Most of the lecture slides in this unit were developed by Ian Sommerville, author of Software Engineering. This textbook is now in its 9th edition (2011). Our library has more than a dozen copies of various

editions (from 1982!). http://www.comp.lancs.ac.uk/computing/resources/IanS/SE8/Presentations/i

ndex.html:

Powerpoint presentations, including all of the diagrams in the book, may be downloaded from this page. The presentations may be used by instructors teaching courses in software engineering. They have been designed for use in conjunction with the book so are not complete courses … I have no objections to people modifying them so long as you credit the source. You may also put these on your own server if this is more convenient for students.

Educational Goals (for Testing) Understand the importance of testing

Learn about some “famous failures”: Ariane, LAS, INCIS Discuss reasons why better testing might have avoided these

failures; and discuss other important factors. (“A” level) Know enough about test-driven development that you can

be useful on your first day of work as a developer or tester. “B” level questions: write a unit test, specify a test suite, ...

Know basic terms and concepts: validation testing, defect testing, unit test, component test, system test, … (“C” level)

Know how to use a simple tool for test automation JUnit – covered in tutorial
