BalanceSheetSpec.scala

"負数の残高にはできない" in {
  // Given
  val initA = Map(Cash -> BigDecimal(1_000_000))
  val initL = Map.empty[AccountTitle, BigDecimal]
  val entry = JournalEntry(

  // When
  val result = BalanceSheet.NotReady
    .initialize(initA, initL)
    .flatMap(_.journalize(entry))
  // Then
  result shouldBe Rejected(NonEmptyChain(NegativeBalance))
