Hello! I'm the author of the Cabal test code. This is a known issue; I
have submitted a patch that should appear in the next version of

Note that Cabal is not actually running your test multiple times,
rather, the problem is that the test log files are not overwritten
between invocations of 'cabal test'. Until the fixed version of Cabal
is released, you can run 'cabal clean' before 'cabal configure' to
delete the test logs between 'cabal test' invocations and clean up the
spurious output.
