Trying out using the Azure DevOps - Create a Work Item action to create a Test Plan. The issue that I'm running into is that it doesn't seem to also create the default Test Suite that appears when created via dev.azure.com. I've also tried to create a Test Suite and link it to the Test Plan using the Hierarchy-Reverse link type, which links it in Azure DevOps, but does not seem to be the correct link type.
When a test plan is created via the web, the default test suite is created, however I cannot see how these end up linked, either through the api or through the web.
Has anyone been able to successfully create a Test Plan for Azure DevOps using this action?
