      Type:  defect         |       Status:  new   
  Priority:  normal         |    Milestone:        
 Component:  Cabal library  |      Version:  1.14.0
  Severity:  normal         |     Keywords:        
Difficulty:  unknown        |   Ghcversion:  7.4.1 
  Platform:  Windows        |  
----------------------------+-----------------------------------------------
 When running "cabal test" on a project configured with "cabal configure
 --enable-tests --enable-library-coverage", the hpcdir for test suites
 points to dist/hpc/mix/PackageName, not dist/hpc/mix/TestSuiteName.

 This results in an aborted run:
 {{{
 PS C:\Users\Albert Fong\Repositories\working\projects\Simple>
 runhaskell.exe .\Setup.hs test -v
 Running 3 test suites...
 Test suite Tests3: RUNNING...
 Test suite Tests3: PASS

 Fong\Repositories\working\devenv\tools\ghc-7.4.1\bin\hpc.exe markup

 dir=dist\hpc\mix\Simple-0.1.0.0 --destdir=dist\hpc\html\Tests3
 --exclude=Main
 hpc.exe: can not find Library in ["./dist\\hpc\\mix\\Simple-0.1.0.0"]
 PS C:\Users\Albert Fong\Repositories\working\projects\Simple>
 }}}

 Note the hpcdir during build ("-fhpc -hpcdir dist\hpc\mix\Tests3") is not
 what's used during test ("--hpcdir=dist\hpc\mix\Simple-0.1.0.0")

 }}}

 Here's the layout of the dist/hpc folder:

 {{{
 dist\hpc\mix
 dist\hpc\mix\Simple-0.1.0.0
 dist\hpc\mix\Simple-0.1.0.0\Simple-0.1.0.0
 dist\hpc\mix\Simple-0.1.0.0\Simple-0.1.0.0\Library.mix

 dist\hpc\mix\Tests2
 dist\hpc\mix\Tests2\Library.mix
 dist\hpc\mix\Tests2\Main.mix
 dist\hpc\mix\Tests3
 dist\hpc\mix\Tests3\Library.mix
 dist\hpc\mix\Tests3\Main.mix
 dist\hpc\tix
 dist\hpc\tix\Tests3
 dist\hpc\tix\Tests3\Tests3.tix
 }}}

 The double nested "Simple-0.1.0.0" under mix may be another issue as well.

 A cabal project used to repro this issue is attached.
