Software Testing: Testing Across the Entire Software Development Life Cycle
Introduction

| Software Testing: Testing Across the Entire Software Development Life Cycle |
An informal survey of twenty-one U.S. universities by the authors found that nineteen were without any software testing courses. When talking with the faculty responsible for the software testing courses in three of the universities, we learned that the largest single impediment to creating a software testing course was the absence of a good textbook. We were told that the current selection of textbooks necessitated a combination of three or four to cover many of the topics, with some topics not even covered at all. This situation leaves much of the material coverage to the professor. If he or she does not have a background in software testing, the textbooks leave gaps that is hard to fill.
Whereas this situation is disconcerting, universities and businesses in Europe and Asia seem to value testing expertise more than in the US. Instead of only three of twenty-one universities delivering testing education as in the US, the ratio in Europe is more like seven out of ten. The reason for this discrepancy is because academic and business cultures that already value software testing do not need to be sold on the value of a comprehensive, basic textbook on the subject.
