テスト ケース内で暗黙的な関数を呼び出そうとしていますが、Eclipse UI がそれを認識できないようです。 2
何か不足していますか？
コード
package com.scala.dsl
object TradeDSL {
abstract class Instrument(name: String) { def instrumentName: String }
case class Stock(name: String) extends Instrument(name) {
override val instrumentName = "EQUITY";
}
case class Bond(name: String) extends Instrument(name) {
override val instrumentName = "BOND";
}
abstract class TransactionType { def value: String}
case class Buy() extends TransactionType {
override val value = "BUY"
}
case class Sell() extends TransactionType {
override val value = "SELL"
}
class PricingStrategy(order: Order) {
def defaultPricing(): Int = order.quantity * order.price
def brokeragePricing(): Int = order.quantity * order.price + 100
}
implicit def orderPricing(order: Order) = new PricingStrategy(order);
case class Order(price: Int = 0, instrument: Instrument = null, quantity: Int = 0, totalValue: Int = 0,trn: TransactionType = null, account: String = null ) {
def maxUnitPrice(p: Int) = copy(price = p)
def to(i: Tuple2[Instrument, Int] ) = copy(instrument = i._1, quantity = i._2)

def using(pricing: (Int, Int) => Int) = {
copy(totalValue = pricing(quantity, price))
}
def forAccount(a: String)(implicit pricing: (Int,Int) => Int) = {
copy(account = a, totalValue = pricing(quantity,price))

}
}

.brokeragePricing でコンパイル エラーが発生する プロジェクトをクリーンアップして Eclipse を再起動しようとしましたが、すべて無駄でした。
