It is usually incorporated at any stage into the software development lifecycle after the “code development” phase and before running tests. Also, it includes common developer errors which are often found during PR reviews. This is usually done by analyzing code with a given set of rules or coding standards and it address code vulnerabilities, code smells, test coverage, and other coding standards. Static code analysis is a way to check application source code even before the program is run. In this post, we are going to focus on static code analysis, as it can be automatized and produce results even without any input from the developer. There are different tools for dynamic code analysis, such as Microsoft IntelliTest, Java Pathfinder, or KLEE for C/C++. It doesn’t give us a holistic view of the application, so it’s recommended to use it together with dynamic code analysis. Here we analyze source code to identify different kinds of flaws. The primary objective is to find issues and vulnerabilities in software that can be debugged.Īnother kind of analysis is static code analysis. This kind of analysis helps us to find issues related to application integration with database servers and other external services. When we talk about checking for code quality in terms of tools, there are two options here: dynamic and static code analysis.ĭynamic code analysis is actually analyzing applications during execution, where we analyze code for reliability, quality, and security. Some benefits of code reviews: Tools to check for code quality In a typical code review, we should check for:Ĭode reviews can be implemented in different ways, from single-person reviews to pair programming (much better), however, all of these methods are usually time-intensive, so code quality check tools can automate that process. It is important to do code reviews, to improve coding skills, but also it represents a great knowledge-sharing tool in a team. Then, one of the team members needs to review the code. Code review in particular means an approach of reviewing other programming code for mistakes and other code metrics, but also if all requirements are implemented correctly.Ĭode review usually starts with a submitted Pull Request (PR) for code to be added to a codebase. It enables us to reduce development costs, by catching issues in the code earlier, but also as a communication and knowledge sharing tool. These standards usually define the following:Ĭode reviews are a helpful tool for teams to improve code quality. by a company - Microsoft or per language, e.g. There are different examples of code standards, e.g. This ensures consistent code across all team members. Style guides are company standard conventions, usually defined per programming language, as best practices that should be enforced. By using it, we can easier use and maintain our code. Coding standardsĬoding standards and code styles provide uniformity in code inside a project or a team. To have a similar view to the same topic of high-quality code, we need to impose some standards and guides. However, even though we know some attributes and characteristics of high-quality code, they can mean a different thing to different people, or they can have a different view on priorities against them. Functional - it does what we say it does.Īnd there are probably more characteristics of good code, but these are making the core of the high-quality code.While there is no widely adopted definition of high-quality code, we know some of the characteristics of good code: We mainly refer to the attributes and characteristics of code. When we talk about code quality, we can think of different aspects of it.
