How to associate `_test.go` with `Golang` icon

I’ve changed the icons for javascript test files like so: I would like to do the same for golang. However, the extension gets confused because _test.go is not really a file extension.

Following code shows what my settings.json config looks like now:

    "vsicons.associations.files": [
        { "icon": "asciidoc", "extensions": ["test.js"], "format": "svg", "extends":"testjs" },
        { "icon": "asciidoc", "extensions": ["_test.go"], "format": "svg", "extends":"go" },
    ],

Thanks, Ioan

Closing as resolved.

Those two attributes are used in combination to produce multiple file extensions. Again, it’s not the glob you think it is.
