens and perform tasks without confusion.
   • 
     

3. Reliability Testing:

   • Purpose: Checks how dependable the software is in terms of its ability to perform consistently and accurately over time.
   • Example: Running a software application continuously for an extended period to ensure it doesn't crash or produce unexpected errors.
   • 
     

4. Security Testing:

   • Purpose: Identifies vulnerabilities and weaknesses in the software's security measures to protect against unauthorized access, data breaches, and cyber-attacks.
   • 
     
   • Example: Testing a web application to uncover any potential security flaws, such as SQL injection or cross-site scripting vulnerabilities.
   • 
     

5. Compatibility Testing:

   • Purpose: Ensures that the software functions correctly across different devices, operating systems, browsers, and network environments.
   • Example: Testing a mobile app on various smartphones and tablets to ensure it works seamlessly on different screen sizes and hardware configurations.
   • 
     

6. Scalability Testing:

   • Purpose: Measures the software's ability to handle an increasing amount of workload or data without compromising performance or functionality.
   • Example: Testing an e-commerce website to see how it handles a sudden surge in traffic during peak shopping seasons without slowing down or crashing.

These types of non-functional testing help ensure that the software not only works as intended but also meets the broader requirements related to performance, usability, reliability, security, compatibility, and scalability.
