Explaining briefly about Non-Functional System Testing..?

Here,we discussing about non-functional system testing and these types.

• Non-Functional System Testing:

          - it is a special type of testing performed to test the non-functional requirements like response time,portability,stability etc.

          - after completion of functional system testing,test engineers concentrating on Non-functionality of an application.

          - while conducting non-functional system testing,we should concentrating on expectations of customer like 

1. GUI Testing
2. Usability Testing
3. Compatibility Testing
4. Hardware Configurable Testing
5. Performance Testing
6. Inter System Testing
7. Security Testing
8. Installation Testing
9. Recovery Testing
10. Complex Testing.

1.GUI Testing:

           - In this testing,how professionally the application has been design,we need to check.By the time of conducting testing,we need to concentrating on below things:

            a.check for alignment

            b.check for the alignment of the object.

            c.check whether mandatory fields got highlighted or not.

            d.checking required fields and data type errors etc.

2.Usability Testing:

           - during this test,concentrating on application user friendliness or not.

           - it means look and feel easy to understand,short navigation comes into User friendliness.

3.Compatibility Testing:

           - during this test,testing team runs software on various platforms.here platforms means operating systems.

           - other system software compatibility also called as portability testing.

4.Hardware Configuration Testing:

           - testing team runs software with different technology and hardware devices.

           Ex: different types of input devices,output devices and supporting with different network's etc.

5.Inter System Testing:

           - test team need to check one system sharing resources with another system or not OR checking inter connection between 2 software's i.e called Inter System Testing (or) End to end Testing.

6.Performance Testing:

           - it means speed in processing to find a software performance.we can contact with below subsets..

        a. Load testing: the execution of software under customer expected configuration or customer expected load to estimate speed in processing is called Load Testing.

        b.Stress Testing: the execution of the software under customer expected configuration and more than customer expected load is called Stress Testing.

        c.Spike Testing:  the execution of the software under customer expected configuration and more than customer expected load,but suddenly to estimate reliability is called Spike Testing.

        d.Endurance Testing:  the execution of the software under customer expected configuration and more than customer expected load continuously to estimate durability(working long time) is called Endurance Testing.
7.Recovery Testing:
           - it is done to check how quick and improved the system can recuperate after it has getting any type of damage or hardware malfunction etc.
           - it is compulsory breakdown of the application in an assortment of conduct to validate that revival is appropriately worked.
