Agenda

• Why code reviews?• Code review tips• What's Fisheye for?• What's Crucible for?• Fisheye answers• Crucible workflows

3

Why code reviews?

• Catch bugs and design flaws early.• Help teammates learn.• Enforce coding standards, consistency.• Ensure architecture alignment. • Review tests. 

4

When do code reviews?

• Early and Often.• Daily.• Theme: small commits, incremental changes,

frequent small reviews.• This is less work...

o Than fixing buggy bug bugs.o Than fatty reviews.o Than big bang commits.

5

Code reviews: what to look for

• Design or logic errors.• Missing parameter / pre-condition checks.• Bad/missing exception handling.• Incorrect log levels (error -> info).• Useless log messages (not enough context).• Long methods (> 20 - 50 lines of code).• Potential side effects.• Missing comments/docs on interfaces.
