Since I don't know why gr_modtool doesn't work for me, I took the older
working version and made very simple hier block in order to understand
messages flow in gnuradio.
The block code is following:
from gnuradio import gr
class msg_proba(gr.hier_block2):
def __init__(self, ):
gr.hier_block2.__init__(self, "msg_proba",
gr.io_signature(1, 1, gr.sizeof_char), # Input signature
gr.io_signature(1, 1, gr.sizeof_char)) # Output signature
gr_message_sink_0_msgq_out = gr_message_source_0_msgq_in =
gr.msg_queue(4)
self.gr_message_source_0 = gr.message_source(gr.sizeof_char*1,
gr_message_source_0_msgq_in)
self.gr_message_sink_0 = gr.message_sink(gr.sizeof_char*1,
gr_message_sink_0_msgq_out, False)
self.connect(self, self.gr_message_sink_0)
self.connect(self.gr_message_source_0, self)
and the test code is following:
from gnuradio import gr, gr_unittest
import test
import msg_proba
class qa_msg_proba (gr_unittest.TestCase):
def setUp (self):
self.tb = gr.top_block ()
def tearDown (self):
self.tb = None
def test_001_msg_proba (self):
self.src_data = ()
self.expected_result = ()
for i in range(51):
self.src_data = self.src_data + (1,)
self.expected_result = self.expected_result+(1,)
self.src = gr.vector_source_b(self.src_data, False, 1)
self.dst = gr.vector_sink_b ()
self.msg_pr = msg_proba.msg_proba()
self.tb.connect(self.src, self.msg_pr, self.dst)
self.tb.run ()
# check data
result_data = dst.data ()
self.assertEqual (expected_result, result_data)
if __name__ == '__main__':
gr_unittest.main ()
When I run test, it doesn't finish. No errors, just stays active without
giving any results.
Can somebody provide some explanation?
