less-arbitrary: Linear time testing with variant of Arbitrary class that always terminates.

[ bsd3, library, web ] [ Propose Tags ]

Ever found non-terminating Arbitrary instance? Ever wondered what would be a runtime cost of particular Arbitrary instance?

Never let it bother you again: this variant of Arbitrary is automatically generating instances, and allows you to see predictable linear time generators for most types (providing that you have any terminating constructor, that is constructor that does not go deeper into the data structure.)

Usage: ``` import Test.LessArbitrary

data MyDataType = ... deriving (Show, Generic)

instance LessArbitrary MyDataType instance Arbitrary where arbitrary = lessArbitrary ```

Readme for less-arbitrary-

[back to package description]

To build this you need:

  • Haskell Stack
  • for documentation:
    • pandoc
    • xelatex with standard science article packages
      • easiest to get as MacTeX on Mac
      • apt-get install -y texlive-recommended on Ubuntu
  • enTangleD for code generation (if you want to edit .md source file)

To read more, look into less-arbitrary.md which is literate source file.
