In this post, we will show you how to write some Python code to create an Airflow “job” (aka Directed Acyclic Graph or DAG) to trigger some infrastructure tests. By creating this Airflow DAG, everyone in the team that has access to Airflow can run those tests. This post is intended for testers who want to practice writing DAGs. 1. […]
Triggering Chef InSpec tests with Airflow DAG
Getting everyone to write infrastructure tests
In this post, we will outline our usual strategy to get an entire team to quickly fill testing holes – like writing infrastructure tests. Why? Because we find ourselves using this approach frequently at clients. Some context: Qxf2 engineers work with early stage products that neglected writing tests in favour of shipping quickly. This means, we almost always enter situations […]
Auditing AWS cloud resources with Chef InSpec
Continuing from the preceding blog, ‘Auditing OS Level Resources with Chef InSpec’ which delved into utilizing the Chef InSpec open-source tool for testing individual servers via OS level resources. Now, we embark into the domain of Chef InSpec’s facility in cloud environments. Chef InSpec extends its support to cloud platforms like AWS, Azure, and GCP. Referring to insights shared in […]
Auditing OS level resources with Chef InSpec
Many of Qxf2‘s clients store their Infrastructure as Code. This means that new infrastructure is spun using code and then the application is deployed. So, as testers, we now have to verify that the right infrastructure was spun up and configured correctly. In this post, I will show you how to use Chef InSpec – a tool to write tests […]
Test Lambda before deployment on CI using LocalStack
In my previous posts, I covered how to write tests for Lambdas, run them on LocalStack and addressed the issue I encountered while working on LocalStack. Now, in this post, I will show you how to set up a GitHub Action job to run tests on LocalStack before deploying Lambdas to production. At Qxf2, we place high importance on CI/CD, […]
Testing AWS Lambda locally using LocalStack and pytest
Testing loosely coupled microservices requires the use of diverse testing tools. Unlike monoliths, it is challenging to have a complete copy of the production system (System Under Test) for integration testing. Often, developers are hesitant to make changes in the pipeline due to uncertainty about potential downstream impacts. In such cases, it is valuable for developers to test integration components […]
Troubleshooting Common Issues when using Chef InSpec with GitHub Actions
At Qxf2, we have been using Infrastructure tests at our clients for a while now. We recently came up with the idea of adding some infrastructure tests for our own servers and applications within Qxf2. We used Chef Inspec to write and execute our tests. Chef InSpec is a popular open-source framework that helps you test and review your applications […]
Testing Infrastructure as Code: A beginner’s guide
This post is for testers who wants to know about testing Infrastructure as Code. We are also aiming to help testers who are looking for a change to their testing domain. I worked as a functional tester for more than 18 years in various roles. For the past one and half years, I am a tester in a DevOps team. […]
Set up a CI/CD pipeline to run lambda tests using AWS cloud service emulator named LocalStack
Recently, I have explored LocalStack AWS local stack to test cloud application locally. You can test the lambda in the AWS lambda console or Moto i.e. mocking. However running tests against LocalStack, would be good as this would not incur any cost of using AWS Services. LocalStack can be used for running any AWS service locally as well as on […]
