Support testing

[vlatkoB]

There seems to be no support for testing in haskell-mode. I tried this:

(defun haskell-process-cabal-repl-test ()
  (interactive)
  (setq haskell-process-args-cabal-repl '("test"))
  (haskell-process-load-or-reload)
  (setq haskell-process-args-cabal-repl '("--ghc-option=-ferror-spans" "--with-ghc=ghci-ng"))
 )

and can run tests.

What would be the proper way to implement it? Maybe also add the function to run a test at point?

Sure there is: haskell-session-change-target and then enter in the name of the test you want to edit/evaluate/build/etc.

That said, @mrkkrp's ebal has some support for running test suites.

Thanks for pointing me to haskell-session-change-target. I do not recall I read about it in docs.

ebal looks interesting.

@vlatkoB: Can you try to describe the workflow in document haskell-mode.texi?

[vlatkoB]

I added a small description. (Not sure why PR is not displayed here.)

Was this what you meant?
If yes, please review it. English is not my mother tongue, and see if style suits you.

Would be nice if haskell-session-change-target would display ido choice of sections, instead of typing the section name.

[ivan-m]

Maybe grab the code that does that from https://github.com/mrkkrp/ebal ?

Just created a PR with a new function that enables choosing a target from available targets in .cabal file..
