A coverage monitor subsystem receives an electronic message from a project data object over a communication network. The project data object includes decision code modules that have rules with a corresponding test status variable. The test status variable indicates whether the rule has been tested. The coverage monitor subsystem generates a test status identifier. The test status identifier indicates the decision code modules as tested decision code modules when all of the rules for the corresponding decision code modules have been tested. The coverage monitor subsystem transmits test status data to a reporting subsystem. The test status data includes a first identifier identifying the tested decision code modules and a second identifier identifying the decision code modules that are not tested. The reporting subsystem displays, at a computer display, a graphical representation based on the first identifier and the second identifier.
