Abstract: Testing systems and methods are provided for determining domain data coverage of a test of a codebase. The testing system may include a coverage program having a setup module configured to receive user input indicative of a target domain data table to be monitored during the test. The coverage program may further include a test module configured to programmatically generate a shadow table configured to receive coverage data, and to create one or more triggers on the target domain data table. The triggers may be configured, upon firing, to make entries of coverage data in the shadow table indicating that the trigger was fired during the test. The coverage program may also include an output module configured to compare the shadow table and the target domain data table to produce a coverage result, and to display the coverage result via a graphical user interface.
