@ReviakinAleksey sorry for taking so long to reply. This is a great PR! Love the new test 😍 Only issue I see is it looks like the test isn’t compiling in CI: https://travis-ci.org/lift/framework/jobs/523455236#L2271

Hello @Shadowfiend, unfortunately I only test my code inside IDEA IDE, and mess up PR in first lines.
Line number 5: import net.liftweb.http.{LiftRules, LiftSession, WithLiftContext} which produce object WithLiftContext is not a member of package net.liftweb.h compilation error in sbt test.
I use WithLiftContext to render Crudify snippet in most simplest way.

Could you please give me a help hand with this PR and suggest proper way to test snippet output?

Ah, I see! WithLiftContext is part of testkit, which isn't a test dependency of the proto module's tests. This'll need some sbt fiddling… Not sure if I'll have time to do it but I'm going to try!

[ReviakinAleksey]

I think I found proper solution, test now is using S.statelessInit(Req.nil) method instead of WithLiftContext trait.

Nice! Awesome adjustment 😎 Let's rock and roll!
