4. Choosing the Right Code Coverage Metric:
Before instituting a test monitoring strategy, it is necessary to define what should be tracked and analyzed. It is thus necessary to choose the most relevant metric for code coverage from the existing metrics such as Function coverage, line coverage, statement coverage, decision coverage, etc. A general rule is to say that a single issue should be monitored by a single measurement, simply to make the analysis easier. Following all metric values makes the results difficult to interpret.
