Unit testing

CPA-Quantitative-Analysis-Section-4 BLOCK RELEASE

Programmers usually perform unit testing. Programmers receive specifications from systems designers and develop programs to meet these requirements. Once they are sufficiently confident about their programs they undertake a set of formal tests. These are usually designed to:-
– Ensure that every line of the program has been executed and is working properly
– Ensure that data stored the program is accurately placed in the correct filed in the database
– Ensure that interactions with other programs are working correctly
– Ensure that error conditions are handled correctly
Unit testing is performed explicitly on the program code and structure. It is often termed white box testing because it is concerned with inspecting the internal logic of the program.
