A walk-through test is a process used to assess the trustworthiness of an entity's accounting system during an audit. A walk-through test follows a transaction from its conception to its final disposal via the accounting system.
A walkthrough is a one-time method of ensuring quality. Walkthroughs are informal but purposeful gatherings. An inspection is a systematic, rigorous, in-depth group assessment aiming to discover problems as close to their source as possible.
Code inspection is a sort of static testing that involves reading software code and looking for errors. It reduces the fault multiplication ratio and prevents subsequent stage error detection by simplifying the entire first error detection process.
