Thomas Petazzoni March 5, 2017, 3:03 p.m. UTC 
This commit adds a few Buildroot "core" tests, testing functionalities
such as:

 - post-build and post-image scripts
 - root filesystem overlays
 - timezone support

I won't be commenting on the Python code, because I'm no Python
expert... ;-)

Yet, a few questions below...

What are those two binary blobs for?
Why are they binary blobs?
Can't they be generated locally?

This is ugly, and I guess it will be hard to maintain consistency
between this list and the checks done in the code.

This does not work well if there are any problematice character in
there, so I'd at least quote the variables.

But I would even go further and print key-value pairs to the file:

    #!/bin/sh
    printf "what='%s'\n" "${1}"
    printf "arg2='%s'\n" "${2}"
    printf "arg3='%s'\n" "${2}"
    printf "TARGET_DIR='%s'\n" "${TARGET_DIR}"
    printf "BUILD_DIR='%s'\n" "${BUILD_DIR}"
    [...]

And then use a parser [*] to read that file and store the values in an
associative array (aka dictionnary) in the python code, then you can do
things like:

    self.assert(post_log["what"], os.path.join(self.builddir, what))
    self.assert(post_log["TARGET_DIR"], os.path.join(self.builddir, "target"))

and so on... Which is much more readable IMHO...

[*] I don't know which parser, but probably one that can read key-value
pairs from a file... ;-)  Python experts may help you here... ;-]

See above.

They are just here to avoid some files containing random stuff, we
don't care what they contain. So indeed, they could be generated
instead of stored in the repository.

However, right now, the testing infrastructure doesn't allow a test to
run some custom operations *before* the build is started. But it's
clearly something that will be needed for a significant number of
tests, so we definitely want to add something like that.

I wouldn't call it "ugly", but it indeed could be better.

Not sure which parser to use here. Perhaps some sort of CSV file is
easier to parse in Python.
