Static Code Analysis is one component of software code testing and debugging. Static code analysis means that the code is analyzed without actually running the program. The idea behind this kind of debugging is to understand the structure of the code and make sure that it adheres to industry standards.
We’ve collected videos, features, and capabilities below. Take me there.
Static Code Analysis (also called static analysis or source code analysis) is a way to debug software code before the program is executed. The code is automatically compared to coding rules and industry standards to ensure compliance. Static code analysis occurs in the creation phase, before testing begins.
Static code analysis analyzes the structure of the code, looking for code errors, malicious software, and other security flaws such as back doors. These tools frequently allow developers to hone in on portions of the code that might be problematic, rather than simply finding flaws.
The goal of both static coding and dynamic coding is to discover coding errors. The difference is where this discovery takes place. Static coding uncovers errors before testing the software, whereas dynamic coding uncovers errors during the testing phase, including any errors that the static code analysis failed to uncover.
Dynamic code analysis analyzes how code interacts with other components, such as application servers and SQL databases to ensure the code is secure. Most developers choose to implement both kinds of testing to ensure the most robust code.
Static code analysis is not 100% accurate and sometimes returns false positives or false negatives. However, it has numerous benefits, including:
Most static code analysis software on the market today offers the following features:
When choosing a static code analysis solution, there are a few factors you should consider.
Dashboards: Static code analysis tools include dashboarding features for visualization. Some include detailed dashboards, while others expect you to export data to another intelligence tool. Be sure to choose a solution that has the dashboarding features you need.
Integrations: Some static code analysis tools offer integrations with other code tools, such as GitHub. If you plan to make use of these integrations, you should choose a tool that offers them natively.
Supported Languages: Almost all static code analysis tools support multiple languages, but they don’t always support all languages. When choosing a solution for your business, make sure the languages you use are supported.
The price of static code analysis software ranges from free to several thousand per year. There are several open source static code analysis solutions on the market. For those needing more robust solutions, more programming languages, and support, expect to pay between $10 and $65 per user per month. Enterprise level users will need to obtain a custom quote based on the number of users and scans anticipated per month.
