I've been trying to set up Unit Testing for my project under ECS, but am hitting a brick wall at the moment. Unity version: 2019.2.0b9 Test Framework: 1.0.18 Custom NUnit: 1.0.0 Unity.Physics: preview-0.2.0 Entities: preview-0.1.0 I tried following the video from over a year ago from infallible code: to set up unit testing using a custom asmdef file, which works as far as being able to test the built-in unity code, but I cannot access any of my own code this way. I tried everything I could work out from the thread about this: https://forum.unity.com/threads/how-to-unit-test-where-is-the-unity-entities-tests-namespace.540251/ but to no avail. I already had some unit testing working for some static helper classes I have to read/process input files, but when I create a custom asmdef as is done in all the unity examples, that all breaks as it no longer access my own code base at all, and of course I can't test any of the ECS parts of my code without some setup - and this is my brick wall. I tried making specific namespaces for my code, but that didn't work. I tried looking at the Unity.Physics and Unity.Mathematics test examples, but they don't help: I simply can't reference my namespaces like they do. I tried tinkering with the manifest.json but got nowhere (and if we're being critical, this really shouldn't be required anyway). Most grateful for any help to resolve this!
