The invention discloses a regression test driven software version management method and system and a storage medium, and the method comprises the steps: carrying out the first-stage verification of anewly submitted source program through employing an available test case in a test program corresponding to a software source program of a previous version, and obtaining a first coverage result; According to the first coverage result, automatically generating a test case for carrying out test on the newly submitted source program; Carrying out second-stage verification on the newly submitted source program by adopting the generated test case to obtain a second coverage result; Compiling a new test case according to the second coverage result, and generating a test program of the newly submitted source program; And calculating a verification file and a version number of the test program, and generating new version software by combining the verification file and the version number of the newly submitted source program. The method can effectively solve the problems that a current SVM tool is difficult to effectively support management of test codes, and regression test information cannotbe fully utilized, so that research and development personnel are helped to improve software version management quality, and software product research and development efficiency is improved.
