Windows 7上的Cabal测试

Question

I am trying to follow the examples from here http://www.haskell.org/cabal/users-guide/#test-suites

When I run cabal test it throws this error cabal: No test suites enabled. Did you remember to configure with '--enable-tests'? cabal: No test suites enabled. Did you remember to configure with '--enable-tests'?

so I try cabal configure --enable-tests and then cabal test but I now get

Running 1 test suites...
Test suite test-s3dm: RUNNING...
cabal: permission denied

What am I doing wrong?

Answer 1

You still need to actually build the tests and the program which you want to test. so you need to do cabal build after configure.

But I would agree that that error message should be something else.

Answer 2

I had the same problem that you did. The cause of it was that the test suite file wasn't getting compiled into an executable. Turned out that no matter how I configured it, Cabal didn't produce executables for modules located in some namespaces (eg Pkg.Main ) and complained about not being able to find a Main module during building phase.

The solution I found was to move both the Main module and the TestSuite module into the core src/ folder and to remove the heading module declarations in those files.

Here's how my working cabal config looks now:

name:           Pwn
version:        0.1
cabal-version:  >= 1.2
build-type:     Simple

  build-depends:   base >= 4 && < 5,
                   random,
                   containers

  hs-source-dirs:  src
  main-is:         test-suite.hs
  build-depends:

                   test-framework >= 0.4.1,
                   test-framework-quickcheck,
                   test-framework-hunit
