Debugging - Techniques

Techniques

• Print (or tracing) debugging is the act of watching (live or recorded) trace statements, or print statements, that indicate the flow of execution of a process. This is sometimes called printf debugging, due to the use of the printf statement in C.

• Remote debugging is the process of debugging a program running on a system different than the debugger. To start remote debugging, debugger connects to a remote system over a network. Once connected, debugger can control the execution of the program on the remote system and retrieve information about its state.

• Post-mortem debugging is debugging of the program after it has already crashed. Related techniques often include various tracing techniques (for example,) and/or analysis of memory dump (or core dump) of the crashed process. The dump of the process could be obtained automatically by the system (for example, when process has terminated due to an unhandled exception), or by a programmer-inserted instruction, or manually by the interactive user.

• Delta Debugging - technique of automating test case simplification.

• Saff Squeeze - technique of isolating failure within the test using progressive inlining of parts of the failing test.
