Testing Docker container dependencies with Circle CI.

Circle CI & Docker

Testing Docker container dependencies with Circle CI.

Overview

This is a sample repo that tests out Circle CI builds when Docker container dependencies are requried. This project contains a basic node application that will attempt to access a RethinkDB server hosted within a Docker container.

Technology used

The following tech is used in this sample:

• Docker
• RethinkDB
• io.js (node)
• mocha (for testing node)
• co-mocha (async for mocha using generators)

Circle CI

Node / Mocha

In order for mocha to output results into a format that Circle CI can understand you will need to use mocha-junit-reporter, on a new project the following will get you going:

npm install mocha mocha-junit-reporter --save-dev

In addition to using the correct reporter, you will also need to ensure that the test results are sent to the correct folder ($CIRCLE_TEST_REPORTS). See the script/ci-test for the command that handles this:

MOCHA_FILE=$CIRCLE_TEST_REPORTS/test-results.xml node --harmony ./node_modules/.bin/mocha --reporter mocha-junit-reporter test/**/*.js

Scripts

The key files used in the build are as follows:

• circle.yml - this defines the
• script/ci-bootstrap - this sets up dependencies, including pulling docker containers and starting them
• script/ci-test - this kicks off the mocha test suite
