%apptest doesn't seem to be working properly

[GodloveD]

Version of Singularity:

2.4.2-development.g7e33029

Expected behavior

Write this in def file:

%apptest foo
    echo "bar"

Create this file in container:

/scif/apps/foo/scif/test.sh

Actual behavior

/scif/apps/foo/scif/test.sh is not created.

Steps to reproduce behavior

$ cat > somedeffile << EOF
BootStrap: docker
From: busybox
%apptest foo
    echo 'I am foo'
EOF

$ sudo singularity build someimage somedeffile

$ singularity exec bb.simg ls -l /scif/apps/foo/scif/
