SYSTEM TESTING
SYSTEM TESTING
• SYSTEM TESTING is a level of software
Testing where a complete and integrated
Software is tested.The purpose of this is to
evaluate the system’s compliance with the
specified requirements.
Method Followed, When is it performed?
• Usually , Black box testing method is used.
When performed:
System Testing is the third level of testing
performed after integration testing.
Who performs it ?
Normally, independent Testers perform System
Testing.
Four categories of Testing,
• Usability
• Functionality
• Performance
• Security
Black Box Testing
• It cannot be the alternative for White box.
• It checks the behaviour,hence also known as
behavioural testing.
• Foruses on functional requirements.
• Helps in deriving a set of input conditions.
• It is applied in the final stage of testing.

Types of System testing :
• Functional
• Non-Functional
Functional Testing
• Functionality Testing:
Testing the behaviour of the application.
• Sanity Testing:
Testing the minor functionality of the
application.
• Regression Testing:
Testing the whole application to check
whether new requirement changes affects
previous functionality.
Non-Functional Testing
• Usability Testing:
User friendly
look and feel
ease of Use
Context sensitiveness
Performance Testing:
1.Load Testing: Application Loading Time
2.Stress Testing: Estimates the peak load
3.Data/Volume Testing: Test to find the
Maximum limit of data/volume of your
Application.
Security Testing:
Protecting from unauthorized access.
