Game Testing Methodology for Engine-Based Projects

## TL;DR

Game testing works best when deterministic logic, build checks, and device automation are separated from subjective playtesting.

## Core Explanation

Engine projects have a mixed test surface. Pure gameplay rules, save/load code, economy math, and content validation can often be automated. Feel, pacing, readability, difficulty, and fun still require human playtesting and structured feedback.

For AI-assisted game development, test boundaries matter even more. An agent can draft unit tests, generate reproduction steps, or prepare a matrix, but the project should still decide which engine mode runs the test and whether the result is allowed to block a build.

## Source-Mapped Facts

- Unity Test Framework documentation distinguishes Edit Mode tests, which run in the Unity Editor, from Play Mode tests, which exercise game code at runtime. ([source](https://docs.unity.cn/Packages/[email protected]/manual/edit-mode-vs-play-mode-tests.html))
- Unity Build Automation documentation states that Unity Build Automation can run unit tests as part of the build process and supports both Edit Mode and Play Mode tests. ([source](https://docs.unity.com/en-us/build-automation/reference/unit-tests))
- Unreal Engine Automation System documentation describes the Automation tab as a way to run automation tests on connected devices or devices on a local network.
