Test and Review
Generally, two kinds of software testing procedures can be differentiated. While dynamic tests are realized during the program runtime, statistical testing procedures are characterized by the fact that the software is not running during these tests.
Reviews offer the possibility to execute already very early on in the development phase quality protection measures. With the help of a complete review, about 60-90 % of all malfunctions are discovered. Participants of a review are at least the author of the program, an expert, a recorder and a moderator. A standardized checklist is frequently used in this connection. The "walkthrough" is a variant of the review with less formalistic expenditure and fewer participants.
