Abstract
A method may include obtaining original source code including entities. The entities each correspond to a location in the original source code. The method may further include during an offline phase and by a computer processor, generating, from the original source code, (i) a dependency graph including nodes corresponding to the entities and (ii) a location index that maps each location in the original source code to one of the nodes, and during an online phase following the offline phase and using the dependency graph and the location index: identifying modified locations in the original source code by comparing modified source code to the original source code, obtaining, for each of the modified locations and by searching the location index, matching nodes, determining, for each of the matching nodes, impacted nodes reachable from the matching node, and identifying, using the location index, impacted entities corresponding to the impacted nodes.
