Static analysis in selective software regression testing

A device comprising:

• a processor to:
• store one or more changes to source code that includes functions and global data elements of a software project;
• perform a static analysis of the source code to determine functions in the source code and global data elements in the source code that correspond to one or more changed functions of the source code,
• the processor, when the performing the static analysis, being further to:
• analyze a set of the one or more changed functions to determine a respective impacted scope of the one or more changed functions in the set of the one or more changed functions;
• determine, based on analyzing the set of the one or more changed functions, at least one of the functions that is called by a respective changed function of the one or more changed functions;
• mark one or more global data elements that correspond to the respective impacted scope of the one or more changed functions in the set of the one or more changed functions;
• and
• determine whether one or more other functions read data from the marked one or more global data elements,
• the one or more other functions being different than the functions, and
• the one or more other functions not being directly called by the functions;
• and
• execute a test of the software project using a set of test units determined based on the static analysis of the source code.

A method comprising:

• storing, by a device, one or more changes to source code that defines functions and global data elements of a software project, the source code implementing a uniform naming scheme for the global data elements;
• performing, by the device, a static analysis of the source code to determine which global data elements in the source code correspond to one or more changed functions of the source code, performing the static analysis including:
• determining an impacted scope for a set of the one or more changed functions based on one or more functions that are called by the one or more changed functions and one or more functions that call the one or more changed functions and receive a return value from the one or more changed functions;
• marking one or more global data elements that correspond to the impacted scope of the one or more changed functions in the set of the one or more changed functions;
• and
• determining whether one or more other functions read data from the marked one or more global data elements,
• the one or more other functions being different than the functions, and
• the one or more other functions not being directly called by the functions;
• and
• performing, by the device and based on the static analysis, a task.

A non-transitory computer-readable medium containing instruction, the instructions comprising:

• one or more instructions which, when executed by at least one processor, cause the at least one processor to:
• store one or more changes to source code that includes functions and global data elements of a software project;
• perform a static analysis of the source code to determine functions in the source code and global data elements in the source code that correspond to one or more changed functions of the source code, the one or more instructions to perform the static analysis including one or more instructions to:
• analyze a set of the one or more changed functions to determine a respective impacted scope of the one or more changed functions in the set of the one or more changed functions;
• determine, based on analyzing the set of the one or more changed functions, at least one of the functions that is called by a respective changed function of the one or more changed functions;
• mark one or more global data elements that correspond to the respective impacted scope of the one or more changed functions in the set of the one or more changed functions;
• and
• determine whether one or more other functions read data from the marked one or more global data elements,
• the one or more other functions being different than the functions, and
• the one or more other functions not being directly called by the functions;
• and
• execute a regression test of the software project using a set of test units determined based on the static analysis of the source code.
