developers. This provides the product for real use and detects errors which may not have been 
anticipated by the system developers.
Unit Testing: 
Each module is considered independently. it focuses on each unit of software as implemented 
in the source code. it is white box testing. 
Integration Testing: 
Integration testing aims at constructing the program structure while at the same constructing 
tests to uncover errors associated with interfacing the modules. modules are integrated by using 
the top down approach. 
Validation Testing: 
Validation testing was performed to ensure that all the functional and performance requirements 
are met. 
System Testing: 
It is executing programs to check logical changes made in it with intention of finding errors. a 
system is tested for online response, volume of transaction, recovery from failure etc. System 
testing is done to ensure that the system satisfies all the user requirements.

Implementation and Software Specification Testings 
Detailed Design of Implementation 
This phase of the systems development life cycle refines hardware and software specifications, 
establishes programming plans, trains users and implements extensive testing procedures, to 
evaluate design and operating specifications and/or provide the basis for further modification. 
Technical Design 
This activity builds upon specifications produced during new system design, adding detailed 
technical specifications and documentation. 
Test Specifications and Planning 
This activity prepares detailed test specifications for individual modules and programs, job 
streams, subsystems, and for the system as a whole.
