An intelligent test system for testing software code is provided. The intelligent system includes a profiled software component, a test executor, a database, a database updater, and a data analyzer/optimizer. The test executor creates a coverage data by using the profiled software component to execute a plurality of test cases of a test suite. The database stores the coverage data and the database updater is configured to store the coverage data into the database. The data analyzer/optimizer analyzes the coverage data contained in the database to find test cases affected by a modification to the software code. The data analyzer/optimizer also optimizes the test cases affected by the modification by selecting fewer test cases that satisfy a criteria. The test executor uses the test cases that satisfy the criteria to test the modification to the software code.
