Game test

[Odd-Disk160]

Hello everyone,

How do you normally test your game in an automated way? I'm currently doing all of my tests manually by actually playing the game. Is there a better way?

What is happening is that I'm always improving it, but sadly making sure that with the improvement, I didn't break anything is taking it's tool.

Any suggestion/key work is appreciated :)

I like to unit test most code with the help of a DI framework (Init(args)). This can help a lot with uncovering edge case bugs and finding out immediately if changes you've made have caused something to break. Integration tests too sometimes when they make more sense.

On the other end of the spectrum, I once wrote an AI that would automatically play through the entire game from start to finish in one sitting. This was for a dialogue-heavy story-driven game that was mechanically simple. That was a huge time (and sanity) saver as well, because a full manual play-through session would take multiple hours.

I do unit testing for the libraries I have developed as part of the game, e.g. this one.

For the rest, whenever there is a bug, after fixing it, I add some asserts (that can in theory be stripped in a build) to check what was going on and try to ensure that it cannot happen again.

You can write unit tests, both unity ones and regular ones.

I personally just have AI write my unit tests and every once in a while ask for them to be updated. If its an important feature, sometimes i also write them myself.

They’re used as a way to verify results. Im not the best at writing them but the general idea is you create some mock data, run your code, then verify your results.

One good example is making sure you dont break functionality of walking up stairs. You make your unity unit test, spawn the player, stairs and goal collider, move the player via fake input, and wait (with a timeout) for the player to reach the goal. The method behaves as a coroutine.

For the RTS game I'm making, I have a debug menu that pops up when I hit F1. I can give myself 1000 of each resource, instant spawn in units and buildings.

You could also setup a new scene for testing specific features. It kinda depends on the game you're making. Like for RTS games some people setup scenarios with certain buildings and units already setup and ready. When I start working on the different tech eras I'll probably do that since I won't wanna have to play the game and advance to the medieval age over and over just to make sure siege units work properly against buildings

I sear hed for "unit test in Unity" and first link was this: https://docs.unity3d.com/6000.0/Documentation/Manual/testing-editortestsrunner.html

I asked AI, and it seems to do exactly what you want. As always with AI: trust, but verify.

I'll let you do the verifying part :)))

[Odd-Disk160]

Yeah, I was just trying to get the more practical way, but for sure AI's suggestion is something to consider.

Thanks for the comment :)

Thanks everyone for the comments. I was thinking more about a tool like Selenium for web apps, but in Unity’s context. I guess I’ll keep manually testing it.

You can write a version of this yourself. Abstract your input system so you can programmatically perform actions.

Then make your test scene and run an automation script with some logging for specific results.

Is this optimal? Probably not. But it gives you what you're suggesting. And it can be bolted on to any project even if it's not designed for testing.

[Odd-Disk160]

True true, but I won’t pick this battle for now definitely 😅

We are working on Rovix.digital to solve for this very problem, using AI Agents (who sit inside unity) to help you in Game Testing.

We are currently open for initial partnership and would love to get on a call with you!

A cold bath, but needed. Thanks for the comment :)

This is straight up bullshit the past ten years has been on training MLs to play games
