GstCheck

These macros and functions are for internal use of the unit tests found inside the 'check' directories of various GStreamer packages.

One notable feature is that one can use the environment variables GST_CHECKS and GST_CHECKS_IGNORE to select which tests to run or skip. Both variables can contain a comma separated list of test name globs (e.g. test_*).

                                 const gchar * name)

Creates a new src pad (based on the given tmpl) and links it to the given element sink pad (the pad that matches the given name). Before using the src pad to push data on element you need to call gst_check_setup_events on the created src pad.

Example of how to push a buffer on element:

 static GstStaticPadTemplate sinktemplate = GST_STATIC_PAD_TEMPLATE ("sink",
 GST_PAD_SINK,
 GST_PAD_ALWAYS,
 GST_STATIC_CAPS (YOUR_CAPS_TEMPLATE_STRING)
 );
 static GstStaticPadTemplate srctemplate = GST_STATIC_PAD_TEMPLATE ("src",
 GST_PAD_SRC,
 GST_PAD_ALWAYS,
 GST_STATIC_CAPS (YOUR_CAPS_TEMPLATE_STRING)
 );

 GstElement * element = gst_check_setup_element ("element");
 GstPad * mysrcpad = gst_check_setup_src_pad (element, &srctemplate);
 GstPad * mysinkpad = gst_check_setup_sink_pad (element, &sinktemplate);

 gst_pad_set_active (mysrcpad, TRUE);
 gst_pad_set_active (mysinkpad, TRUE);
 fail_unless (gst_element_set_state (element, GST_STATE_PLAYING) == GST_STATE_CHANGE_SUCCESS, "could not set to playing");

 GstCaps * caps = gst_caps_from_string (YOUR_DESIRED_SINK_CAPS);
 gst_check_setup_events (mysrcpad, element, caps, GST_FORMAT_TIME);
 gst_caps_unref (caps);

 fail_unless (gst_pad_push (mysrcpad, gst_buffer_new_and_alloc(2)) == GST_FLOW_OK);

#define fail_unless_equals_uint64_hex(a, b)                             \
G_STMT_START {								\
  guint64 first = a;							\
  guint64 second = b;							\
  fail_unless(first == second,						\
    "'" #a "' (0x%016x) is not equal to '" #b"' (0x%016x)", first, second);\
} G_STMT_END;

This macro checks that a and b are equal and aborts if this is not the case, printing both expressions and the values they evaluated to in hexadecimal format. This macro is for use in unit tests.

Parameters:

a –

a gint64 value or expression

b –

a gint64 value or expression

This macro checks that a matches the regular expression in b aborts if this is not the case, printing both expressions and the values they evaluated to. This macro is for use in unit tests.

Parameters:

a –

a string literal or expression

b –

a regular expression pattern string literal or expression
