GRAPHICAL USER INTERFACE AND DEBUGGER SYSTEM FOR SELECTING AND TESTING ALTERATIONS TO SOURCE CODE FOR SOFTWARE APPLICATIONS

Testing for software applications can be implemented according to some aspects described herein. For example, a system can receive override data, including a location of a logical statement in source code and an override command, that is associated with a software application. The system can generate debugging data based on the override data, the debugging data including a breakpoint associated with the location and a debugger command corresponding to the override command. The system can then provide the debugging data as input to debugging software, the debugging software being configured to monitor execution of the software application during a software test. The debugging software can determine that the breakpoint has been reached and responsively execute the debugger command for testing a target portion of source code for the software application.
