There is an issue with unit testing VS Code extensions. The
vscode dependency - which is needed to utilise the editor’s features - will error when running unit tests. Essentially it is a third party dependency which is out of your control, so the best thing to do is to mock the API. I will be using Jest and will explain how to use its mocking features to handle the VS Code dependency.
For most of my published open source projects I’ve added a simple continuous integration (CI) pipeline using Travis CI. This time around I wanted a way to deploy a project after successful integration and try a new pipeline. Azure DevOps caught my attention. The goal here is to build, test and deploy my VS Code extension Git Mob to the marketplace.
I’ll provide bite size instructions to help you build a CI and continuous delivery (CD) pipeline for your VS Code extension on Azure DevOps platform. Following these steps I estimate it will take 15-25mins to get it all working.
This post is to help developers who are new to Azure DevOps releases and deploying a VS Code extension. Azure pipelines come with lots of great options but it can be difficult to know what to do to achieve your goal. The goal in this case is to deploy my VS Code extension, Git Mob to the marketplace.
I’ll provide bite size instructions to help you build a release for your VS Code extension using Azure DevOps platform. This will take about 5-10mins.
