Software development test case analyzer and optimizer

A data collection module of a test system, the data collection module comprising:

• a test suites component having a test suite including a plurality of test cases;
• a profiled software component;
• a test executor being configured to use the profiled software component to process the test cases in the test suite so as to create coverage data;
• a database configured to store the coverage data;
• and
• a database updater configured to store the coverage data into the database,
• wherein the coverage data stored in the database is used to eliminate redundant test cases.

A data processing module for use in a test system, the data processing module comprising:

• a database component storing coverage data;
• a source code controller system configured to provide modified information, the modified information defining a modification to source code;
• a data analyzer/optimizer configured to analyze the coverage data using the modified information so as to find test cases affected by the modified information, the data analyzer/optimizer further configured to create a precision test list that includes the test cases satisfying a criteria;
• and
• a test executor configured to use the test cases satisfying the criteria to test the modification to the source code.

A method for testing computer software under development, the method comprising:

• using instrumented code to execute test cases in a test suite so as to create coverage data;
• storing the coverage data in a database;
• obtaining modification information to the source code of the computer software under development;
• analyzing the coverage data in the database so as to find test cases affected by a particular modification to the source code;
• creating a dependency test list of all test cases affected by the particular modification to the source code;
• optimizing the test cases in the dependency test list by selecting the test cases satisfying a criteria;
• and
• executing the source code using selected test cases satisfying the criteria.
