TAILIEUCHUNG - Lecture Software construction - Lecture 19: Software testing (part 2)

The goals of this chapter are: What are your initial questions? Should I analyse the specification carefully, as in black-box testing, to discover “what the code should be doing”? Does white-box testing have an advantage, over black-box testing, in testing “what the program is not intended to do”? Should I carefully test interfaces, exceptions, or error returns, or should I concentrate on confirming the correctness of functional “internal” behaviour? | Software Construction Lecture 19 Software Testing-2 Learning Goals for Today D3 2 Develop a test suite for some code after looking at it. (White-box testing.) What are your initial questions? (Have you written some already?) Should I analyse the specification carefully, as in black-box testing, to discover “what the code should be doing”? Does white-box testing have an advantage, over black-box testing, in testing “what the program is not intended to do”? Should I carefully test interfaces, exceptions, or error returns, or should I concentrate on confirming the correctness of functional “internal” behaviour? Start to develop your own “principled approach” to software testing. White-Box Testing D3 3 “This strategy derives test data from an examination of the program’s logic “(and often, unfortunately, at the neglect of the specification).” What is the overall strategy or “gold standard” for white-box testing? “Causing every statement in the program to execute at least once”? No this
