    tests: ivi_layout test infrastructure · f5b74f7d
    Pekka Paalanen authored
    Testing the ivi_layout API requires two things:
    - the tests must be written as a controller module to access the API
    - the tests need a helper client to create some objects that can then be
      managed via the API
    This patch adds all the infrastructure and two different kinds of
    example tests.
    Internal ivi-shell (ivi_layout) API tests are listed as ivi-*.la files
    in TESTS in Makefile.am. Weston-tests-env detects these, and runs Weston
    with ivi-shell, and loads the given module as a controller module, not
    as a normal plugin.
    The test controller module ivi-*.la will launch a helper client. For
    ivi-layout-test.la the helper client is ivi-layout.ivi.
    The helper client uses the weston-test-runner framework to fork and exec
    each TEST with a fresh connection to the compositor.
    The actual test is triggered by the weston_test_runner protocol
    interface, a new addition to weston-test.xml. The helper client uses
    weston_test_runner to trigger a test, and the server side of the
    interface is implemented by the test controller module
    The server side of weston_test_runner uses the same trick as
    weston-test-runner.h to gather a list of defined tests. A test is
    defined with the RUNNER_TEST macro.
    If a test defined by RUNNER_TEST succeeds, an event is sent to the
    helper client that it can continue (or exit). If a test fails, a fatal
    protocol error is sent to the helper client.
    Once the helper client has iterated over all of its tests, it signals
    the batch success/failure via process exit code. That is cought in the
    test controller module, and forwarded as Weston's exit code.
    In summary: each ivi_layout test is a combination of a client side
    helper/setup and server side actual tests.
    v2: Load weston-test.so, because create_client() needs it.
    v3: add a comment about IVI_TEST_SURFACE_ID_BASE.
    v4: Rebased to upstream weston-tests-env changes.
