How can I check the public member access method

So I have something like that

private List<ConcurrentQueue<int>> listOfQueues = new List<ConcurrentQueue<int>>()
public void InsertInt(int id, int value)
{
    listOfQueues[id].Enqueue(value);
}

Isn't it that I shouldn't be unit testing?
If so, how can I test the InsertInt method without using any other methods? can I use the method to retrieve data from the queue to check if it was entered correctly? For this, should I use mocks?

// Sample with Queue instead of ConcurrentQueue
private void TestInsertInt(int id, int value)
{
    myInstance.InsertInt(id, value);

    FieldInfo field = myInstance.GetType().GetField("listOfQueues", BindingFlags.NonPublic | BindingFlags.Instance);
    List<Queue<int>> listOfQueues = field.GetValue(myInstance) as List<Queue<int>>;
    int lastInserted = listOfQueues[id].Last();

    Assert.AreEqual(lastInserted, value);
}

Another hack is using PrivateObject .

Personally, I would either use DI (Injection Dependency) or do privateit internalfor Unit Testing!
