Don't Mock Your Code - The Behavior is the Unit
I first started really utilizing unit testing and test-driven development while on the DataMarket team at Microsoft was slowing migrating an ASP.NET WebForms app to MVC. In a team that had no tests maintained by developers (shudder how did we develop software this long?) it was a big cultural change led by my great colleages Jon Sequiera and Dmitry Frenkel, who I am very greatful to have the experience of working with.
At the time we'd write tests for our controllers. We'd mock out all the dependencies it would need in a test and provide them. We were also using the repository pattern and testing the controller we'd mock that out. The repository pattern was really needed as we couldn't actually make a call to the database due to a lot of different reasons that basically stem from a monolithic ball of sphagetti code and abomination that was Entity Framework 1.0.
That was nice to get developers used to writing tests for their code, but there was a lot of problems with that. Views were not tested at all,
A fast and robust way to run Sauce Labs tests in Circle CI
We've been using Circle CI at Appuri for many months now and have been very happy with it. It's very simple and has a great breadth of features, namely the ability to SSH into a build to diagnose it when things get really tricky, as well as docker build services, slack integration, and lots of built-in services. After I hit a wall with PhantomJS, and needing to run our tests on multiple browsers anyways, it was time to integrate Sauce Labs to do our browser testing, which I've had great experience with on many open source projects. In those projects I used grunt-saucelabs as I am not a big fan of Karma as I like to control the HTML page the tests run on as well as the simplicity of mocha-phantomjs and just refreshing a flat file or using browser sync.
However we're using gulp and I didn't want to pull in grunt and have two build systems. Unfortunately there's no
gulp-saucelabs, which I contemplated doing (I may sometime), but I found I could simply use mocha-cloud. However, it didn't bring up the tunnel.
