Stepping and application state viewing between points

At least one computer-readable storage medium that is not a signal or carrier wave per se having computer-executable instructions that, when executed by a computer, cause the computer to perform a method comprising:

• setting, via a debugger, a start breakpoint and an end breakpoint in a portion of code;
• executing the portion of code from at least the start breakpoint;
• logging, starting at the start breakpoint set in the executing portion of code, values of variables in scope of the portion of code whether or not the values are changed as a result of the executing;
• breaking the execution at the end breakpoint set in the executing portion of code resulting in an executed and logged portion of code from the start breakpoint up to the end breakpoint;
• and
• providing, in response to the breaking, the stepping and state viewing in the form of a bi-directional playback feature configured to play back a path of the executed and logged portion of code, and further configured to show to a user via the bi-directional playback feature the logged values of the variables at each point of execution of the executed and logged portion of code.

A system comprising:

• a breakpoint feature configured for setting, via a debugger, a start breakpoint and an end breakpoint in a portion of code;
• a computing device configured for executing the portion of code from at least the start breakpoint;
• a logging feature configured for logging, starting at the start breakpoint set in the executing portion of code, values of variables in scope of the portion of code whether or not the values are changed as a result of the executing;
• the breakpoint feature further configured for breaking the execution at the end breakpoint set in the executing portion of code resulting in an executed and logged portion of code from the start breakpoint up to the end breakpoint;
• and
• a bi-directional playback feature configured to operate on the computing device and configured to playback, in response to the breaking, a path of the executed and logged portion of code, and further configured to show to a user the logged values of the variables at each point of execution of the executed and logged portion of code.
