Static analysis is a method used in software development to examine code without executing it. This process helps identify potential errors, vulnerabilities, and coding standards violations early in the development cycle. By analyzing the source code, tools can provide insights into issues that may lead to bugs or security risks, allowing developers to address them before the software is run. Static analysis tools can be integrated into the development environment, making it easier for developers to receive immediate feedback. Common tools include SonarQube, ESLint, and FindBugs. These tools support various programming languages and help improve code quality, maintainability, and overall software reliability.
