Test analysis: identifying test conditions
Test analysis is the process of looking at something that can be used to derive test information. This basis for the tests is called the test basis. [Read more…] about What is Test analysis / Test Basis? or How to identify the test conditions?
How to choose that which technique is best? This is the wrong question!
Each technique is good in its own way in finding out the certain kind of defect, and not as good for finding out the other kind of defects. For example, one of the benefits of structure-based techniques is that they can find out the defects or things in the code that aren’t supposed to be there, such as ‘Trojan horses’ or other malicious code.
However, if there are parts of the specification that are missing from the code, only specification-based techniques will find that, structure-based techniques can only test what is there. [Read more…] about How to choose that which testing technique is best?
This is closely related to decision coverage but has better sensitivity to the control flow. However, full condition coverage does not guarantee full decision coverage.
Other control-flow code-coverage measures include linear code sequence and jump (LCSAJ) coverage, multiple condition coverage (also known as condition combination coverage) and condition determination coverage (also known as multiple condition decision coverage or modified condition decision coverage, MCDC). This technique requires the coverage of all conditions that can affect or determine the decision outcome.

The statement coverage is also known as line coverage or segment coverage. The statement coverage covers only the true conditions. Through statement coverage we can identify the statements executed and where the code is not executed because of blockage.
