GD-607: GdUnit4 Godot plugin does not find test suites at the root folder

[esainane]

The used GdUnit4 version

4.4.4 (Pre Release/Master branch)

The used Godot version

v4.3.1.rc.mono.custom_build [ff9bc0422]

Operating System

6.11.5+bpo-amd64 #1 SMP PREEMPT_DYNAMIC Debian GNU/Linux trixie/sid 6.11.5-1~bpo12+1 (2024-11-11) x86_64

Describe the bug

The gdUnit4 settings description for Test Lookup Folder states:

Subfolder where test suites are located (or empty to use source folder directly)

However, leaving this setting empty (or set to /, or res://) will cause gdUnit4 to not find any test suites in the root folder. scan_test_directories starts by examining subfolders, though it is very permissive with any of these test directory settings.

This structure would be bad practice in a proper project, since it has to perform a lot of scanning which a dedicated test directory would avoid. However, this should eliminate much confusion when trying to create a minimal reproducible test project, and wondering why the test suite is silently not being detected.

This is not a problem when using the GdUnit4 Test Adapter via VSTest; tests located in the root folder will be correctly located and executed when going through VSCode. This is only an issue when going through the GdUnit4 Godot Editor plugin.

Steps to Reproduce

• Configure Test lookup folder in gdUnit4 settings to be blank (or /, or res://)
• Create a test case in the root directory of the project:

namespace GDUnit4RootTestExample;

using Godot;
using GdUnit4;

using static GdUnit4.Assertions;

[TestSuite]
public class ExampleTest
{
    [TestCase]
    public void FindMe() => AssertBool(true).IsTrue();
}

• Run tests via VSCode. Observe VSCode finding the test.
• Run tests via Godot Editor. Observe Godot Editor failing to find the same test.
