Introduction Testing code that depends on external services and APIs, e.g. the GitHub API, has a variety of challenges. Writing tests that make real HTTP requests to these services may be error-prone due to issues such as network connectivity, API changes, rate limiting and so on. Nock allows us to avoid these challenges by intercepting […]
The upcoming platform update is scheduled for July 26th, 2016. Bundler gets an update with version 1.12.5. Cassandra is updated to version 2.2.7.
Introduction Phoenix lends itself to rapid and productive workflows when building Elixir web services, and the Mix tool provides extensible automation of repeated tasks such as compiling code and running tests. However, containerization can be helpful when we want to build and run a release along with its supporting infrastructure. In this tutorial, we’ll learn […]
Introduction You’ve built some Docker images and made something locally. Now it’s time to go to production — and you’re stuck. This is not uncommon. There are quite a few articles out there about using Docker in a development environment. However, running Docker in production could still use a detailed explanation. This tutorial will take […]
Running code in different environments can often produce unexpected behavior. Development and testing environments strive to replicate production envrionments as closely as possible, but there’s still much to be desired. This is where containers come in. When using Docker-based deployments, environments for development, staging and production are virtually the same, and they can be rapidly […]
Note that this tutorial is no longer considered valid as it does not match our quality standards. Introduction Testing is an integral part of the software development process which helps improve the quality of the software. There are many types of testing involved like manual testing, integration testing, functional testing, load testing, unit testing, and […]
Introduction Having a large collection of unit tests that verify the behaviour of Java classes is only the first step to a sound testing strategy. After all, the fact that individual Java classes work successfully in isolation does not mean that the application itself will also work correctly ,when all these classes are bundled together. […]
Today, we’re happy to introduce a preview of Semaphore Enterprise, a new edition of Semaphore that helps large companies take advantage of our continuous integration and delivery (CI/CD) solution, while meeting their company security standards and need for advanced support and access control. We’re also proud to announce a partnership with Docker, who will make […]
As more and more developers see the benefit in delivering their apps through containers, managing Docker images is becoming increasingly important. Google Container Registry (GCR) provides a way to handle this need in a simple and secure way.
Introduction This tutorial is the fifth part of our series on test-driving an Ember.js application. In this series, we have been building a complete application using Ember.js and Ruby on Rails. The premise of our application is a digital bookcase, where we can keep track of all the books we own. If you’ve finished the […]
The upcoming platform update is scheduled for June 21st, 2016. Chromdriver gets an update with version 2.22.Elixir receives an update with version 1.2.6.
With the rapidly growing use of microservices, fast and scalable image distribution has become a critical aspect of the software development practice. If you’re using Docker for developing your applications, you’re already familiar with container registries such as Docker’s own Docker Hub. Container registries are used to store, fetch, or deploy Docker images quickly and […]
Introduction No matter in what language you’re developing, there’s likely to be a range of testing frameworks available. The same goes for Go — you can either use go test or one of the third-party packages such as Ginkgo, Goblin, and GoConvey. All of these are powerful testing frameworks to use when developing software applications […]
Docker’s increasing popularity and the move toward microservices grew the need for container registries such as the Amazon EC2 Container Registry (ECR). Cloud-based container registries provide an easy way to store, retrieve or deploy Docker images in a fast and scalable way. Amazon ECR is one of the most popular services for storing and keeping […]
Introduction Checking assumptions is important both when it comes to working with code and with finances. To build reliable software, we need to set, and then double-check our assumptions through tests. When dealing with finances, it is also important to verify assumptions and analyze transactions. Most banks offer the possibility to export data about transactions […]
