2.3 Implementation & Unit Testing
After accepting the system design specification, the work
is divided into modules/units and actual coding will
commence. The system is first developed in small programs
called units. Each unit is developed and tested for its
functionality; this is referred to as Unit Testing.Unit testing
mainly verifies if the modules/units meet their specifications.
The units that meet the specifications are then integrated in
the next phase.
In this work, the Design specification that has been identified
earlier can be broken down into 5 modules as depicted in
figure 2.
