Steps to create .NET class for Custom Test Type:
In Visual Studio, right-click on Reference, select Add Reference, select the DLL tab, browse to the local client folder, and select these files:.
These files are in the local ALM client folder created when you access ALM. For example, C:\Users\my_user_name\AppData\Local\HP\ALM-Client\myALMserver.
When you reference OTAClient.dll, a file, Interop.TDAPIOLELib.dll, is generated as a COM wrapper. Include Interop.TDAPIOLELib.dll in the deployment of your test type.
