Logs & Artifacts

After a test run completes, open Run Details → Artifacts to browse and download its logs and files.

Engine Logs

We automatically extract logs from common game engines:

These logs are available in the run artifacts without any additional setup.

Custom Artifacts

You can have your game write files that get automatically uploaded to the run artifacts. This is useful for:

• Custom log files
• Screenshots or recordings
• Debug data or state dumps
• Crash dumps or diagnostic files

Setup

Write files to the following directory for the Windows user running the test:

%LOCALAPPDATA%\nunu.ai\artifacts\

All files in this folder will be automatically uploaded when the test completes. The folder is created and cleared at the start of each run, so write artifacts during the run.

Example (C#):

var artifactsPath = Path.Combine(
    Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData),
    "nunu.ai",
    "artifacts"
);
Directory.CreateDirectory(artifactsPath);
 
File.WriteAllText(
    Path.Combine(artifactsPath, "custom_log.txt"),
    "Your log content"
);

Subdirectories are supported and will be preserved in the uploaded artifacts.

If an artifact has the same relative path as another collected artifact, its upload name receives a numeric suffix (for example, custom_log_2.txt). Local files are not overwritten.
