containsTheSameElementsAs如何在specs2中工作

Question

此代码不匹配.它是否正确？

List(1, List(2, 3, List(4)), 5) must containTheSameElementsAs(List(5, List(List(4), 2, 3), 1))

错误消息如下:

[error]   x be available for elements in a sequence
[error]    List(1, List(2, 3, List(4)), 5)
[error]      is missing: List(List(4), 2, 3)
[error]      must not contain: List(2, 3, List(4)) (specs2test.scala:98)

Answer 1

该containsTheSameElementsAs匹配唯一无二一级深,所以比赛的嵌套列表上失败List(2, 3, List(4)) != List(List(4), 2, 3).在使用此匹配器之前简单地展平嵌套对象可能更好.
