Abstract: A centralized database and test coverage framework tools are provided to allow developers to conduct sophisticated test coverage analysis. When testing of application code occurs, information regarding line execution by each of the tests is stored in a database file unique to the corresponding test. The information contains details on how many times each line was executed during the corresponding test. The database files each may be stored in a unique subdirectory and may be grouped in clusters specified by a developer. The storing may include executing a general purpose data collector with a database location and a cluster name as parameters. Then, test coverage results may be displayed to a user by presenting the application code. A corresponding number of executions for any line in the application code which is clicked on by a user may be displayed. This allows for dynamic source code navigation.
