SDD

Question 1

Errors

Answer 1

Syntax - Prevents instruction from being executed
Execution - Occur while the program is running. Crash a program. (eg dividing by 0)
Logic - code executes but produces the wrong result

Question 2

Comprehensive testing

Answer 2

see Greg p 38

Question 3

Dry run

Answer 3

Form of testing that involves reading the program code and mentally ‘walking through’ it. Tester will predict what the code will produce and fix errors before the code is executed.

Question 4

Trace Table

Answer 4

Code is tested with test data. Trace table lists variables and tracks the values they store as code is executed

Question 5

Breakpoint

Answer 5

forces executing code to pause at points defined by the programmer, allowing the current values of variables to be examined

Question 6

Watchpoint

Answer 6

Stops the program from executing when a condition is met or when a variable changes value.
Both breakpoints and watchpoints may be used to check the current values stored by the program against the expected values.

Question 7

Comprehensive test plan

Answer 7

• ensures that all functional requirements of the program are tested
