Automatic regression testing based on cyclomatic complexity

A computer program product for automating regression testing, the computer program product comprising a computer readable storage medium having program code embodied therewith, the program code readable and executable by a processor to perform a method comprising:

• identifying, by a processor, a base code change in a software program;
• receiving, by the processor, a string of binary data that represents a cyclomatic complexity of the base code change;
• mapping, by the processor, the base code change to different software test routines, wherein the different software test routines have been predetermined to test changes to the software program;
• and
• executing, by the processor, a quantity of the different software test routines on the base code change to automatically perform regression testing on the software program, wherein the quantity of the different software test routines that are executed on the base code change is determined by the cyclomatic complexity of the base code change.

A computer system comprising:

• a processor, a computer readable memory, and a computer readable storage medium;
• first program instructions to identify a base code change in a software program;
• second program instructions to receive a string of binary data that represents a cyclomatic complexity of the base code change;
• third program instructions to map the base code change to different software test routines, wherein the different software test routines have been predetermined to test changes to the software program;
• and
• fourth program instructions to execute a quantity of the different software test routines on the base code change to automatically perform regression testing on the software program, wherein the quantity of the different software test routines that are executed on the base code change is determined by the cyclomatic complexity of the base code change;
• and wherein the first, second, third, and fourth program instructions are stored on the computer readable storage medium for execution by the processor via the computer readable memory.
