无需运行即可构建haskell堆栈测试

Question

I've made a very simple project with a failing test suite https://github.com/k-bx/noruntests-play

Now when I run stack --test --no-run-tests build I would expect it to build the project, but not run the tests. Instead, it runs the tests:

➜  noruntests-play git:(master) stack --test --no-run-tests build
noruntests-play-0.1.0.0: test (suite: test)

test: error
CallStack (from HasCallStack):
  error, called at tests/Tests.hs:4:8 in main:Main

Test suite failure for package noruntests-play-0.1.0.0
    test:  exited with: ExitFailure 1
Logs printed to console

What am I doing wrong here? Thank you!

Answer 1

You should put build option before --test like this:

$ stack build --test --no-run-tests

I'm not sure whether it's bug or feature. You can open issue here if you're interested in feedback from developers. Personally for me it seems strange to pass --test before build . In some reasonable sense --test is subpart of build and subparts or options are usually specified to the right of main option.

Also there's shorter version of what you want (because build --test is just test ):

$ stack test --no-run-tests
