I have a method that's declared as returning

Set<MyType>

. I'm writing a test that uses

shouldContainExactly

to test it. When I instantiate the return value as a

LinkedHashSet

it works, but when I instead instantiate it as a

HashSet

I get:

Disallowed: Set can be compared only to Set
java.lang.AssertionError: Disallowed: Set can be compared only to Set
May not compare HashSet with ArrayList
expected:<*> but was:<*>

What's going on here?

shouldContainExactlyInAnyOrder, I think

Yep, that worked, thanks

is shouldContainExactly the same as just shouldBe in this case?

I think for shouldBe you'd have to construct the

LinkedHashSet

, and it'd fail if the actual type was a subtype? But I'm not sure

That makes sense
