Tests pass in GHCI but fail in cabal test - haskell

Question

UPDATE After I added the haskeline dependency, the tests passed.
It appears that cabal test cannot find my test cases even though cabal build runs fine. Below is the output of cabal test (which fails), and then the output of running the test executable's main in GHCI (which passes).
cabal test
Running 1 test suites...
Test suite test-one: RUNNING...
test-one: <stdin>: hGetLine: end of file
Test suite test-one: FAIL
Test suite logged to: dist/test/one-0.1.0.0-test-one.log
0 of 1 test suites (0 of 1 test cases) passed.
main
Cases: 3 Tried: 3 Errors: 0 Failures: 0
Counts {cases = 3, tried = 3, errors = 0, failures = 0}
Here's the test code that produces these outputs:
module Tests (
main
) where
import Data.Char
import Control.Monad
import System.IO
import System.Directory
import Test.HUnit
import Test.QuickCheck
import Main (four)
test1 = TestCase $ assertEqual "test upCase" "FOO" (map toUpper "foo")
test2 = TestCase $ assertEqual "testing that the result is 4" 4 4
test3 = TestCase $ assertEqual "testing that 4 is 4" four 4
tests = TestList [TestLabel "test1" test1, TestLabel "test2" test2, TestLabel "test3" test3]
main = runTestTT $ tests
What should I change to please cabal?
My .cabal file contains:
executable one
main-is: Main.hs
other-modules: Utils
build-depends: base ==4.6.*, mongoDB ==1.4.*, mtl ==2.1.*, directory ==1.2.*, text ==0.11.*, HUnit ==1.2.*, QuickCheck ==2.6.*
hs-source-dirs: src, tests
Test-Suite test-one
type: exitcode-stdio-1.0
main-is: Tests.hs
hs-source-dirs: src, tests
build-depends: base ==4.6.*, mongoDB ==1.4.*, mtl ==2.1.*, directory ==1.2.*, text ==0.11.*, HUnit ==1.2.*, QuickCheck ==2.6.*

You should rename the module Tests to Main, otherwise the test executable won't be built. Quoting the Haskell Report:
A Haskell program is a collection of modules, one of which, by
convention, must be called Main and must export the value main.
Otherwise I don't see anything obviously wrong. Here's a working example based on your code: https://gist.github.com/23Skidoo/8019225
Perhaps you're using an old version of cabal? Consider upgrading to 1.18.
