have_many(:model).validate(false) causes a false positive test

[kiskoza]

I run into a problem where I had to make sure that an association has a validate: false on the association. I started it with writing a test for it, but it passed immediately without making the required code change.

I created this code snippet to reproduce the issue: https://gist.github.com/kiskoza/da2b4a0ba6930e9454403ea36e3fd73c

I think the problem is that in my case there weren't a validate option prior to the task. When it was validated as a boolean, the nil value was simply converted to false
