Types of Review

-
A single document may be the subject of more than one review. If more than one type of review is used, the  order may vary.  It is  apparent that none of the following types of review is the 'winner', but the different types serve different purposes at different stages in the life cycle of a document. The main review types:  Walkthrough Technical Review Inspection Walkthrough A walkthrough is characterized by the author of the document under review guiding the participants through  the document and his or her thought processes , to achieve a common understanding and to gather feedback. This is especially useful if people from outside the software discipline are present, who are not used to, or  cannot easily understand software development documents.  The content of the document is explained step by  step by the author, to reach consensus on changes or to gather information.  Within a walkthrough the author does mos...

Structure Based or Whitebox Testing Techniques

Using structure-based techniques to measure coverage and design tests Structure-based techniques serve two purposes:  test coverage measurement structural test case  design.  They are often used first to assess the amount of testing performed by tests derived from  specification-based techniques, i.e. to assess coverage. They are then used to design additional tests with  the aim of increasing the test coverage. Structure-based test design techniques are a good way of generating additional test cases that are  different from existing tests. They can help ensure more breadth of testing, in the sense that test cases  that achieve 100% coverage in any measure will be exercising all parts of the software from the point of  view of the items being covered. What is test coverage? Test coverage measures in some specific way the amount of testing performed by a set of tests . Wherever we can  count things and can tell whether o...

Phases of Formal Review

Phases of a formal review In contrast to informal reviews, formal reviews follow a formal process.  A typical formal review process consists of six main steps: Planning Kick-off Preparation Review meeting Rework Follow-up Planning The review process for a particular review  begins with a 'request for review'   by the author to the moderator (or inspection leader).  A moderator is often assigned to take care of the scheduling (dates, time, place and invitation) of the review. On a project level, the project planning needs to allow time for review and rework activities , thus providing engineers with time to thoroughly participate in reviews. For more formal reviews ,e.g. inspections, the moderator always performs an entry check and defines at this stage formal exit criteria. The entry check is carried out to ensure that the reviewers' time is not wasted on a document that is not ready for review.  ...
