Functional testing with a dedicated server

I was wondering if anyone can point me in the right direction in regards to running functional test with a dedicated server. I checked out all of the documentation here Functional Testing | Unreal Engine Documentation and it seems like it is all tailored towards client based testing.

I have a multiplayer game and I wanted to set up some automated tests that would spin up a server and then load in one of my actors that uses GAS and then verify that the correct attributes loaded in. I need the test to be able to run a server and a client in order to achieve this.

Any help in the right direction would be much appreciated. I feel like automated tests are a topic most people don’t talk about

Funtional Test does not support testing with Dedicated Server. I was trying to do the same about a year ago and after some engine code debugging I found that multiplayer feature for FTs is just not implemented. Also, I found this:

Since then I came up with my own solution, which is essentially (1) extending the AFunctionalTest class to add Server-Client synchronization and (2) using Gauntlet Automation Framework to start Dedicated Server and Clients for testing.

PS: Currently, I am preparing a talk about my solution. You can watch it online here:

Thanks for the answer. This was exactly what I had to do. I’m going to bookmark the link so I can hear your talk later. Currently I had to use the Daedalic Plugin(GitHub - DaedalicEntertainment/ue4-test-automation: Facilitates setting up integration test suits with Unreal Engine 4 Gauntlet.) which I want to move away from. Would be cool to see how you directly extended it to provide those functions.

If you’re taking any requests for the talk, maybe throw in testing across multiple maps :). My current limitation with that plugin is that it will only test one map in CI/CD so I have to either run a jenkins job for each map(I have a moba so its a lot of runs since each char will get its own test map) or put them all in one map and reset the map for each character

Yes, I know about Daedalic plugin but I have never used it.

About testing across multiple maps, I’m pretty sure my solution is very similar to what you have now. I’m running a single instance of the Gauntlet which starts Server and 2 Clients on a specified map. Then, a list of Functional Tests is executed there. I named the whole process as a “Gauntlet Test”.

When I want to test on a different map, I just run another Gauntlet Test with a different configuration. I prepared a Batch script that starts all my Gauntlet Tests (currently 16) one after another on different maps.

I throw this topic into my presentation :slight_smile:

Are you willing to go into detail or share code about how you got tests running in a networked environment?

Thank you for your share, I think the content you posted is exactly what I need. But I cannot find your lecture video through this link. Could you please tell me where I can find this video now?
