The CircleCI Insights dashboard was designed to help you improve your delivery efficiency. We launched the dashboard a year ago to provide teams with actionable data for optimizing your pipelines. Since then, we’ve been listening to your feedback. By far, the most requested functionality is the ability to gain further visibility into test performance.

For the latest full-stack applications to work, a backend service is required. That is especially true when the frontend service depends on the backend service to render data. In many cases, it can be difficult to replicate the setup of the backend services so that you can test the application. This tutorial will show you how to mock HTTP requests from an API so that you can test endpoints without actually calling them in your tests. This tutorial covers these topics.

Retrospectives are a well-established resource in the software and systems engineering toolbox. From sprint retros through to post-incident reviews, we look back on our work to learn from it and to get better. We can apply the same ideas to our professional practice with a personal retrospective: writing an analysis of our experiences to learn as much as possible. We could look over a whole year of work, or focus more closely on a particular project.

When you sign a contract, you expect both parties to hold their end of the bargain. The same can be true for testing applications. Contract testing is a way to make sure that services can communicate with each other and that the data shared between the services is consistent with a specified set of rules. In this post, I will guide you through using Joi as a library to create API contracts for services consuming an API.

The introduction of Git as a source-code management system in 2005 fundamentally transformed the process of software development. Git allows developers to maintain a history of changes, or commits, to their code and revert to previous commits in seconds if something goes wrong. It makes collaboration easier by allowing branching to keep code for different features separate and seamlessly merging commits by various people.

When running a cloud service, it’s never good for customers to be the first people noticing an issue. It happened to our customers over the course of a few months, and we began to accumulate a series of reports of unpredictable start-up times for Docker jobs. At first the reports were rare, but the frequency began to increase. Jobs with high parallelism were disproportionately represented in the reports.

For the past five years, CircleCI has hired third-party penetration testing firms that hammer our product releases or infrastructure at minimum every 90 days. To date, we’ve done more than 25 of these. Sometimes they cover new product features and other times they cover infrastructure.

I’ve been leading software teams for more than 20 years and one thing I’ve learned about metrics is that leaders tend to put too much emphasis on engineering metrics alone, without considering the bigger picture. After speaking to a range of engineering industry leaders, and poring over millions of jobs processed from software teams worldwide, we found that the most insightful and relevant metrics fall into three categories: What metrics are meaningful for your team to measure?

Here’s a common situation that plagues many development teams. You run an application through your CI/CD pipeline and all of the tests pass, which is great. But when you deploy it to a live target environment the application just does not function as expected. You can’t always predict what will happen when your application is pushed live. The solution?

It’s often necessary to inject secrets into your build or deployment process so that the deployed service can interact with other services. This can be straightforward if you’re only deploying to a single environment. When deploying to multiple environments, though, you might need to dynamically inject different secrets depending on the environment to which you’re deploying.

DevOps is a growing trend, but where did it come from? It's the unification of two traditionally disparate worlds into one cohesive cycle. But it's not some recent invention or fad; it's the result of years of iteration, as engineers have cracked risk into progressively smaller chunks. In this whitepaper, we'll discuss.
