How to automate testing of an Outlook add-in?

Question

I have an Outlook Addin developed in C #, VSTO and having a lot of unstructured code and a very large size. every time there is a modification / update, I have to manually test it from end to end, which is very painful and time consuming. This appendix contains many rules that trigger a popup / dialog box, and the user should take some action in this regard. Is there a way / tool that can be used to automate this task?

Answer 1

I would work on adding unit tests to existing code; with unit tests to verify that everything still works after your changes, you won’t have to do your end-to-end tests often.

You can also automate your end-to-end acceptance tests using the UI Automation Interface to manage Outlook.
