Spek - A Specification Framework
Your typical test code Here’s some typical test code found in many codebases @Test public void testCalculateTaxRate() { TaxRateCalculator calculator = new TaxRateCalculator(); Int value = calculator.calculateRate(200, 10); assertEquals(300,value); } This code suffers from several issues. Under what conditions is the tax rate calculated? What exactly is it doing? What is the expected outcome? Being
ScalaとGoogle Collectionsで関数オブジェクト - かとじゅんの技術日誌
あけましておめでとうございます。 年末年始はいかがでしたか？私は大晦日から実家の兵庫に向かう道中、滋賀で大雪に見舞われまして、10時間ぐらい立ち往生して車中泊という幸先悪い年越しでしたorz さて、今日は関数オブジェクトの話です。関数オブジェクトといえばScalaですね。 たとえば、PersonNameの集合に対して、ある条件に該当するPersonNameのインスタンスだけを取得したい場合に、以下のような関数を使うとさくっと取得できます。filterメソッドのところです。 scala> case class PersonName(firstName:String, lastName:String) defined class PersonName scala> import scala.collection.immutable.HashSet import scala.collection

Play Framework - Build Modern & Scalable Web Apps with Java and Scala
Play Framework makes it easy to build web applications with Java & Scala. Play is based on a lightweight, stateless, web-friendly architecture. Built on Pekko (Play 3) and Akka (Play 2), Play provides predictable and minimal resource consumption (CPU, memory, threads) for highly-scalable applications. Developer friendly. Make your changes and simply hit refresh! All you need is a browser and a tex

Understanding actor concurrency, Part 2: Actors on the JVM
I’ll use the schoolyard game Rock-Paper-Scissors as a reference application and implement it in each library to demonstrate the features and differences. (You can download the source code anytime.) Each implementation uses two Player actors and a Coordinator actor. The Coordinator requests each player to play, and each Player replies with Rock, Paper, or Scissors. The Coordinator accepts the respo
