How to test ?

[leobenkel]

Hello,

I have been writing a project using Scalaz-Zio and using IO[A] throughout the project.

However, I am puzzled on how to write test for it.

How do I use assert(true, ...) when my value is IO[Error, Boolean] ?

Or assert(HaveSucceed, ...) ?

Thank you.

If your test class extends RTS, you can use unsafeRunSync on your IO to run it and receive an ExitResult[E, A] when it's completed. You can then use pattern matching on the ExitResult (or use toEither) to check if it was a success or failure.

You can also use unsafeRun directly to get an A but it will throw an exception in case of error.
