Weirdness with cabal, HTF, and HUnit assertions
- by rampion
So I'm trying to use HTF to run some HUnit-style assertions
% cat tests/TestDemo.hs
{-# OPTIONS_GHC -Wall -F -pgmF htfpp #-}
module Main where
import Test.Framework
import Test.HUnit.Base ((@?=))
import System.Environment (getArgs)
-- just run some tests
main :: IO ()
main = getArgs >>= flip runTestWithArgs Main.allHTFTests
-- all these tests should fail
test_fail_int1 :: Assertion
test_fail_int1 = (0::Int) @?= (1::Int)
test_fail_bool1 :: Assertion
test_fail_bool1 = True @?= False
test_fail_string1 :: Assertion
test_fail_string1 = "0" @?= "1"
test_fail_int2 :: Assertion
test_fail_int2 = [0::Int] @?= [1::Int]
test_fail_string2 :: Assertion
test_fail_string2 = "true" @?= "false"
test_fail_bool2 :: Assertion
test_fail_bool2 = [True] @?= [False]
And when I use ghc --make, it seems to work correctly.
% ghc --make tests/TestDemo.hs

But when I use cabal to build it, not all the tests that should fail, fail.
% cat Demo.cabal
...

What's going wrong and how can I fix it?
