Currently, with my Intern setup, I'm using an unbuilt Dojo build when running my Intern tests; like, for example, a test module loads app/ProductModuleA, and ProductModuleA references and loads dojo/request. I need to have the dojo/request.js file in the appropriate directory structure in order for the module to be resolved without errors and therefore the test to be able to run. Our product code does use a built dojo.js file and our previous DOH tests were able to use this, too, without any issues--I don't understand how that worked because I don't know anything really about building Dojo.
I know I've seen snippets in various Internet forums (like here) and the Intern User Guide that Intern supports source maps, which I guess suggests it's possible to use a built dojo.js file in conjunction with running Intern, but I haven't found anything at all in detail. Insights, or pointers to documentation or examples that so far I haven't been able to find?
One of the benefits of AMD is that you don't have to do anything special to your code when switching between a built and unbuilt Dojo. The first time you load a dependency using an unbuilt Dojo, the loader requests it over the network and then caches the result. Subsequent loads use the cached dependency. The loading process works the same with a built Dojo; the main difference is that all the modules built into the built Dojo are pre-cached. The loader doesn't have to request them over the network the first time because they start out in the module cache.
For Intern to use a built Dojo, you just need to make sure you're using the built Dojo as your loader during tests. You can do this by setting the useLoader option in your Intern config.
