- Unit tests: Review unit tests first. Unit tests are a fantastic way to grasp how code is meant to be used by others and to learn what the expected behavior is. Are there any test gaps that should be there?
- Method arguments" Make sure arguments to methods make sense and are validated.
- Null References" (Yah yah, we know. Use F# and this goes away. We get it already.) Null references are a bitch and it’s worth looking out for them specifically.
- Conventions Consistency" Make sure naming, formatting, etc. follow our conventions and are consistent. I like a codebase that’s fairly consistent so you know what to expect.
- Disposables: Make sure disposable things are disposed. Look for usages of resources that should be disposed but are not.
- Security: There is a whole threat and mitigation review process that falls under this bucket.
