Conclusion the software development method that has been used to develop is the system development life cycle (sdlc) waterfall model it consists of a series of seven steps conceptualization, requirements cost/benefit analysis, requirement analysis, system analysis and design, code generation, system testing and lastly system maintenance. The essence of waterfall software development is that complex software systems can be built in a sequential, phase-wise manner where all of the requirements are gathered at the beginning, all of the design is completed next, and finally the master design is implemented into production. Software testing is integral part of the software development life cycle (sdlc) and identifying the accuracy, correctness and efficient of the software (tauhida p, scott t, george g, 2007) the objective of software testing is to find the defects of the software and provide the reliable quality for customers.
