In my career as a QA focusing primarily on manual testing of web applications, I was only recently introduced to the concept of SDK testing. I was hoping some people with experience in this area could give me some examples of how SDKs are tested? I understand that automation tools are available but what might some examples of manual SDK testing look like?
I did some research and all the results seem to be concerned with API testing. I understand that APIs can be an important feature of an SDK, but is that all there is to it? Is SDK testing, in practice, API testing? Or is there more to it?
