Is there a test one can perform to quickly determine what type of regression (linear vs. non-linear) will best fit the relationship between two variables?

i.e. How can one quickly determine the most probably relationship between two variables (like a sort of "probability of fit" test)?

(Linear vs. non-linear...)
