tasty-expected-failure

What is this?

With the function expectFail in the provided module ExpectedFailure, you can mark that you expect test cases to fail, and not to pass.

This can for example be used for test-driven development: Create the tests, mark them with expectFail, and you can still push to the main branch, without your continuous integration branch failing.

Once someone implements the feature or fixes the bug (maybe unknowingly), the test suite will tell him so, due to the now unexpectedly passing test, and he can remove the expectFail marker.

The module also provides ignoreTest to avoid running a test. Both funtions are implemented via the more general wrapTest, which is also provided.

Why is this not provided by tasty?

<rant>

The author of the tasty library prefers to provide a minimal experience in the tasty library, instead of a batteries-included approach, and chose not to include these 39 lines of code in tasty. See the issue for the discussion.

Instead I wrote 37 lines of cabal file, a similar number of lines of README, created a git repository, created a travis file, run travis to figure out on what versions it builds (something that would have happened automatically with a pull request for tasty), upload to hackge, add to stackage.

Furthermore, there is little discoverability: If it were part of the tasty API, users would stumble over it. Now they likely won’t. And if they do, they have to worry about whether it is still in sync with tasty, they have to add it to their build-depends, they have to import yet another module. Distribution packagers will have yet another package where they have to create the packaging, check the copyright, and run autobuilders for.

Sigh.
