Question Unable to include Unity.Entities.Tests for Unity ECS Testing

Hello,

I am consistently having problems including new assembly references in my Unit Tests. In the 2020 builds, getting Unit Testing up has been nightmarishly difficult.

This is my Tests.asmdef.

Code (csharp):

1.  
2. {
3.     "name": "Tests",
4.     "rootNamespace": "",
5.     "references": [
6.         "Unity.Entities",
7.         "Unity.Entities.Tests",
8.         "Game",
9.         "UnityEngine.TestRunner",
10.         "UnityEditor.TestRunner"
11.     ],
12.     "includePlatforms": [
13.         "Editor"
14.     ],
15.     "excludePlatforms": [],
16.     "allowUnsafeCode": true,
17.     "overrideReferences": true,
18.     "precompiledReferences": [
19.         "nunit.framework.dll"
20.     ],
21.     "autoReferenced": false,
22.     "defineConstraints": [
23.         "UNITY_INCLUDE_TESTS"
24.     ],
25.     "versionDefines": [],
26.     "noEngineReferences": false
27. }

I am strictly including Unity.Entities.Tests, but in my test script...



ECSTestsFixture cannot be found, and the assembly reference is missing.

I have tried completely rebooting Unity and .net, deleting Tests/ and obj/, toggling certain assembly features on and off. Nothing, absolutely nothing, is getting this reference in .net.

Any ideas?

 

After hours of messing with this I found the answer here:
https://forum.unity.com/threads/how-to-unit-test-where-is-the-unity-entities-tests-namespace.540251/

In manifest.json, manually append this value and allow Unity Editor to recompile.

Code (csharp):

1.  
2.   "testables" : [
3.     "com.unity.entities"
4.   ]
5.  

You will see Unity.X.dlls in the EditMode unit tester and your assembly references will magically work.

Edit: This does not seem to cause .NET to recognize the file and while it will compile, .NET will throw squiggles on everything.
