6.6.0 has a potentially bad bug

Please upgrade to the latest version.

6.6.0 has a bug that can, if everything goes wrong just right, delete files in the root of the project. I only saw it happen when running the test suite for Gut and only the test_doubler.gd test script. I don't recall ever seeing it happen in my own game, but just to be safe you should upgrade.

Gut 6.7.0

GUT (Godot Unit Test) is a utility for writing tests for your Godot Engine game. It allows you to write tests for your gdscript in gdscript.

Features

• Godot 3.0 and 3.1 compatible (There are some minor issues with 3.1 though, check them out here.)
• Simple install via the Asset Library.
• Doubling
• Stubbing
• Spying
• A plethora of asserts and utility methods to help make your tests simple and concise.
• Export tests with your project and run them on any platform Godot supports.
• Command Line Interface (CLI)
• Support for Inner Test Classes to give your tests some extra context and maintainability.
• Integration testing made easier with yields

More info can be found in the wiki.

Upgrading to 6.7.0 from any 6.x version

• It is not required, but you should remove the existing Gut node for any scenes you have that use it and then re-add it and re-configure it. Re-adding will get rid of the caution symbol next to the control (this is due to changes in inheritance, Gut changed from a WindowDialog to a Control)
• For the command line, note that the log option in the .gutconfig.json file has changed to log_level for consistency.
