Why is this removal needed? Having package.name can ensure the test runs only when that package is available (for instance, when running using a virtual environment).

@pieqq It is not working on the snap version of checkbox, since we package rt-tests into the stage-packages, it is not going to be shown in the resource job package, due to the fact that package only list the debian package installed on the local.

Please use snap resource job instead if this is a snap package to be checked

That, or the executable resource.
