debugger changes test behavior

[Michel Pigassou]

Hi.

Have you ever had this problem where your test fails where it should succeed, and you just add a debugger in your controller or model, and then it succeeds?

I could observe this behavior under different Ruby versions, 1.9.3 and 2.0.0, with Rails 3 and 4.
I have no idea what could cause this, but since I have been noticing this many times I guess I'm not the only one. Am I?

That could be anything, for example timing in multithreaded applications
or the debugger changing meta programming effects.
