In this episode, I explore a number of topics with Daniel Hinojosa. We talk about skills that should spread beyond developers, look back on our careers and talk about our techniques for making important information stick as we're learning and teaching.


Remote Work and Thoughts on Travel
May 10, 2017

Many of the NFJS speakers are independent and frequently work remotely. This is a trend we're seeing more and more in our industry. Michael Carducci interviews speaker and independent consultant Daniel Hinojsoa on his thoughts on remote work and the conversation turns to our thoughts and experiences on air travel.

Testing in Scala

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
