Subject: oe-selftest: crosstap: add tests for crosstap script
X-Git-Url: https://code.ossystems.io/gitweb?a=commitdiff_plain;h=ec6af78ad72d7332d52e099316595a2dab0e256d;p=openembedded-core.git

oe-selftest: crosstap: add tests for crosstap script

QA team were testing crosstap script manually. Add automated
tests and systemtap file to test that crosstap script will
instructs SystemTap to print hello world in qemu. This test
will first built core-image-minimal image with tools-profile
& ssh-server-openssh features and build systemtap-native on
the host machine. Finally this test will boot the image with qemu
and then execute crosstap script to print hello world on qemu.
