Running the application (using the assembled jar file)

First assemble(using sbt-assembly plugin) the application with sbt:

$ sbt assembly

or from sbt console

> assembly

sbt-assembly will execute all unit tests before packaging the application jar file with all dependencies included.

The generated jar file is placed under target/scala-2.11/Momenton - code challenge-assembly-0.1-SNAPSHOT.jar

I have renamed the jar file to app.jar for convenience

To execute the generated jar file, go to the directory where the jar file is generated:

$ scala app.jar

Running the unit tests

$ sbt test

Run test with enabled coverage

$ sbt clean coverage test

Generate the coverage reports

$ sbt coverageReport

The generated coverage reports(in HTML) can be found in target/scala-2.11/scoverage-report

Built With

Scala - Object-Oriented Meets Functional
sbt - The interactive build tool
Intellij IDE - Capable and Ergonomic IDE for JVM
