Demo unit test using Circle-CI

archiving this as it is quite old, and more people are using github-actions

This is a demo of using Circle-CI for continuous integration.

How to run locally:

run npm test ignore the failure in codecov token

Essential components

• mocha - test runner
• nyc - code coverage report
• codecov - code coverage badge
• circle-ci - continuous integration

Note

• circle.yml - this is the file used for configuring circle-ci. configured it to use node 8.11.4 and generate code coverage artifact, then send it to codecov.io
• npm test command - this invokes nyc, mocha, and codecov library. configurations are in their corresponding yml files
• coverage report - open ./coverage/lcov-report/index.html file after running the test to view code coverage
