  GStreamer | gstreamer (core) | Ver: HEAD CVS
           Summary: [unit testing] add a function that automatic push
                    buffers and check the result
           Product: GStreamer
           Version: HEAD CVS
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gstreamer (core)

     GNOME version: Unspecified
   GNOME milestone: Unspecified


I think we can use some more functions that automate the testing process.
Proposed is a patch that adds two functions:

* gst_check_element_push_buffer_list (const gchar *element_name, GList
*buffer_in, GList *buffer_out, GstFlowReturn last_flow_return)

this function creates the element with the element_name and pushes all buffers
in buffer_in to the element and checks if the output of this element is the
same as the buffers in buffer_out. last_flow_return is a bonus to check what
the push of the last packet need to be.

*gst_check_element_push_buffer (const gchar *element_name, GstBuffer
*buffer_in, GstBuffer *buffer_out)
a small wrapper that takes 1 buffer in and out and expect GST_FLOW_OK

This can remove a lot of redundant code out of the unit test's to keep an
overview.
