[QA.NT.1] Evaluate code quality through static testing

PDFRSS

Category: FOUNDATIONAL

Static testing is a proactive method of assessing the quality of code without needing to run it. It can be used to test application source code, as well as other design artifacts, documentation, and infrastructure as code (IaC) files. Static testing allows teams to spot misconfigurations, security vulnerabilities, or non-compliance with organizational standards in these components before they get applied in a real environment.

Static testing should be available to developers on-demand in local environments, as well as automatically run in automated pipelines. Use static testing to run automated code reviews and detect defects early on to provide fast feedback to developers. This feedback enables developers to fix and remove bugs before deployment, which is much easier and cost effective than fixing them after deployment.

Use specialized static analysis tools tailored to the type of code you are using. For example, tools like AWS CloudFormation Guard and cfn-lint are designed to catch issues in AWS CloudFormation templates. These tools can be configured to detect issues like insecure permissions, enforcing tagging standards, or misconfigurations that could make infrastructure vulnerable. Keep your static analysis tools updated and regularly review their findings to adapt to changing infrastructure security and compliance best practices.
