Fatal error in Unity CIL Linker when using ZenjectTestFramework and stripping is enabled - Failed to resolve assembly : NUnit

[MatthieuG9]

Describe the bug Unity linker fail when building a project that use ZenjectTestFramework in project and stripping is enabled.

Building Library\Bee\artifacts\WinPlayerBuildProgram\ManagedStripped failed with output:

To Reproduce Download the attached project and build OR :

• Create a project
• Add an assembly for the game scripts with one script
• Add a test assembly (play mode) with a SceneTestFixture. The test assembly should reference the game assembly.

Extenject and Unity info (please complete the following information):

• Zenject version: 9.3.1
• Unity version: 2022.2.2f1 or 2022.2.3f1
• Project's scripting backend : Mono with stripping or IL2CPP

Additional context The issue disappear when stripping is disabled. The error occure with any stripping level.

Workaround I forked the repo and changed TestFramework asmdef to only build on editor : https://github.com/MatthieuG9/Extenject/blob/FixAssemblies/UnityProject/Assets/Plugins/Zenject/Source/Editor/TestFramework/Zenject-TestFramework.asmdef
