Wait until all Task finish in unit test

Question

I have this class I want to unit test:

public class SomeClass
{
    public void Foo()
    {
        Bar();
    }

    private void Bar()
    {
        Task.F         


        

Answer 1

Task.WaitAll(the, list, of, task, objects, you, need, to, wait, on);

If it's a void async method then you can't do it. The design is broken. They're only for fire and forget.
