Semaphore Uncut: Customizable CI/CD Dashboards

In last week’s episode of Semaphore Uncut, our co-founder Darko showed you how to auto-promote continuous delivery pipelines in Semaphore 2.0. This week, you’ll see how to set up, use and customize CI/CD dashboards in Semaphore 2.0.

Performance and Usability as Top Priorities: Interview with Slim.js Creator

In the Developer Interview series, we talk to engineers who use Semaphore and pick their brains about how they work, what wisdom they would like to pass on, and the most challenging problems they’ve faced during developing. This month we had a chat with Avichay Eyal, the man behind Slim.js – the fastest open source web-components library around.

Semaphore Uncut: Auto-promotion of Continuous Delivery Pipelines

Last week, we shared the first episode Semaphore Uncut, in which our co-founder Darko Fabijan showed you around Semaphore 2.0. In this week’s episode, you’ll learn how to automatically promote continuous delivery pipelines in Semaphore 2.0.

Semaphore Uncut: A First Look at Semaphore 2.0

We’re excited to let you know that this week we started making Semaphore Uncut, a weekly live video stream in which we will talk about Semaphore 2.0, our new continuous integration and delivery (CI/CD) product, as well as other topics relevant to Semaphore users with everyone interested to join us live.

Continuous Delivery Patterns with Serverless Applications

Adoption of serverless technology is surely growing, with emerging product companies who built on top of it. One of them is CloudZero, a Semaphore customer, who recently wrote a detailed article about their experience in achieving continuous delivery for their all-serverless system.

Semaphore 2.0 closed beta is now available. Make sure to get on the list for an early invite.

A Practical Guide to Test Doubles in Elixir

Introduction In this tutorial, we’ll be looking at one of the main use cases for test doubles in Elixir: aiding in the interaction between domain logic and impure components that exist over the boundaries of an application. Tests relying on such components are usually brittle, and need to reach out to external resources whose state may be foreign and unpredictable, thereby causing slowness and sometimes making tests fail unexpectedly. Classic…

Rails Testing Handbook Available for Kindle

In April, we officially released Rails Testing Handbook, a free ebook in which our engineers shared how to write tests and practice BDD to develop sustainable Rails applications. The handbook teaches you all you need to know about the BDD approach of analyzing, testing, coding, and designing a system in one short feedback loop. BDD helps us produce better software, while also avoiding mistakes and wasteful work. You can now…

Continuous Integration with Docker Gets More Space with New Semaphore Platform

Today we’re happy to announce general availability of the Docker Light platform. Based on Ubuntu 16.04 LTS, the environment provides one physical CPU (2 vCPUs), 4GB of RAM and 10GB of disk space.

Doubled Free CI/CD Capacity for Open Source

At Semaphore, for years we’ve been happy to support open source projects with a free continuous integration service. Today we’re increasing the free CI/CD capacity on all open source organizations from 2 to 4 Boxes.

Faster Rails CI with Automated Parallel Testing Available to All

Earlier, we launched Semaphore Boosters, a feature that allows you to automate parallelizing your RSpec and Cucumber tests in a few clicks. The feature has helped many teams to reduce their Rails CI build times by as much as 2 hours in some cases. Initially, the feature was available only to some users. It has now matured with the help of our users, and due to high interest we’ve decided…

Setting up a BDD Stack on a Rails 5 Application

This post is adapted from Rails Testing Handbook, a free ebook on building sustainable Rails apps with BDD. In this tutorial, we will guide you through the process of generating a new Rails 5 application, with all the necessary tools to set up a behavior-driven development (BDD) flow. We will set up 5 tools that represent the base of BDD development in Rails: RSpec for writing unit test, Cucumber for…

Running Applications on a Docker Swarm Mode Cluster

Introduction This tutorial is the last in a series of tutorials concerning the container orchestration tool, Docker Swarm. In this series, we’ve already seen how to establish a Swarm cluster, schedule services to the cluster’s nodes, make those services consumable from within and outside the cluster, and update and rollback services in-flight. We’ve mainly focused on the theory associated with a Swarm cluster, so in this final tutorial, we’ll get…

Lies, Damn Lies, and the State of Testing in Rails

Ruby on Rails was the first major web framework to include automated tests as part of every new project. The effects have been enormously positive. Many developers have learned to write tests well, which in turn helped them get better at design. Experienced developers were drawn by Rails’ focus on productivity and beautiful code. Their community activities have helped push the craft of web development forward. Over the years positive…
