I am trying to assert the condition but getting error.
I have result of type Either[CaseClass[Array[String]]] with value: Right(CaseClass(Array("value")))
When i do :
result should equal(Right(CaseClass(Array("value"))))
It gives me:
Right(CaseClass([Ljava.lang.String;@6ed4e733) did not equal Right(CaseClass([Ljava.lang.String;@43553bf0))
Array is not a true Scala collections and behaves differently, for example
List(42) == List(42) // true
Array(42) == Array(42) // false
where we see array is not compared structurally. Now ScalaTest does provide special handling for Array which would indeed compare them structurally
Array("") should equal (Array("")) // pass
however it does not work when Array is nested in another container
case class Foo(a: Array[String])
Foo(Array("")) should equal (Foo(Array(""))) // fail
True Scala collections, such as List, do not suffer this problem
case class Bar(a: List[String])
Bar(List("")) should equal (Bar(List(""))) // pass
There is an open issue Matchers fail to understand Array equality for Arrays wrapped inside a container/collection #491 to address deep equality checks for Array however for now I would suggest switching to List instead of Array. Another options is to provide your own custom equality designed to handle your specific case.
