The use of multiple dispatch in Julia’s standard library and user-written functions presents a challenge for automated techniques of generating test data. In order to exercise all the methods that implement a function, the generation technique must generate test data with diverse data types, but traditional techniques typically focus solely on diverse data values and implicitly assume a constant data type. In this talk, I will demonstrate our solution to this challenge which automatically learns an effective probability distribution over types and methods that create instances of these types. I will explain how we used this approach to fuzz-test some common arithmetic and string functions in the Julia standard library, in the process identifying three faults.
