Presentations

The Walking TDD

8:30 AM MDT

Didn't you hear the news? TDD is dead. Yet many developers rely on it for quality code. Come join the zombie apocalypse and learn and understand TDD, what sets it apart from unit testing after the fact, what to do when you need to update code, effective mocking, automatically generating test data and lots of it, leaving code alone and respecting your work, and more

This presentation will cover:

  • What is TDD?
  • Benefits of TDD
  • How to TDD
  • Mocking
  • The Great TDD Debate
  • Opinions of TDD from Industry Leaders
  • JVM Testing Tools
  • JVM Testing Languages
  • Testing Static Calls
  • Updating Code

Making Java Bearable with Guava (2015 Edition)

1:30 PM MDT

This 2015 presentation covers the Guava library developed by Google. Guava provides collection extensions to the Java Collection API and, along with this, a cornucopia of time-saving utilities that bring Java as close as possible to some of the more functional
and/or dynamic language competitors like Scala, Ruby, and Clojure. Why a brand spanking new 2015 version of this presentation? Well, there more new stuff to learn and use!

This presentation covers briefly on the tried and true stuff like functions, predicates and how they interact with Java 8. It covers how to use new collection constructs that make life easier, including MultiMap, BiMaps, and MultiSets, immutable collections, handling Futures with callbacks and shutdowns, caches, and then we will dwell on tons of the newer features that came with Releases 16, 17, and 18.

Learning 5 JVM Languages in the Next 5 Years

8:30 PM MDT

Take control of your knowledge portfolio and be in demand! Your command of the top JVM languages; Java 8, Groovy, Scala, JRuby, and Clojure; will set you apart from the rest. This presentation will introduce each of these languages, highlight common ground, and show some stark differences.

This presentation will cover:

  • How to install each of the JVM languages
  • Describe the “functionality” of each of the languages
  • Expressiveness vs. Terseness of each language
  • How each language handles mutability
  • How each language handles concurrency
  • Amazing tricks of each language
  • Comparison of language typing
  • Comparison and contrast of language performance
  • Each language's killer app
  • Analysis of the language culture and where to get help?
  • Tips on how to start learning and keep learning with a busy schedule

Scala for Java Developers (1/2) (Laptops Optional)

1:30 PM MDT

Scala for Java Developers is a full live code and fast paced presentation and workshop (laptops optional), and this is all about the Scala language.

Scala is a wonderful functional/hybrid language. It will become one of the 5 languages that you will need to know to be a highly successful JVM developer in the very near future (others being Groovy, Clojure, Java 8, and JRuby). Scala, as opposed to some of the other languages, has quite a learning curve. This presentation was built for questions. We will start with some basics, how this presentation will flow and end will be up to you, the audience. Bring your intellect, curiosity, and your questions, and get ready for some Scala. Laptops optional so you can try stuff out on your machine and create questions of your own!

Scala for Java Developers (2/2) (Laptops Optional)

3:15 PM MDT

Scala for Java Developers is a full live code and fast-paced presentation and workshop (laptops optional), and this is all about the Scala language. This is Part 2, continuing where we left off from Part 1.

Books

Testing in Scala

Testing in Scala

by Daniel Hinojosa

If you build your Scala application through Test-Driven Development, you’ll quickly see the advantages of testing before you write production code. This hands-on book shows you how to create tests with ScalaTest and the Specs2—two of the best testing frameworks available—and how to run your tests in the Simple Build Tool (SBT) designed specifically for Scala projects.

By building a sample digital jukebox application, you’ll discover how to isolate your tests from large subsystems and networks with mocking code, and how to use the ScalaCheck library for automated specification-based testing. If you’re familiar with Scala, Ruby, or Python, this book is for you.

  • Get an overview of Test-Driven Development
  • Start a simple project with SBT and create tests before you write code
  • Dive into SBT’s basic commands, interactive mode, packaging, and history
  • Use ScalaTest both in the command line and with SBT, and learn how to incorporate JUnit and TestNG
  • Work with the Specs2 framework, including Specification styles, matchers DSLs, and Data Tables
  • Understand mocking by using Java frameworks EasyMock and Mockito, and the Scala-only framework ScalaMock
  • Automate testing by using ScalaCheck to generate fake data
