A walk-through (in software QA) is an informal meeting for evaluation or informational purposes. A walk-through is also a process at an abstract level. It's the process of inspecting software code by following paths through the code (as determined by input conditions and choices made along the way).
The purpose of code walk-throughs (in software development) is to ensure the code fits the purpose. Walk-throughs also offer opportunities to assess an individual's or team's competency.
A walk-through is also a static analysis technique in which a programmer leads participants through a segment of documentation or code, and the participants ask questions, and make comments about possible errors, violations of development standards, and other issues.
