In this chapter we will look at testing as part of overall software development. Determining if more tests are needed or if the specified exit criteria need amending.

This may sound strange, but remember that failures often begin with a human error, namely a mistake in a document such as a specification. Note that when the developer removes the defect, this activity is called debugging, which is not a testing activity. Keep the focus on delivering foundatoon quality product. Units are also called programs, modules or components. In software development, work-products are generally created in a series of defined stages, from capturing a customer requirement, to creating the system, to delivering the system.

As its name suggests, test cases are written first, code built, tested and changed until the unit passes its tests. The authors are all experienced ISEB exam setters, markers and training providers.

However, we need to understand a little 14 Software Testing 2nd Edition: If you are using the book as a revision aid you may find the second approach more appropriate. This can be run as a meeting or simply by sending out the details to the reviewers. The control structure of a program can be fooundation in a chart.

The learning objectives can be used to check that learning or revision is adequate for each topic. No trivia or quizzes yet. The code of ethics is far reaching in its aims, and a quick review of the eight points reveals interaction with other areas of the syllabus. However, although we know that testers should be involved from the beginning, it is not always good to get testers involved in code execution at an early stage; there are advantages guid disadvantages.

The benefit of this independence is that an objective assessment of the system can be made, based on the specifications as written, and not the code. K2 Recall the common objectives of testing. We want to do this to check the thoroughness of the testing carried out on the system that has actually been built. Even then, the number of possibilities is higher.

We need to rework not just the part where the mistake was made, but each subsequent part where the error has been replicated. Reviewers identify issues or problems and inform the author either verbally or in a documented form, which might be as formal as raising a defect report or as informal as annotating the document under review.

We have recognised that it is an activity used to reduce risk and improve quality by finding defects, which is all true. However, if every test had been run, the testing would still be running now, and the ill-fated launch would never have taken place; this illustrates one of the general principles of software testing, which are explained below.
