Path testing is a structural testing method that focuses on executing all paths through the code or algorithm based on its structure rather than specifications. It involves converting the program into a control flow graph by representing the code as nodes, regions, and edges to show the flow of execution. This allows testers to ensure all statements are executed by following each path in the graph from start to finish.

2. What is Path Testing?
Path Testing is a structural testing method based on
the source code or algorithm and NOT based on the
specifications. It can be applied at different levels of
granularity.
Path Testing is a structural method for unit testing its
called to insure that all statements is executed
