test Task

I'd like to test a Task. Is this already possible?

No, it’s not possible right now. This will require some planning, I think, since Tasks can perform effects. Are you thinking more like having a Task x a, performing it, and making assertions against the ultimate result, or are you thinking more along the lines of testing its actual effect? ​

I work on a native package that uses Tasks to calculate the result of asynchronous functions. I'm mainly interested in making assertions against the ultimate result. But I also like to test if errors (effects) appear as expected.

This is something I'd like to add in the medium term. I'm not yet sure of the best way to go about it, I have some ideas, but it will surely involve adding Native code, which is a somewhat significant amount of work.

I would love to see this feature! Tasks are the hardest part of Elm to debug. You can't evaluate them at the REPL or in test suites rn :cry:
