Questions on async and sync's unit tests

Question

Hi All
I write a API project and that have sync and async method.  
Then I also write a unit tests for them.
What I want to ask is how to write them is better ?
public abstract class ApiProxyBase
        protected async Task<T>
GetDataAsync<T>(IRestRequest restRequest, bool ignoreSslCertificateValidation
= true) where T
: ApiResponse, new()
        protected T
GetData<T>(IRestRequest restRequest, bool ignoreSslCertificateValidation
= true  where T
: ApiResponse, new();
   public class GameServerApiProxy : ApiProxyBase, IGameServerApiProxy
async Task<GetGameRedirectResponse>
GetGameRedirectAsync(GetGameRedirectRequest request) ;
    public GetGameRedirectResponse GetGameRedirect(GetGameRedirectRequest request)
    public class GameServerApiProxyTest : TestsBase
        [Test]
        public async void Can_Get_Game_RedirectUrl_Async()
            await LogIn();
            var response
= await _gameServerApiProxy.GetGameRedirectAsync(new GetGameRedirectRequest());
            response.Url.Should().NotBeNull();
            LogOut();
        [Test]
        public void Can_Get_Game_RedirectUrl()
            LogInSync();
            var response
= _gameServerApiProxy.GetGameRedirect(new GetGameRedirectRequest());
            response.Url.Should().NotBeNull();
            LogOut();

I have an
article on asynchronous unit testing. I'd say your async unit test method should be async Task and not async void. Other than that, it looks good. In particular, since your interface has both synchronous and asynchronous APIs, you should have tests for
both of them.
