RFC PATCH: Issue 90 (Test Clarification)

[Ryan Gahagan]

We addressed the feedback from our previous RFC patch for the most part.
Under src/util/virstoragefile.c, we left a cast to an integer pointer
that Peter mentioned because we were unable to provide a better
solution. We've written some tests for our code but our testing
environment is not working locally (meson doesn't even recognize the
project as a meson build project) and so we can't regenerate output or
test our tests.

It's probably bad practice but the only solution we could think of that
would allow us to check our tests was just to email you what we've got.
Sorry if it's not up to standard, but please let us know if there's a
better way to do it or if you spot any problems in these tests.

Under tests/qemuxml2xmltest.c:
DO_TEST_CAPS_LATEST("disk-network-nfs");

The same line would be in tests/qemuxml2argvtest.c

We created the file tests/qemuxml2argvdata/disk-network-nfs.xml:
<domain type='qemu'>
  <name>QEMUGuest1</name>

      <source protocol='nfs' name='/foo/bar/baz'>
        <host name='example.com' port='2049'/>
        <nfs user='nfs-user' group='nfs-group'/>
      </source>
      <target dev='vda' bus='virtio'/>
      <serial>eb90327c-8302-4725-9e1b-4e85ed4dc251</serial>

    </disk>
    <controller type='usb' index='0'/>
    <controller type='pci' index='0' model='pci-root'/>
    <input type='mouse' bus='ps2'/>
    <input type='keyboard' bus='ps2'/>
    <memballoon model='none'/>
  </devices>
</domain>

We have under tests/qemublocktest.c:
TEST_JSON_FORMAT_NET(“<source protocol=’nfs’ name=’/foo/bar/baz’>\n”
                     “  <host name=’example.com’ port=’2049’/>\n”
                     “  <nfs user=’USER’ group=’GROUP’/>\n”
                     "</source>\n”);
and
TEST_IMAGE_CREATE(“network-nfs-qcow2”, NULL);

And finally under tests/virstoragetest.c:
TEST_BACKING_PARSE(“json:{\”file\”:{\”driver\”:\”nfs\”,”
                                   “\”user\”:\”USER\”,”
                                   “\”group\”:\”GROUP\”,”
                                   “\”server\”: {  \”host\”:\”example.com\”,”
                                                  “\”port\”:\”2049\””
                                               ”}”
                                  “}”
                        “}”,
                   “<source protocol=’nfs’ name=’/foo/bar/baz’>\n”
                   “  <host name=’example.com’ port=’2049’/>\n”
                   “  <nfs user=’USER’ group=’GROUP’/>\n”
                   “</source>\n”);

Again, sorry if this looks awful. Please let us know if there's a more
practical way to do this because submitting a commit with these tests
would guarantee that the tests fail and the commit wouldn't be mergeable
due to our environment issues, or if you see anything wrong with these
tests.
