Types of Black Box Testing

1. Functional Testing
2. Non-Functional Testing

1. Functional Testing

Functional Testing is a type of Software Testing in which the system is tested against the functional requirements and specifications. Functional testing ensures that the requirements or specifications are properly satisfied by the application. This type of testing is particularly concerned with the result of processing. It focuses on the simulation of actual system usage but does not develop any system structure assumptions. The article focuses on discussing function testing.

Benefits of Functional Testing

• Bug-free product: Functional testing ensures the delivery of a bug-free and high-quality product.
• Customer satisfaction: It ensures that all requirements are met and ensures that the customer is satisfied.
• Testing focused on specifications: Functional testing is focused on specifications as per customer usage.
• Proper working of application: This ensures that the application works as expected and ensures proper working of all the functionality of the application.
• Improves quality of the product: Functional testing ensures the security and safety of the product and improves the quality of the product.

2. Non-Functional Testing

Non-functional Testing is a type of Software Testing that is performed to verify the non-functional requirements of the application. It verifies whether the behavior of the system is as per the requirement or not. It tests all the aspects that are not tested in functional testing. Non-functional testing is a software testing technique that checks the non-functional attributes of the system. Non-functional testing is defined as a type of software testing to check non-functional aspects of a software application. It is designed to test the readiness of a system as per nonfunctional parameters which are never addressed by functional testing. Non-functional testing is as important as functional testing. 

Benefits of Non-functional Testing

• Improved performance: Non-functional testing checks the performance of the system and determines the performance bottlenecks that can affect the performance.
• Less time-consuming: Non-functional testing is overall less time-consuming than the other testing process.
• Improves user experience: Non-functional testing like Usability testing checks how easily usable and user-friendly the software is for the users. Thus, focus on improving the overall user experience for the application.
• More secure product: As non-functional testing specifically includes security testing that checks the security bottlenecks of the application and how secure is the application against attacks from internal and external sources.

Welcome to the world of software testing, which ensures the quality and reliability of software applications. Understanding the various types of software testing is essential for developers and quality assurance professionals alike.

In this guide, we’ll explore the fundamental categories of software testing, from unit testing to security testing, helping you navigate and ensuring your software will meet the highest standards of performance and functionality.
