scala - 如何在specs2中将输入和结果定义为DataTable？

我试图在specs2中使用DataTables来定义输入以及结果应该是什么样子并且无法使其工作。我在想类似于以下代码的内容：

class MySpec extends Specification with DataTables {

"A Container" should {
"after data is added container should have the following data" in new TestContainer {
  "a"  | "flag" | "d"   |
  100  ! 1      ! "abc" |
  300  ! 1      ! "abc" |
  200  ! 0      ! "xyz" |>
  { (a, flag, d) =>
    container.add(Data(a, flag, d)) must not(throwA[Exception])
  } and
  "a"  | "flag" | "d"   |
  300  ! 1      ! "abc" |
  100  ! 1      ! "abc" |>
  { (a, flag, d) => ????
  }
}
}

免责声明：我是scala和spec的新手。为了简洁起见，省略了一些代码。

最佳答案

在对specs2有了更好的了解之后，我想到了一个解决方案：

class MySpec extends Specification with DataTables {

"A Container" should {
"after data is added container should have the following data" in new TestContainer {
  "a"  | "flag" | "d"   |
  100  ! 1      ! "abc" |
  300  ! 1      ! "abc" |
  200  ! 0      ! "xyz" |>
  { (a, flag, d) =>
    container.add(Data(a, flag, d)) must not(throwAn[Exception])
  }
  val state = container.list
  "a"  | "flag" | "d"   |
  300  ! 1      ! "abc" |
  100  ! 1      ! "abc" |>
  { (a, flag, d) => state must contain((a, flag, d))
  }
}
}

如果顺序很重要，则第二个表可以将元组添加到某个列表中，然后在处理第二个表后比较2个列表。请注意，此行为在2.3中已损坏，但在2.4-SNAPSHOT中有效。
