I'm after some advice regarding a project I am currently working on. There is a front-end, similar to what Amazon is like in that sales are fed through the site(there is no API for doing this). However, the requirement I have is to test the microservices that sit behind the UI which go off to various warehouse management systems.
The issue I have is that in order to test each of these services it's dependent on data being passed through from the UI. Obviously it's fine to do this, but each of these tests will take a while to run; what I'm interested in is more of the integration behind each of these micro-services, rather than having to worry too much about the API. Does anyone have any advice about how I could go about this?
