As a contributor to the Nutrition Information API, I want continuous integration to automatically check ~100% code coverage for unit tests of a pull request, so I can automatically assert there have been automated unit tests written for all of the new code.

Acceptance Criteria

Given a PR, when there are new commits, then the code coverage for unit tests is automatically determined.
Given a PR, when there are new commits and code coverage for unit tests is ~100%, the PR can be merged.
Given a PR, when there are new commits and code coverage for unit tests is less than ~100%, the PR cannot be merged.

Test Plan Testing for this issue will be done manually covering the acceptance criteria by creating pull requests to match each of the criteria.

Development Plan

Use:
- mocha for testing
- chai for asserting
- istanbul for coverage metrics, coverage checks, and reporting
Create .gitignore and add:
- node_modules
- coverage
Do:
- A function to return "hello world" in index.js
- Open a Pull Request and see the checks pass
- Add a unit test that does not perform 100% coverage
- Update package.json's test script to run the unit tests
- See the open Pull Request's checks pass
- Install istanbul and update package.json's test script to generate coverage reports and ensure 100% coverage
- See the open Pull Request's checks fail
- Updated the test to do 100% coverage
- See the open Pull Request's checks pass
- Merge the Pull Request.
