Dr. Edward J. Moskal - August 6, 2004

Introduction

Before any system can be completely implemented on a production computer, the analysts and programmers working on the system must be able to state unequivocally that the programs work exactly as they were designed to work and that any errors or mistakes found in any of the data to be processed by the system will be handled properly. Since testing is quite unpredictable in terms of the results and, in some cases, the availability of the hardware required for testing, it is difficult to establish a day-to-day detailed testing schedule in advance. It should be possible, however, to estimate with some accuracy the time which will be required to test any given program. The most likely area for the "slipping" of deadlines in the implementation falls within the area of program and systems testing. When testing schedules are established, there should be adequate time allocated for testing...
