We know that Code Reviews are a Good Thing. We probably have our own personal lists of things we look for in the code we review, while also fearing what others might say about our code. How to we ensure that code reviews are actually benefiting the team, and the application? How do we decide who does the reviews? What does "done" look like?
In this talk, Trisha will identify some best practices to follow. She'll talk about what's really important in a code review, and set out some guidelines to follow in order to maximise the value of the code review and minimise the pain.
The webinar recording also has an associated blog post which covers Q&A raised.
