Class NetcodeIntegrationTest
The default Netcode for GameObjects integration test helper class
Inheritance
NetcodeIntegrationTest
Syntax
public abstract class NetcodeIntegrationTest
Constructors
NetcodeIntegrationTest()
Declaration
public NetcodeIntegrationTest()
NetcodeIntegrationTest(NetcodeIntegrationTest.HostOrServer)
Optional Host or Server integration tests
Constructor that allows you To break tests up as a host
and a server.
Example: Decorate your child derived class with TestFixture
and then create a constructor at the child level.
Don't forget to set your constructor public, else Unity will
give you a hard to decipher error
[TestFixture(HostOrServer.Host)]
[TestFixture(HostOrServer.Server)]
public class MyChildClass : NetcodeIntegrationTest
{
public MyChildClass(HostOrServer hostOrServer) : base(hostOrServer) { }
}
Declaration
public NetcodeIntegrationTest(NetcodeIntegrationTest.HostOrServer hostOrServer)
Parameters
Fields
k_DefaultTickRate
Declaration
protected const uint k_DefaultTickRate = 30U
Field Value
m_ClientNetworkManagers
Declaration
protected NetworkManager[] m_ClientNetworkManagers
Field Value
m_CreateServerFirst
Set this to false to create the clients first.
Note: If you are using scene placed NetworkObjects or doing any form of scene testing and
get prefab hash id "soft synchronization" errors, then set this to false and run your test
again. This is a work-around until we can resolve some issues with NetworkManagerOwner and
NetworkManager.Singleton.
Declaration
protected bool m_CreateServerFirst
Field Value
m_PlayerNetworkObjects
Contains each client relative set of player NetworkObject instances
[Client Relative set of player instances][The player instance ClientId][The player instance's NetworkObject]
Example:
To get the player instance with a ClientId of 3 that was instantiated (relative) on the player instance with a ClientId of 2
m_PlayerNetworkObjects[2][3]
Declaration
protected Dictionary<ulong, Dictionary<ulong, NetworkObject>> m_PlayerNetworkObjects
Field Value
m_PlayerPrefab
Declaration
protected GameObject m_PlayerPrefab
Field Value
m_ServerNetworkManager
Declaration
protected NetworkManager m_ServerNetworkManager
Field Value
m_TargetFrameRate
Declaration
protected int m_TargetFrameRate
Field Value
m_UseHost
Declaration
Field Value
s_DefaultWaitForTick
Declaration
protected static WaitForSeconds s_DefaultWaitForTick
Field Value
s_GlobalNetworkObjects
Registered list of all NetworkObjects spawned.
Format is as follows:
[ClientId-side where this NetworkObject instance resides][NetworkObjectId][NetworkObject]
Where finding the NetworkObject with a NetworkObjectId of 10 on ClientId of 2 would be:
s_GlobalNetworkObjects[2][10]
To find the client or server player objects please see:

WaitForClientsConnectedOrTimeOut()
Declaration
protected IEnumerator WaitForClientsConnectedOrTimeOut()
Returns
WaitForClientsConnectedOrTimeOut(NetworkManager[])
Validates that all remote clients (i.e. non-server) detect they are connected
to the server and that the server reflects the appropriate number of clients
have connected or it will time out.

Name |
Description |

Returns
WaitForConditionOrTimeOut(Func<Boolean>, TimeoutHelper)
Waits for the function condition to return true or it will time out.
This will operate at the current m_ServerNetworkManager.NetworkConfig.TickRate
and allow for a unique TimeoutHelper handler (if none then it uses the default)
Notes: This provides more stability when running integration tests that could be
impacted by:
-how the integration test is being executed (i.e. in editor or in a stand alone build)
-potential platform performance issues (i.e. VM is throttled or maxed)
Note: For more complex tests, ConditionalPredicateBase and the overloaded
version of this method
Declaration
public static IEnumerator WaitForConditionOrTimeOut(Func<bool> checkForCondition, TimeoutHelper timeOutHelper = null)
Parameters
Returns
WaitForConditionOrTimeOut(IConditionalPredicate, TimeoutHelper)
This version accepts an IConditionalPredicate implementation to provide
more flexibility for checking complex conditional cases.
Declaration
public static IEnumerator WaitForConditionOrTimeOut(IConditionalPredicate conditionalPredicate, TimeoutHelper timeOutHelper = null)
Parameters
Returns
