[PATCH 2/4] meta: implement key baserunner features

[jwang]

From: zjh <junhuix.zhang@intel.com>

Baserunner contains three features:
1. load cases from a manifest file
2. load cases from a package such as "oeqa.runtime"
3. create runner engine based on pyunit textrunner

Hi Jing, 

Thanks for your submission.

There's no commit message here, which makes this harder to review as I
have to try and work out what it's for and why we want it. 

A useful commit message would tell me why we are introducing a
baserunner framework. This may also make a useful comment in the code
itself.

Also, the patch prefix for the series should be "lib/oeqa", i.e

"[PATCH 3/4] lib/oeqa: use baserunner in oetest"

We're defaulting to Python3 in OE-Core nowadays, do you really want
Python2 here (which is the default Python on most Linux distros)

What's the purpose of overloading __getattr__() here?

This comment isn't very useful, same for other similar comments in this
series.

This would probably be better as: 
self.context = context or TestContext()

or better yet, pass TestContext() as the default param for context,
rather than None?

I think this and 1/4 should probably be squashed together?

It might be nice to handle open() failing here? If open() fails we're
trying to return an undefined instance.

There's no need for a backslash here, we can rely on Python's implied
continuation.

It's much more idiomatic to write these like:

	if not names:

> +        testloader = unittest.TestLoader()
> +        tclist = []
> +        for name in names:

variable names prefixed with an underscore are, by convention,
internal/private to the object.

Is there a case where countTestCases() might not be > 0 and _tests[] !=
[] ? i.e. can we just use an else here?

This is a funny variable, when would it not be True and why? Could we
add a comment here about what the variable is for?

Should it be an argument passed at object construction, as it's denoted
as internal by the _ prefix?

If we don't configure during __init__() when do we do it? Why might we
not do it during __init__() ?

We appear to be using a non-public instance variable, is there
something else we could be using here to get the list of tests?
