Techniques and solutions are described for automatically analyzing code for code principle violations. A code analysis can be configured that includes one or more tests for one or more code principle violations. The code analysis can be applied statically, against previously generated code, or can be conducted in a dynamic manner as code is being written or edited. Code, such as automatically generated code, can be excluded from analysis, or reports of analysis results. When a code principle violation is detected, the violation can be displayed to a user. Information regarding correcting the violation can be displayed. In some cases, a code principle violation can be automatically corrected. Code violations can be classified, such as by severity, and can be associated with particular code, such as code packages or objects, or particular developers or development groups. Reports can be prepared summarizing changes in code principle violations over time.
