Parallel tests with Mocha and WD.js

1/ Configure your Sauce Labs credentials

First you may need to create a Sauce Labs account (Go here, there is a free plan.) and enter your credentials as in the following:

export SAUCE_USERNAME=<SAUCE_USERNAME>
export SAUCE_ACCESS_KEY=<SAUCE_ACCESS_KEY>

2/ Install tools

npm install -g mocha

3/ Install local package

In this tutorial directory (there should be a package.json file) run:

npm install

4/ Inspect the code

The browsers are configured in desireds.js
The mocha test suite is in tutorial-specs.js
The parallel runner is in parallel-mochas.js

5/ Run tests

BROWSER='chrome' mocha --reporter spec *-specs.js
BROWSER='firefox' mocha --reporter spec *-specs.js
BROWSER='explorer' mocha --reporter spec *-specs.js

Go here to view the tests.

6/ Run tests in parallel

node parallel-mochas '--reporter spec *-specs.js' chrome firefox explorer
