This measure reports whether each of the possible paths in each function have been followed. A path is a unique sequence of branches from the function entry to the exit.Path coverage has the advantage of requiring very thorough testing. Path coverage has two severe disadvantages. The first is that the number of paths is exponential to the number of branches. For example, a function containing 10 if-statements has 1024 paths to test. Adding just one more if-statement doubles the count to 2048. The second disadvantage is that many paths are impossible to exercise due to relationships of data. For example, consider the following C/C++ code fragment:if (success) statement1;statement2;if (success) statement3;Path coverage considers this fragment to contain 4 paths. In fact, only two are feasible: success=false and success=true.

RE: what is path coverage?. How many path coverage are...
this is cyclometric complexity problem for path coverage one wants to find out the number of paths involved in a program. no. of decision+1= path coverage
RE: what is path coverage?. How many path coverage are...
Path coverage is nothing but the number of paths from start to end of an application. Possible path coverages can be calculadet by Cyclometic complexity = V- E+2
RE: what is path coverage?. How many path coverage are possible?.
A path represents the flow of execution from the start of a method to its exit.
The cyclomatic complexity of a software module is calculated from a connected graph of the module (that shows the topology of control flow within the program):
