Path coverage measures whether each of the possible paths in each function have been covered for testing. A path is a unique sequence of branches from the function entry to the exit. A very through testing is possible by Path Coverage.
Path coverage is measures by an entity called cyclomatic complexity. The cyclomatic complexity of a software program is calculated from a connected graph of the module (that shows the topology of control flow within the program):
Cyclomatic complexity (CC) = E - N + Pwhere E = the number of edges of the graphN = the number of nodes of the graphP = the number of connected components   Your Comment
