What’s the idiomatic way to make list assertions using matchers? That is, having List<T> and a Matcher<T>, what’s the best way to check something like List<T>.shouldContainInOrder(List<Matcher<T>>)?

[sam]

Are you asking how to make your own ?

[wasyl]

Or whether there is some existing utility/way to efficiently match elements in a list 🙂

[wasyl]

Ideally I wanted to have something that’d let me reuse all the existing list matchers, like shouldHaveSingleElement, shouldContainInOrder etc., only not with specific instances but with matchers

[sam]

Maybe inspectors can help

[wasyl]

I don’t see a reference to Inspector*, is it part of Arrow extensions?

[sam]

list.forAll { // put shoulds here }

[sam]

list.forOne { // }

[sam]

It doesn't do ordering through

[sam]

I think what we need is shouldContainInOrder that accepts a lambda

[wasyl]

Ah, yes, this is the API I was missing! I already worked around this by creating custom equals/hashCode but the next time I have this issue I’ll look closer at inspectors, thanks 🙂
