      <doc xml:space="preserve">#GstHarness is meant to make writing unit test for GStreamer much easier.
It can be thought of as a way of treating a #GstElement as a black box,
deterministically feeding it data, and controlling what data it outputs.

The basic structure of #GstHarness is two "floating" #GstPads that connect
to the harnessed #GstElement src and sink #GstPads like so:

|[
          __________________________
 _____   |  _____            _____  |   _____
|     |  | |     |          |     | |  |     |
| src |--+-| sink|  Element | src |-+--| sink|
|_____|  | |_____|          |_____| |  |_____|
         |__________________________|

]|

With this, you can now simulate any environment the #GstElement might find
itself in. By specifying the #GstCaps of the harness #GstPads, using
functions like gst_harness_set_src_caps() or gst_harness_set_sink_caps_str(),
you can test how the #GstElement interacts with different caps sets.

Your harnessed #GstElement can of course also be a bin, and using
gst_harness_new_parse() supporting standard gst-launch syntax, you can
easily test a whole pipeline instead of just one element.

You can then go on to push #GstBuffers and #GstEvents on to the srcpad,
using functions like gst_harness_push() and gst_harness_push_event(), and
then pull them out to examine them with gst_harness_pull() and
gst_harness_pull_event().

## A simple buffer-in buffer-out example

|[&lt;!-- language="C" --&gt;
  #include &lt;gst/gst.h&gt;
  #include &lt;gst/check/gstharness.h&gt;
  GstHarness *h;
  GstBuffer *in_buf;
  GstBuffer *out_buf;

  // attach the harness to the src and sink pad of GstQueue
  h = gst_harness_new ("queue");

  // we must specify a caps before pushing buffers
  gst_harness_set_src_caps_str (h, "mycaps");

  // create a buffer of size 42
  in_buf = gst_harness_create_buffer (h, 42);

  // push the buffer into the queue
  gst_harness_push (h, in_buf);

  // pull the buffer from the queue
  out_buf = gst_harness_pull (h);

  // validate the buffer in is the same as buffer out
  fail_unless (in_buf == out_buf);

  // cleanup
  gst_buffer_unref (out_buf);
  gst_harness_teardown (h);

  ]|

Another main feature of the #GstHarness is its integration with the
#GstTestClock. Operating the #GstTestClock can be very challenging, but
#GstHarness simplifies some of the most desired actions a lot, like wanting
to manually advance the clock while at the same time releasing a #GstClockID
that is waiting, with functions like gst_harness_crank_single_clock_wait().

#GstHarness also supports sub-harnesses, as a way of generating and
validating data. A sub-harness is another #GstHarness that is managed by
the "parent" harness, and can either be created by using the standard
gst_harness_new type functions directly on the (GstHarness *)-&gt;src_harness,
or using the much more convenient gst_harness_add_src() or
gst_harness_add_sink_parse(). If you have a decoder-element you want to test,
(like vp8dec) it can be very useful to add a src-harness with both a
src-element (videotestsrc) and an encoder (vp8enc) to feed the decoder data
with different configurations, by simply doing:

|[&lt;!-- language="C" --&gt;
  GstHarness * h = gst_harness_new (h, "vp8dec");
  gst_harness_add_src_parse (h, "videotestsrc is-live=1 ! vp8enc", TRUE);
]|

and then feeding it data with:

|[&lt;!-- language="C" --&gt;
gst_harness_push_from_src (h);

If forwarding is disabled, the user will have to either manually push
these events from the src-harness using gst_harness_src_push_event(), or
create and push them manually. While this will allow full control and
inspection of these events, for the most cases having forwarding enabled
will be sufficient when writing a test where the src-harness' main function
is providing data for the main-harness.

Forwarding is enabled by default.

gst_harness_push_from_src, this variant allows you to specify how many cranks

of data at the same time, as well as cases when one crank does not equal one
buffer to push and v.v.

      <doc xml:space="preserve">GstTestClock is an implementation of #GstClock which has different
behaviour compared to #GstSystemClock. Time for #GstSystemClock advances
according to the system time, while time for #GstTestClock changes only
when gst_test_clock_set_time() or gst_test_clock_advance_time() are
called. #GstTestClock provides unit tests with the possibility to
precisely advance the time in a deterministic manner, independent of the
system time or any other external factors.

#GstClock allows for setting up single shot or periodic clock notifications
as well as waiting for these notifications synchronously (using
gst_clock_id_wait()) or asynchronously (using gst_clock_id_wait_async() or
gst_clock_id_wait_async()). This is used by many GStreamer elements,
among them #GstBaseSrc and #GstBaseSink.

#GstTestClock keeps track of these clock notifications. By calling
gst_test_clock_wait_for_next_pending_id() or
gst_test_clock_wait_for_multiple_pending_ids() a unit tests may wait for the
next one or several clock notifications to be requested. Additionally unit
tests may release blocked waits in a controlled fashion by calling
gst_test_clock_process_next_clock_id(). This way a unit test can control the
inaccuracy (jitter) of clock notifications, since the test can decide to
release blocked waits when the clock time has advanced exactly to, or past,
the requested clock notification time.

There are also interfaces for determining if a notification belongs to a
#GstTestClock or not, as well as getting the number of requested clock
notifications so far.

N.B.: When a unit test waits for a certain amount of clock notifications to
be requested in gst_test_clock_wait_for_next_pending_id() or
gst_test_clock_wait_for_multiple_pending_ids() then these functions may block
for a long time. If they block forever then the expected clock notifications
were never requested from #GstTestClock, and so the assumptions in the code
of the unit test are wrong. The unit test case runner in gstcheck is
expected to catch these cases either by the default test case timeout or the
one set for the unit test by calling tcase_set_timeout\(\).

The sample code below assumes that the element under test will delay a
buffer pushed on the source pad by some latency until it arrives on the sink
pad. Moreover it is assumed that the element will at some point call
gst_clock_id_wait() to synchronously wait for a specific time. The first
buffer sent will arrive exactly on time only delayed by the latency. The
second buffer will arrive a little late (7ms) due to simulated jitter in the
clock notification.

Since #GstTestClock is only supposed to be used in unit tests it calls
g_assert(), g_assert_cmpint() or g_assert_cmpuint() to validate all function
arguments. This will highlight any issues with the unit test code itself.</doc>
