System Testing And Integration

Software Testing - This defines the test requirement, which the software should meet and it is progressively integrated into complete package. The process of test plan is concerned with providing that a package produces correct and expected result for all possible input data. For this software testing, we have three basic testing that should be adopted namely:

module testing
Integrated testing and
System testing

Module Testing

In this design, we have many modules which when triggered up at certain events perform a specific function. So, module testing involves testing of each of the modules in software to verify that they meet their respective objective module testing were carried out ensure that information properly flows into and out of the program module under test.

The Integration Test

So far, the various modules have been tested and each proved efficiency as an entity (i.e. module). Though sometimes, the modules can perform their respective functions but when put together, they can function together. So this test therefore checks that when the modules are integrated their can combine to perform their respective functions. Hence, integration testing was done to entire program structure to uncover errors associated with interfacing. These errors were debugged to produce desired result. The essence of integration testing is to ascertain that these modules do not lose their efficiency and reliability. The integration involved the main form which serves as coordinator and driver for other modules.

System Testing

Before bringing and data processing system into use. It is of vital importance that the system is both comprehensive within its intended limits and fully correct. So, each routine must have been written according to specification and tested to complete satisfaction. Also bugs must have been removed completely and the program run produced exactly what is required of it.

Test Data

The test data enables one to check the performance of the software while test running this software. Data obtained from two sources were used.

1 Imaginary data

2 Real data

Imaginary data were used to carry out the test that was basically meant to check for errors and also to make sure that the system produces expected data specified. This is called verification testing.

Real data were obtained from direct source and used to carry out the test.
