Code review (sometimes referred to as peer review) is a software quality assurance activity in which one or more people examine the source code of a computer program, either after implementation or during the development process. The persons performing the checking, excluding the author, are called "reviewers".
The software development process is a typical application of Fagan inspection. As the costs to remedy a defect are up to 10 to 100 times less in the early operations compared to fixing a defect in the maintenance phase, [1] it is essential to find defects as close to the point of insertion as possible.
A code review can be done as a special kind of inspection in which the team examines a sample of code and fixes any defects in it. In a code review, a defect is a block of code which does not properly implement its requirements, which does not function as the programmer intended, or which is not incorrect but could be improved (for example, it ...
Wikipedia's code review process is a way to receive feedback from other editors about new or proposed changes to a user script or Gadget. Such changes would usually be proposed by the script's maintainer, unless they are inactive.
When performed as part of each Software development process activity, peer reviews identify problems that can be fixed early in the lifecycle. [1] That is to say, a peer review that identifies a requirements problem during the Requirements analysis activity is cheaper and easier to fix than during the Software architecture or Software testing ...
Code review is systematic examination (often as peer review) of computer source code. Pair programming is a type of code review where two persons develop code together at the same workstation. Inspection is a very formal type of peer review where the reviewers are following a well-defined process to find defects.
A review program can also provide an automated or a programmer-assisted way to correct the issues found. This is a component for mastering easily software. This is contributing to the Software Intelligence practice. This process is usually called "linting" since one of the first tools for static code analysis was called Lint. Some static code ...
The term is usually applied to analysis performed by an automated tool, with human analysis typically being called "program understanding", program comprehension, or code review. In the last of these, software inspection and software walkthroughs are also used.
