Using Newtonsoft.Json in tests: "The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)"

[k7n4n5t3w4rt]

Expected behavior

I expected to "using Newtonsoft.Json" to import the package.

Actual behavior

The "using Newtonsoft" line causes a compilation error:

Assets/Tests/EditMode/DataTest.cs(6,7): error CS0246: The type or namespace name 'Newtonsoft' could not be found (are you missing a using directive or an assembly reference?)

Steps to reproduce

• New project
• Import jillejr.newtonsoft.json-for-unity via UPM
• Add following script to scene:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.TestTools;
using NUnit.Framework;
using Newtonsoft.Json;

public class DataTest
{
  [Test]
  public void JsonIsReturned(){
    var jsonString =  "{\"$base\":14}";
    var expectedInfo = JsonConvert.DeserializeObject<JiraData>(jsonString);
  }
}

• Save the file in VSCode and Unity compiles

Thanks for your package and for your time!

Ok. using Newtonsoft.Json works for scripts in /Assets/Scripts/, just not for the test scripts I've got in /Assets/Tests/EditMode. The solution might be something to do with assembly definition files.

Closing, as this seems to be a Unity thing rather than something specific to this package.

Thanks for bringing this up. Yes it seems common to have to specify all references manually for testing assembly definitions.

As said in the linked forum post you can solve it by clicking + on the references and selecting Newtonsoft.Json

[k7n4n5t3w4rt]

Oh yes. I wasn't really getting that. In the info panel for the assembly definition file in (for me) the /Assets/Tests/EditMode folder. Thanks 🙏🏻

Sometimes (depending on Unity version) disabling the "Override References" checkbox will then automatically reference it, like it does in any other asmdef.
