08 Jan 2019 testcontainer library to programmatically provision integration tests in Go with containers

Provisioning the environment for integration tests is not easy. You need a flexible strategy to build isolated environment per test and to inject the data you need to verify your assertions. I have ported a popular library from Java to Golang called testcontainers. It wraps the Docker API in order to provide a simple test friendly library that you can use to run containers in test cases.

31 Dec 2018 Infrastructure as (real) code

Infrastructure as code today is wrong. Tools like Chef, Helm, Salt, Ansible uses a template engine to make YAML or JSON way to smarter, but comparing this solution with a proper coding language you always miss something. GitOps forces you to stick your infrastructure code in a git repository this is good. But infrastructure as code is way more.

04 Apr 2018 Observability according to me

Prometheus, InfluxDB, TimescaleDB, Cassandra and all the time series databases that show up every week is a clear sign that now we need more than just a way to store metrics. I think is now clear that collecting more metrics is the point. More data is not directly related to a deeper understanding of our system.

29 Mar 2018 I don't give a shit about testing

This is all about how I approach testing in development. TDD, DDD, unit test, integration test. It should make my development faster and my code easy to maintain. We have a lot of different techniques because we need to be good on picking the right one.

With this article I share something about what tracing is and my experience with opentracing and opencensus.

09 Feb 2018 The right balance

My daily job as a developer is to find the right balance about everything. I would like to share what I think about this topic because the decisions that you take writing a system are the result of the software itself. So you should care about them.
