Systems that work heavily on coding applications are often overwrought with lines and paragraphs of syntactical and contextual language that can be tough to understand to the average pair of eyes.
Even more cumbersome and tiring is the process of debugging and looking for errors in the source code whenever some pesky errors arrive, or the results don't match the expected output.
As technology undergoes an upheaval in the techniques and ideas used to uphold the tenants of advancement, so do the methods that are used to ensure that there is no room for errors and other discrepancies.
The code review process also referred to as peer review, stands out as a tried and tested method in a large palette of
applications to allow for the systematic examination of software source code. It's conducted to find bugs and improve the overall quality of the software. The Roles Found In Code Review Process
There are at least two roles that are always present in a code review:-
The author, who is responsible for creating the code being reviewed The reviewer, who is the person responsible for examining the code and reporting the results to the author.
The code review process can occur over a large network of programmers and debuggers or can be a shared task among a small group of developers. Often there is a particular platform or methodology(such as
Agile) that runs in the background to ensure that the process yields reasonable results. Examples Of Lightweight Techniques Over-the-shoulder One developer looks over the author's shoulder as the latter runs through the code and suggests changes to be made. This method is more appropriate when dealing with short snippets, and extreme accuracy is required regarding the results. Email pass-around As the name suggests, the author or the SCM system creates a hierarchical system and emails code to reviewers. Pair Programming Two authors develop the source code together at the same workstation and reverse engineer the results with the assumption that they would arrive at the same base kernels. Tool-assisted Obvious to the name, this means that authors and reviewers use specialised tools designed for peer code review.
Why The Code Review Process Matters
It’s a rather common question to come across. Why bother reviewing code? The benefits or the goals of the code review process well range in the following reasons:-
According to the
single responsibility principle (SRS), do not place multiple responsibilities into a single class or function and instead, refactor them into separate classes and functions.
Use the open-closed principle when adding new functionality or when existing code should not be modified. New functionality should be overwritten in new classes and functions.
Avoid lengthy interfaces and split them into smaller components based on the functionality. The interface should not contain any dependencies that are not a part of the expected functionality.
As a rule, do not hardcode the dependencies but inject them instead.
The first step while assessing the code quality can be a hassle of great proportions that can be best dealt with using a static code analysis tool.
Use plugins such as SonarQube, NDepend, TFS and FxCop to get an in-depth analysis of the code. Resharper is another great plugin when dabbling with Visual studio.
To track the code review comments, conclude using tools like Crucible, Bitbucket and TFS code and complete review process.
What might seem like the trickiest and often the most laborious procedure of application development has to be cleaned and filtered for being usable. As such, always remember the importance of keeping the code reviewed and why it has to be done. Treat it not like a crucial step but an indispensable one.
