== Problem: ==
cabal test does not tail standard output of the running test executable.
Instead, any output from the executable is output right at the end of the
test process in one batch.
== Motivation: ==
It is incredibly useful to have cabal test tail the stdout of the test
executable currently being executed such that CI tools such as TeamCity
can be made to record the time it takes to run individual tests.
== Reproduction: ==
Run the following simple executable as a test executable with
{{{cabal test --show-details=always}}}
{{{
module Main where
import Control.Concurrent
delay = 5000000
main = do
putStrLn "First message"
threadDelay delay
putStrLn "Second message"
threadDelay delay
putStrLn "Third message"
threadDelay delay
}}}
Instead of outputting each line ("First/Second/Third message") five
seconds after another, all three lines are output along with test result
reporting all at once at the end of the test suite.
