Why don't we want to run the after suspend tests?

IIRC, the snap interfaces are initialized when the snap is installed, so we should be safe to ignore those tests in Post-suspend stage.

I don't get it. What will happen if we test them after suspend?

I mean the snap interfaces are initialized when it is installed. Thus, the interface will not be affected during the suspend and resume process (unlike the kernel driver, which may experience changes or need reinitialization) . So we don't need to have the after-suspend tests.
