/*************************** tests **********************************/

/*
 * This is a controller module: a plugin to ivi-shell.so, i.e. a sub-plugin.
 * This module is specially written to execute tests that target the
 * ivi_layout API.
 *
 * This module is listed in meson.build which handles
 * this module specially by loading it in ivi-shell.
 *
 * Once Weston init completes, this module launches one test program:
 * ivi-layout-test-client.ivi (ivi-layout-test-client.c).
 * That program uses the weston-test-runner
 * framework to fork and exec each TEST() in ivi-layout-test-client.c with a fresh
 * connection to the single compositor instance.
 *
 * Each TEST() in ivi-layout-test-client.c will bind to weston_test_runner global
 * interface. A TEST() will set up the client state, and issue
 * weston_test_runner.run request to execute the compositor-side of the test.
 *
 * The compositor-side parts of the tests are in this file. They are specified
 * by RUNNER_TEST() macro, where the name argument matches the name string
 * passed to weston_test_runner.run.
 *
 * A RUNNER_TEST() function simply returns when it succeeds. If it fails,
 * a fatal protocol error is sent to the client from runner_assert() or
 * runner_assert_or_return(). This module catches the test program exit
 * code and passes it out of Weston to the test harness.
 *
 * A single TEST() in ivi-layout-test-client.c may use multiple RUNNER_TEST()s to
 * achieve multiple test points over a client action sequence.
