I meant at the build system end. Is there a "test" directory under packages-
split under the workdir for the recipe? You can find the workdir by running:

 bitbake -e recipename | grep ^WORKDIR=

$ bitbake -e test| grep ^WORKDIR=
WORKDIR="/<home dir>/QorIQ-SDK-yocto/build_t1040rdb_release/tmp/work/ppce5500-fsl-linux/test/1.0"
Above is the output of the command. Also  I do see the same directory path being created as part of the packages-split directory
$pwd
/<home directory>/QorIQ-SDK-yocto/build_t1040rdb_release/tmp/work/ppce5500-fsl-linux/test/1.0/packages-split/<package name i.e. test>/test/test1/test2/test3

Along with that we see  rpm in deploy-rpm directory and also in tmp/deploy/rpms/ directory. When I do a rpm -qp test.rpm I can see the directory structure being created and all the files present in respective directory.

Just checking, is DISTRO or MACHINE set to "test"? Does "test" appear anywhere
in the value of OVERRIDES? You can check by running:

 bitbake -e | grep ^OVERRIDES=
$ bitbake -e | grep ^OVERRIDES=
OVERRIDES="linux:powerpc:build-linux:pn-defaultpkgname:t1:t1040:t1040rdb:qoriq-ppc:e5500:fsl-networking:class-target:forcevariable:libc-glibc"

The machine type is set to t1040rdb (as we are using Freescale processors) in local.conf file. The package test.rpm is included as part of the IMAGE_INSTAL_APPEND or in the image definition file. As we need to install it separately and not as part of rootfs. 
But still I will get the output of above command

That shouldn't matter.
The reason for asking this is due to this answer on stackoverflow (http://stackoverflow.com/a/11316251/570200) and also the mailing list of busybox says this
"The busybox rpm command is more "rpm2cpio --install" than anything else.  It 
doesn't support pre or post scripts, doesn't maintain a repository...

(http://lists.busybox.net/pipermail/busybox/2006-November/059507.html)"

Also the rpm command didn't list -e or other such option which I can see on other distribution. Below is sample output
# rpm
BusyBox v1.22.1 (2015-03-03 14:40:56 IST) multi-call binary.

Usage: rpm -i PACKAGE.rpm; rpm -qp[ildc] PACKAGE.rpm

Please note that simple echo command is also not working for which I expect to echo the output on the console during the installation process.
