Code coverage rate determination method and system

A code coverage rate determination system, comprising:

• at least one processor configured to
• retrieve source code of a program;
• prior to executing the program, determine a theoretical number of log file output points included in the source code and location information of the log file output points included in the source code, wherein each log file output point corresponds to at least one line of code, and each log file output point outputs at least one log file when executed;
• execute the program;
• retrieve log files actually outputted during the execution of the program, wherein each log file comprises location information of its corresponding log file output point;
• determine an actual number of log file output points of the actually outputted log files based on the location information of the corresponding log file output points recorded in each log file, the determining comprising:
• a) analyze content of the actually outputted log files to obtain the location information of the corresponding log file output points, wherein the actually outputted log files were generated during the same execution of the program;
• merge log files containing the same location information into one merged log file in the event that more than one log file contains the same location information, wherein a merged log file corresponds to a log file output point;
• and
• count a final number of the log file output points of the actually outputted log files based on a total number of merged log files;
• or
• b) count an actual number of log files outputted for each log file output point based on the location information of the corresponding each log file output point contained in each log file, wherein the actually outputted log files were generated during the same execution of the program;
• for each log file output point where the actual number of log files outputted is greater than 1, subtract a value 1 from the actual number of log files outputted for each log file output point to obtain a number of repetitions outputted by each log file output point;
• and
• subtract the number of repetitions outputted by each log file output point from a total number of actually outputted log files to obtain a final number of log file output points of the actually outputted log files;
• and
• determine a code coverage rate of the program based on the theoretical number of log file output points included in the source code and the final number of the log file output points of the actually outputted log files;
• and
• a memory coupled to the at least one processor and configured to provide the at least one processor with instructions.

A computer program for determining a code coverage rate, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

• retrieving source code of a program;
• prior to executing the program, determining a theoretical number of log file output points included in the source code and location information of the log file output points included in the source code, wherein each log file output point corresponds to at least one line of code, and each log file output point outputs at least one log file when executed;
• executing the program;
• retrieving log files actually outputted during the execution of the program, wherein each log file comprises location information of its corresponding log file output point;
• determining an actual number of log file output points of the actually outputted log files based on the location information of the corresponding log file output points recorded in each log file, the determining comprising:
• a) analyzing content of the actually outputted log files to obtain the location information of the corresponding log file output points, wherein the actually outputted log files were generated during the same execution of the program;
• merging log files containing the same location information into one merged log file in the event that more than one log file contains the same location information, wherein a merged log file corresponds to a log file output point;
• and
• counting a final number of the log file output points of the actually outputted log files based on a total number of merged log files;
• or
• b) counting an actual number of log files outputted for each log file output point based on the location information of the corresponding each log file output point contained in each log file, wherein the actually outputted log files were generated during the same execution of the program;
• for each log file output point where the actual number of log files outputted is greater than 1, subtracting a value 1 from the actual number of log files outputted for each log file output point to obtain a number of repetitions outputted by each log file output point;
• and
• subtracting the number of repetitions outputted by each log file output point from a total number of actually outputted log files to obtain a final number of log file output points of the actually outputted log files;
• and
• determining a code coverage rate of the program based on the theoretical number of log file output points included in the source code and the final number of the log file output points of the actually outputted log files.
