SACON NY 2019 Workshop

Requirements

• Github account
• Java 8
• IntelliJ IDEA (enterprise edition recommended but community would also work)
• [For Windows only] git bash
• [Optional] TravisCI linked to your Github account
• [Optional] Codecov linked to your Github account

Setup local environment

Go to the library-monolith directory:

cd library-monolith

To run:

$ ./gradlew bootRun

To edit with IntelliJ:

$ ./gradlew idea

$ open library-monolith.ipr

To run tests:

$ ./gradlew test

To see the coverage

$ ./gradlew check $ open build/reports/jacoco/test/html/index.html

Exercise 1: add more tests

Look at the jacoco report to understand the parts of the code that need more coverage.

Hint: Try creating a test for the method borrow in the CatalogController

You can follow a possible solution in Exercise1

or you could checkout the branch:

$ git fetch
$ git checkout 1_monolith_with_tests

Exercise 2: re-organize monolith and create clear separation of packages

The goal of these exercises is to end up with three distinct packages that express the different bounded contexts:

com.oreilly.sacon.library.availability
com.oreilly.sacon.library.catalog
com.oreilly.sacon.library.rating

Hint: Use refactoring techniques like composing methods and moving features between objects. Don't be afraid of organizing data.

You can follow a possible solution in Exercise2-part1 and Exercise2-part2

or you could checkout the branch: $ git checkout 2_monolith_with_packages
