I was setting up a yesod scaffolded site using the yesod init command, and I named my project yesodtry. I proceeded to setup a scaffolded site using this command, which was given by yesod init:
cd yesodtry && cabal sandbox init && cabal install && yesod devel
Everything went smoothly, and I accessed the demo site at 127.0.0.1:3000. Out of curiosity, I tried to try the yesod test command. Here's the output I got:
Resolving dependencies...
Configuring yesodtry-0.0.0...
cabal: At least the following dependencies are missing:
hspec -any, yesod-test ==1.2.*
Seeing how the yesodtry.cabal file has a test section, I tried executing cabal build test, and this is the output:
cabal: Cannot build the test suite 'test' because test suites are not enabled.
Run configure with the flag --enable-tests
Ok... so it tells me to run cabal configure --enable-tests. And here's the output:
Resolving dependencies...
Configuring yesodtry-0.0.0...
cabal: At least the following dependencies are missing:
hspec -any, yesod-test ==1.2.*
I see this line in yesodtry.cabal, for the build-depends of the test-suite test "section":
yesod-test >= 1.2 && < 1.3
It seems like cabal is not installing the dependencies here. How do I do that?
Thank you.
Ok, I think I found the answer on this Haskell-cafe thread.
We have to do:
cabal configure --enable-tests
cabal install --only-dependencies --enable-tests
And the dependencies for the test-suite test section will be installed.
I then ran yesod test, and here's the last few lines of the output:
Linking dist/build/test/test ...

Hopefully this will help anyone who encounters the same problem in the future.
