Abstract: Disclosed is an automatic parsing and path analysis method for a unit test code structure. The method comprises: acquiring compiled byte codes according to a language of a test program; traversing the complied byte codes, making instrumentation codes respectively in front of important statements, and acquiring node information and a small-segment path set (SSPS); analyzing the SSPS, replacing a part therein comprising nesting to obtain a SSPS excluding nesting as a basis, initializing a path table among the nodes, updating the path table by utilizing a depth-first algorithm, and obtaining path sets according to the path table; if all the path sets have been updated, returning to continuously update the path table; and outputting the acquired path sets and a program flowchart CFG obtained by analysis. The method above is capable of acquiring the path sets efficiently, thereby improving the capability of processing path analysis in actual software unit test.
