The default audio backend for qemu is configured at compile time. It
generates annoying warning messages to qemu's stderr when running our
tests, like these:
pulseaudio: set_sink_input_volume() failed
pulseaudio: Reason: Invalid argument
pulseaudio: set_sink_input_mute() failed
pulseaudio: Reason: Invalid argument
Explicitly set the audio backend to "none" at runtime to remove those
messages from our logs. There is no command line argument for this, so
use an environment variable when starting qemu.

As suggested by Arnout in [1].
While at it, simplify the logic by always appending the BR2_JLEVEL and
defaulting to 0 (the value copied from Config.in is used for 5 years now
and is very unlikely to change).

Since commit cf3cd4388a the -j option is
silently ignored.
The configuration lines are processed using '\n'.join().
This function adds intervening occurrences of the separator, but the
resulting string does not end at a separator.
>>> "n".join(["a","b"])
'anb'
It results in a defconfig that does not end in a newline.
When BR2_JLEVEL is added by -j logic to the defconfig it ends up
concatenated to the last line of the defconfig.
BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_ARM=yBR2_JLEVEL=7
The resulting .config has the default BR2_JLEVEL=0.
Instead of just workaround this problem by adding a newline before
BR2_JLEVEL when -j is used, make the defconfig to end in a newline since
it is a more future-proof solution.

In commit b78b50465c, the initialisation
of BRTest.builddir was moved to the __init__ function. However, it is
set based on BRTest.outputdir and that is only set when the -o argument
is given to run-tests. When called as "run-tests -l", there is no -o
argument so BRTest.outputdir remains unset.
To fix, keep BRTest.builddir at None when BRTest.outputdir is None.
While we're at it, drop the direct access to the class member. If a
subclass wishes to set outputdir to something else before calling
BRTest.__init__, they are free to do so.

When the parameter logfile is passed to spawn(), pexpect sends both

One way to avoid the double echo in the logfile would be to disable the
echo on the terminal just after login ("stty -echo"), but double echo of
user and password would remain.
Instead of that, send only the stdout to the logfile using the
logfile_read property.

Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
This commit adds the core of a new testing infrastructure that allows to
perform runtime testing of Buildroot generated systems. This
infrastructure uses the Python unittest logic as its foundation.
This core infrastructure commit includes the following aspects:
- A base test class, called BRTest, defined in
support/testing/infra/basetest.py. This base test class inherited
from the Python provided unittest.TestCase, and must be subclassed by
all Buildroot test cases.
Its main purpose is to provide the Python unittest setUp() and
tearDown() methods. In our case, setUp() takes care of building the
Buildroot system described in the test case, and instantiate the
Emulator object in case runtime testing is needed. The tearDown()
method simply cleans things up (stop the emulator, remove the output
directory).
- A Builder class, defined in support/testing/infra/builder.py, simply
responsible for building the Buildroot system in each test case.
- An Emulator class, defined in support/testing/infra/emulator.py,
responsible for running the generated system under Qemu, allowing
each test case to run arbitrary commands inside the emulated system.
- A run-tests script, which is the entry point to start the tests.
Even though I wrote the original version of this small infrastructure, a
huge amount of rework and improvement has been done by Maxime
Hadjinlian, and squashed into this patch. So many thanks to Maxime for
cleaning up and improving my Python code!
