Over the past week we rolled out an update to our repository caching system. Previously cache was branch based, and all users suffered one disadvantage: first builds of every new branch took more time as the git clone and bundle install had to be done from scratch.

Semaphore is great for testing your web application. Every day, code of thousands of developers is flowing through Semaphore for verification so that they can deliver new features to users with confidence.

All Ruby developers are probably familiar with Capybara – the tool for interacting with web pages that we all use and love. A similar thing exists in the JavaScript world – CasperJS.

Growing object-oriented software, guided by tests was published in 2010 and is already considered a classic in the TDD community. I have found this to be for a good reason. It is the first book that I am aware of that guides you through development of a non-trivial application using TDD as a paradigm.

This Sunday (July 7th) we will roll out an update to our build platform. It will include the latest versions of Ruby, Node.js and a few other packages.

Pusher is a great service for sending messages from anywhere to your users’ web browsers. It has all the good features of a cloud service: reliable uptime, great customer service and it enables you to outsource a complicated but probably not critical part of infrastructure.

If you are writing JavaScript or CoffeeScript and want to practice TDD, probably the best option for you to implement automatic tests is Jasmine. There are a few nice articles to get you started with the framework (like How do I Jasmine: a tutorial and Testing Your JavaScript with Jasmine) and even a book JavaScript […]

The Semaphore add-on for Heroku is officially out of beta. The add-on makes it easy to set up continuous integration (shhh and soon deployment) for your Heroku-hosted Ruby app.

Sometimes you just want to follow a single project. Or you’d like to catch up and see what’s been happenning. Who’s been busy? Who broke the build and when was it fixed?

Here’s a quick roundup of 3rd party tools that let you get more out of Semaphore.

Our great customers from Cloud Castle have created a nice gem called cucumber_in_groups. If you follow the simple instructions, you’ll be able to parallelize your Cucumber test suite on Semaphore with just the following build commands:

When we launched Semaphore, the market for continuous integration services was ripe for change. Existing solutions were excessively complicated. Emerging hosted solutions offered, in our opinion, a poor user experience at needlessly high prices.

We have added two new endpoints to our API which allow users to get more information about a build.

Welcome to the Semaphore blog! We’ve realized that it’s time to separate from the Rendered Text blog, where we’ll continue to share other news and engineering stories from the company.
