One of the static testing methods is structural walkthrough.

In walkthroughs, a set of people look at the program code and raise questions for the author. The author explains the logic of the code and answers the questions. If the author is unable to answer some questions, he or she then takes those questions and finds their answers.

(i) Walkthroughs are the next step up in formality from peer reviews.

(ii) In a walkthrough, the programmer who wrote the code formally presents (walks through) it to a small group of five or so other programmers and testers.

(iii)The reviewers should receive copies of the software in advance of the review so they can examine it and write comments and questions that they want to ask at the review.

(iv) Having at least one senior programmer as a reviewer is very important.
