Naming things is famously one of the hard things in computer science.

One simple technique I use to avoid bad naming is something I think of as "the pairing test".

Take a piece of code that someone is likely to want to understand as a whole. It could be a group of classes that interact to make a feature, or the methods within a class.

Picture a list of the class or method names running down the left-hand side, and a randomly sorted list of explanations of what they do running down the right-hand side.

Now, imagine that you asked someone who did not write this code to draw lines to pair up the names with the explanations. Could they confidently do it?

If not, your naming probably stands to be improved.

In the above example, names like PersistItem and BuildItem might be more distinct.

I don't actually tend to draw these out on paper – it's usually as simple as noticing that two interacting things that are different have names that are interchangeable. But the model in my head is of these visual pairings.
