Code Coverage Basic Metrics
Statement Overlay Statement Coverage (line coverage):
statements needs to be tested in 1024 paths. If we add an if statement, 2048 paths need to be tested. Secondly, due to the relationship between data, some paths cannot be tested, such:
if(success) statement1;statement2;if(success) statement3;
This Code contains four paths. In fact, there are only two feasible items, success = false and success = true.Other metrics of code
