Overview of this book

Scala Programming Projects is a comprehensive project-based introduction for those who are new to Scala. Complete with step-by-step instructions and easy-to-follow tutorials that demonstrate best practices when building applications, this Scala book will have you building real-world projects in no time. Starting with the fundamentals of software development, you’ll begin with simple projects, such as developing a financial independence calculator, and then advance to more complex projects, such as a building a shopping application and a Bitcoin transaction analyzer. You’ll explore a variety of Scala features, including its OOP and FP capabilities, and learn how to write concise, reactive, and concurrent applications in a type-safe manner. You’ll also understand how to use libraries such as Akka and Play. Furthermore, you’ll be able to integrate your Scala apps with Kafka, Spark, and Zeppelin, along with deploying applications on a cloud platform. By the end of the book, you’ll have a firm foundation in Java programming that’ll enable you to solve a variety of real-world problems, and you’ll have built impressive projects to add to your professional portfolio.

Packaging the application

We have now implemented some useful building blocks, and it is time to create an executable so that end users can use our calculator with their own parameters.

Creating the App object

We are going to build a simple executable around RetCalc.simulatePlan. It will take a list of parameters separated by spaces, and print the results on the console.

The test we are going to write integrates several components together and will use a full market data set. As such, it is not really a unit test anymore; it is an integration test. For this reason, we suffixed it with IT instead of Spec.
