Requirements

To run these tests, first get the vagrant setup for the systemvm working, see ../../tools/vagrant/systemvm.

Then, install dependencies

pip install nose paramiko python-vagrant envassert cuisine fabric

Running tests

Then run the tests using your favorite python unittest runner

nosetests-2.7

If you have already started the systemvm with 'vagrant up', that VM will get used for all the tests.

If you have not started the systemvm yet, it will be started and stopped for every test case. That's nice for test isolation, but it's very slow, so it is not recommended.

You can also run these tests out of the box with PyDev or PyCharm or whatever.

Adding tests

Simply create new test_xxx.py files with test cases that extend from SystemVMTestCase.

Use envassert checks to define your test assertions.

Use cuisine, fab, or paramiko to otherwise interact with the systemvm. When you do, please consider creating your own little wrappers around fab run. I.e. the pattern is

from __future__ import with_statement
from fabric.api import run, hide

def something_to_do(argument):
    with hide("everything"):
        result = run("do something %s" % argument).wrangle()
        return "expected" in result

for a new kind of check and then in your test

class HelloSystemVMTestCase(SystemVMTestCase):
    @attr(tags=["systemvm"], required_hardware="true")
    def test_something(self):
        assert something_to_do('foo')
