Types of Non-Functional Testing
Given below are the various types of Non-Functional Testing.
#1) Load Testing: An application which is expected to handle a particular workload is tested for its response time in a real environment depicting a particular workload. It is tested for its ability to function correctly in a stipulated time and is able to handle the load.
#2) Stress Testing: In Stress testing, the application is stressed with an extra workload to check if it works efficiently and is able to handle the stress as per the requirement.
Example: Consider a website which is tested to check its behavior when the user accesses is at its peak. There could be a situation where the workload crosses beyond the specification. In this case, the website may fail, slow down or even crash.
Stress testing is to check these situations using automation tools to create a real-time situation of workload and find the defects.
#3) Volume Testing: Under Volume testing the application’s ability to handle data in the volume is tested by providing a real-time environment. The application is tested for its correctness and reliability under adverse conditions.
#4) Endurance Testing: In Endurance testing the durability of the software is tested with a repeated and consistent flow of load in a scalable pattern. It checks the endurance power of the software when loaded with a consistent workload.
All these testing types are used to make the software work bug-free and crash free under any real time situation by addressing the issues and finding solutions accordingly for a quality product.
In this type of testing the User Interface is tested for its ease of use and see how user-friendly it is.
Security Testing is to check how secure the software is regarding the data over the network from malicious attack. The key areas to be tested in this testing include authorization, authentication of users and their access to the data based on the roles such as admin, moderator, composer, and user level.
Thus after knowing the definitions, one can get a clear idea of the difference between functional and non-functional testing.
