Unit testing jsonToHttpTransaction

First, we can start by defining a case class that represents the same data as in our JSON payload. Create a new package, coinyser, and then a class, coinyser.HttpTransaction, in src/main/scala:

package coinysercase class HttpTransaction(date: String,                           tid: String,                           price: String,                           `type`: String,                           amount: String)

In Scala, if you want to use a variable name already defined as a Scala keyword, you can enclose the variable with backticks such as the type variable name in this example: `type`: String.

This class has the same attribute names with the same types (all string) as the JSON objects. The first step is to implement a function that transforms a JSON string into Dataset[HttpTransaction]. For this purpose, ...
