[Qemu-devel] [PATCH v2 0/4]: Improve QMP visitor unit-tests

[Luiz Capitulino]

This series introduces two new test programs: test-qmp-output-visitor and
test-qmp-input-visitor.

As their names suggest, they contain unit-tests to check QMP's Visitor
implementation. They supersede the test-visitor program (which is dropped
by this series).

Besides adding new unit-tests, I've _tried_ to follow these principles:

- The tests don't print test result data to be manually checked by humans.
  Instead, all results are checked with g_assert()s and printed results
  are only OK or FAILED

- Each test-case checks a single functionality

- A test-case is only allowed to use a QAPI functionality after it has
  been tested

- setup and teardown functions are used as much as possible to avoid
  duplication

PS: The first patch is a fix unrelated to the QAPI.

[Qemu-devel] [PATCH 1/4] configure: Don't mix glib and libcheck tests

[Luiz Capitulino]

test-coroutine is listed as a libcheck test in the 'checks' variable. This
is not right because 'make check' won't run test-coroutine if libcheck
tests are not enabled (either because libcheck isn't detected or because
--disable-check-utests is passed).

Tests using the glib test framework are independent from libcheck and
afaik are always present (although having a configure switch to disable
them is probably worth it).

Untangle test-coroutine from the libcheck tests by introducing the
'test_progs' variable and using it to generate the test list used by
'make check'.
