Static Analysis: A Complete Guide to Code Quality. Here's the short version.

Static analysis examines source code without running the program. It helps teams find bug-prone patterns, complexity hotspots, and some security anti-patterns early.

What static analysis is. Static analysis builds a structural model of code (AST, symbols, control flow where available) and applies rules. Results are diagnostics with locations and severity — not guaranteed proof of runtime failure.

Here's an example: Pattern many analyzers flag.

How static analyzers work. First, parse source into syntax trees. Second, resolve types and symbols when semantic analysis is available. Third, evaluate rules and heuristics. Fourth, report findings for developer triage.

Static analysis vs linting vs dynamic testing. Linting — often style and lightweight bug patterns at file scope. Static analysis — deeper rules, cross-file checks in advanced tools. Dynamic testing — observes runtime behavior; complements static checks. Security SAST — focused vulnerability patterns; still needs DAST and review.

Want to find these issues in your own code? Connect your GitHub repository to CodeInspector. You'll get findings with the file, line, severity, and a recommended fix, plus HTML and PDF reports for your team. Start free at codeinspector.app.
