I am fiddling a bit going through predicates to determine whether a certain PsiElement meets some conditions. Is there any way to write some small tests where I can play with instantiated PsiElements in order to inspect them and test my predicates?

IDEA has PsiViewer plugin, so that could be one.
You can also try testing with arrow meta, it allows you to write snippets as a string, compile them and test output.

That is exactly what I needed, thank you!

Also take a look at the Quotes tests in meta which test different element of the AST

@Nico I spent a day to figure out what works for me. I have put it down as a blog post. Hope it helps.
