How do I assert that an Option contains something in zio-test?

Question

I tried

assert(anOption)(contains("x"))

But that only works for Iterables such as List or Seq.

@derpy, people from different age group, background and technical level use SO to get guidance. A lot of students and junior level devs/people are there who can't understand one-line code answers. Its better to properly describe question or answer that can easily be understandable to a large number of people. – Muhammad Tariq Apr 30 '21 at 10:13

Could also be assert(anOption)(equalTo(Some("x"))) - just using equality. Or if you want to use contains: assert(isTrue(anOption.contains("x"))) using the contains operator on option

Yeah, the first one works well and is simpler than the accepted answer. `isTrue` is not great because the failure message it will produce won't be descriptive. – Thilo May 03 '21 at 23:54
