Code review before or after testing
In a software development lifecycle, the development and testing teams carry out a lot of internal processes to ensure the best possible quality of the software. Software development teams widely practice and adopt Code Review benefits. Show The process of code review before or after QA is often ignored in the software development process to prefer traditional testing methodologies. But, ignoring the process of code review can have huge repercussions that could take more time and resources to fix at a later stage. This article helps you understand QA Code Review, why it is necessary, the difference between code review and testing, and how to perform a code review. What is Code Review?Source Code Review is a process where the complete code of a software application is divided into small parts, and then the parts are reviewed by senior developers and managers. The primary goal of Code Reviewing is to track errors and early bugs the ensure that the source code is in its cleanest possible state. This process is a crucial part of the DevOps cycle and is generally conducted before the QA testing. Why Should You Always Review Code?Listed below are some of the advantages of the code review
Difference between Code Review and TestingCode Reviewing is the process of code exemption by leads and managers. This could lead to the detection of bugs, compliance with industry standards, simplifying the code structure, etc. The main aim is to improve the quality of the code and to ensure the proper functioning of the code. On the other hand, Testing Phase is a considerable part and time-consuming process of software development. Code review involves reviewing several sections of the code to check for structural issues, minor bugs, etc. The testing phase will involve the code being executed multiple times to check if all the features and functionalities are working as intended. Can Code Review replace testing?This scenario is not possible at all. Even if you have a stringent code review process in place, you cannot deploy the final product without getting it tested. The reason is:
The Code Reviewing ensures that:
Hence, code review and testing are crucial for an efficient software application development process, and one cannot replace the other. How can QA participate in Code Review?The QA code review process comes under the static testing process, which QA generally conducts for the early detection of bugs. Testers have solid observational skills that ensure that the code follows all the essential protocols. Some of the tips for QA testers to participate in code review are:
Code Review ChecklistA code review checklist can help you conduct the process in a structured manner and ensure that you don’t miss out on anything important. Here is a must-have list for code reviews:
Code Review is an essential step in the application development process. The QA code review process should include automation testing, detailed code review, and internal QA. Automation testing checks for syntax errors, code listing, etc. These tasks save time and effort when carried out by automated methods. The detailed code review process includes identifying bugs, standard compliance violations, readability, etc. And the Internal QA process ensures that the code meets the functional requirements. Code review helps in knowledge sharing, identifying bugs, maintaining compliance, increasing collaboration, and enhancing security. Therefore development teams should not skip this. What comes first code review or testing?Code Review is an integral process of software development that identifies bugs and defects before the testing phase.
Should code review happen before or after QA?Generally, code review happens only after automated testing. It's not efficient for a human to review code that is not yet up to the robots' standards. QA can be automated with tools and services like automated testing, visual regression, code level tests, automated browser testing, etc.
Should code review include testing?"Code review is just that; code review. It is another developer checking your code changes, pretty briefly but still checking it, to make sure you did not miss something obvious. So code review should not include manual testing.
What is the order of steps for code review process?Read all code written by a developer over the last few days. Understand the changes. Offer actionable feedback. Follow up with discussion.
