Readme for tasty-kat

Readme for tasty-kat-0.0.3


Build Status BSD Haskell

Tasty-kat provides support for KAT (Known Answer Tests) testing. KAT files provides input and output tests for some functions for example, for testing the following function:

r == a + b

A KAT file could be:

[2 digits addition]

a = 10
b = 20
r = 30

a = 11
b = 21
r = 32

This is somewhat similar to the tasty-golden package, but instead of generating files and comparing output file to a golden file, tasty-kat loads input and output in test vectors and run specific function on it.

import Test.Tasty
import Test.Tasty.KAT
main = do
    kat <- testKatLoad "path/to/KAT" katLoaderSimple
    defaultMain [ testKatDetailed "kat-name" kat testKat ]
  where testAddition group kvs =
            case sequence $ map (flip lookup kvs) ["a","b","r"] of
                Nothing      -> error "invalid vector"
                Just [a,b,r] -> let a = read as :: Int
                                    b = read bs :: Int
                                    r = read rs :: Int
                                 in return (a + b == r)

The detail output with 'testKatDetailed' looks like:

      1:    OK
      2:    OK
      1:    OK
      1:    OK
      1:    OK
      2:    OK

The grouped output with 'testKatGrouped' looks like:

    add:    OK
      2 tests succeed
    sub:    OK
      1 tests succeed
    add:    OK
      1 tests succeed
    base64: OK
      2 tests succeed
