ci-tdd-java-template

A little template used for explaining CI and TDD

Introduction

This project is suppose to be used as a helper project when demonstrating and explaining continuous integration (CI), code coverage and test driven development (TDD).

The project uses Travis CI for building and the combination of Jacoco and CodeCov for code coverage. All master branch merges must go through a pull request (PR) and each PR has multiple status checks.

The status checks required are the following:

  1. Successful build from Travis CI
  2. 100% code coverage, reported from CodeCov

Assignment

The goal with this assignment is to create PR from the develop branch of a forked repository, to the master branch of the main repository where all the status checks are approved.

In order to do that, the following tasks are required.

  • Fork the repository
  • Checkout the develop branch
  • Do the coding task

Coding

The coding task is very simple but should give a good feeling of the difference between test driven development and regular unit testing. The coding task consists of implementing one method which already has unit tests, write unit tests for an already implemented method and finally implement both the method and write unit tests for one method.

Note that for the final implementation part, you can choose if you want to write the test first or the functionality.

The implementation part should be done in this order:

  1. Implement StringUtils.isPalindrome(final String str)
  2. Implement the tests for Calculator.sumAll(final Integer... valuesPram)
  3. Implement both the tests and the functionality for StringUtils.isBlank(final String str)
