TESTING

                                                               TESTING

Static analyses used to investigate the structural properties of source code. Dynamic list cases are used to investigate  the behavior of source code  by executing. The program on the text data.

UNIT TESTING

                     

                      Unit testing comprises the set  of test performed  by an individual Programmer prior to integration of the unit into a larger system

• Functional test
• Performance test

FUNCTIONAL TEST

  

                  Cases involve  exercising the code  with nominal input value for the Expected labs are known as  well as boundary  values .

                       In my project functional test  is done by testing in forms of contact  property ,and main form of  login form  and options .vb.

PERFORMANCE TEST

                Determines the amount of execution  time spent  in various part of the

Unit , program through input , response time, and device utilization by the program unit.

                    In my project  performance test is done by testing in forms of contacting which used to enter login form to signing our id.

INTEGRATION TESTING

                    

                Integration test the modules are combined  and checked , a  subsystem  consists of  several modules that communicated  with each other through  well defined  Interfaces  both control ,and data inter face must be tested . in my project  integration testing is done by testing in forms  of all in  our forms.

MAINTENANCE

Provision must  be made for environmental  change ,which may affect either  the  computer  or  other parts of  computer based system. such activity   is normally  called “MAINTENANCE”. It includes both the improvement  of system function and  the correction  of facilities, which arise during the operation of a system.

Maintenance  activity may require the containing involvement of a large proportion  of

Computer  department resources . For  computer installation which have already  developed  the basic application for the organization the main task may to adopt

Existing system in a changing environment  perhaps  a better  team to describe  this activity  is  “system evolution”.All system  are dynamic and subject to constantly

Changing requirements .Efforts must be devoted  to adopting  them and design should be

Flexibly specified.So that changes can be easily implement.

MOST CHANGES ARISE IN TWO WAYS

• As part of the normal running  of the system when error are found. User ask for improvement  of  external requirement changes .

• As a result of specific investigation and review  of the system performance.
