[Qemu-devel] [PULL 06/19] tests/acceptance: look for target architecture in test tags first |

From: Cleber Rosa <address@hidden>
A test can, optionally, be tagged for one or many architectures. If a
test has been tagged for a single architecture, there's a high chance
that the test won't run on other architectures. This changes the
default order of choosing a default target architecture to use based
on the 'arch' tag value first.
The precedence order is for choosing a QEMU binary to use for a test
is now:
* qemu_bin parameter
* arch parameter
* arch tag value (for example, x86_64 if ":avocado: tags=arch:x86_64
is used)
This means that if one runs:
$ avocado run -p qemu_bin=/usr/bin/qemu-system-x86_64 test.py
No arch parameter or tag will influence the selection of the QEMU
target binary. If one runs:
$ avocado run -p arch=ppc64 test.py
The target binary selection mechanism will attempt to find a binary
such as "ppc64-softmmu/qemu-system-ppc64". And finally, if one runs
a test that is tagged (in its docstring) with "arch:aarch64":
$ avocado run aarch64.py
The target binary selection mechanism will attempt to find a binary
such as "aarch64-softmmu/qemu-system-aarch64".
At this time, no provision is made to cancel the execution of tests if
the arch parameter given (manually) does not match the test "arch"
tag, but it may be a useful default behavior to be added in the
future.
