In a previous post, I gave an overview to integration tests and documenting integration points. In this post, I will give a practical example of developing and performing integration tests with the Pester framework for PowerShell. With a data platform, especially one hosted in Azure, it’s important to test that the Azure resources in your environment have been deployed and configured correctly. After we’ve done this, we can test the integration points on the platform, confident that all the components have been deployed.
The code for performing integration tests is written in PowerShell using the Pester Framework. The tests are run through Azure DevOps pipelines and are designed to test documented integration points. The PowerShell scripts, which contain the mechanism for executing tests, rely upon receiving the actual test definitions from a metadata database.
