Static code analysis involves using tools to analyze source code for potential issues. It can find bugs, code quality issues, and other problems but is not a replacement for testing. Several experts note that combining static analysis, inspections, and testing leads to better defect removal than only using testing. Common static analysis tools include FxCop, StyleCop, ReSharper, and NDepend. Integrating static analysis into the development process can provide benefits but obstacles like resources and unrealistic expectations must be addressed.
