That way, your code runs once when needed, rather than dozens/hundreds of times per frame.

Any value you set through the editor will be saved with the scene.

Any value you set through the editor will be saved with the scene, and applied to your scripts after they're created, before Awake() is called.

public class Script2 : MonoBehaviour {
    Script1 otherScript;
    void Awake() {
        //If on same object:
        otherScript = this.GetComponent<Script1>();

        //If on object "_OtherObj"...
        //Will complaing if _OtherObj doesn't exist
        otherScript = GameObject.Find("_OtherObj").GetComponent<Script1>();

        //In either case, check it worked...

        if(otherScript == null) {Debug.LogWarning("Couldn't find otherScript");}
    }

    Void Start() {
        otherScript.status = "First test";
        otherScript.Test();
        otherScript.status = "Second test";
        otherScript.Test();
    }
}

Any script variables you make public (like status) above will be surfaced in the Unity editor's Inspector when you select the object.

    Script1 otherScript;

        //Will complaing if _OtherObj doesn't exist
        otherScript = GameObject.Find("_OtherObj").GetComponent<Script1>();

        //In either case, check it worked...
