[Avocado-devel] Multiplex and avocado-vt

[Cleber Rosa]

Hi Olav,

Avocado-vt tests, by default, do not use the parameters from the multiplex. By default, is parameters come from the precursor of the multiplexer (known as the cartesian config file).

But, Avocado actually sends the parameters over, and there's a way to actually use them from within avocado-vt tests. The syntax (from within a test) is:

   sleep_length = self.avocado_params.get('sleep_length', default=1)

The parameter 'sleep_length' is a parameter that should come from the multiplexer.

About Avocado-virt: this is where a more native (and pleasant) experience should be found. Unfortunately, it's still far from the same level of features and tests as Avocado-vt. But, Avocado-virt should receive most of our development energy from now on.

If you feel that Avocado-virt better suits your needs, great! Let's work together on that!

BTW, a few pointers on Avocado-vt + multiplexer:

 - https://github.com/avocado-framework/avocado-vt/blob/master/avocado/core/plugins/vt.py#L254
 - https://github.com/avocado-framework/avocado-vt/blob/master/avocado/core/plugins/vt.py#L321


Thanks,
CR.
