Mhlongo" Date: Mon, 26 May 2025 18:05:38 +0200 Subject: integration-test: add test for sensors that report non-working buffers Confirm that when a sensor reports support for buffer operation, and the mode can actually be enabled, but no data is returned, iio-sensor-proxy will detect this and switch to polling mode. --- tests/integration-test.py | 36 ++++++++++++++++++++++++++++++++++++ 1 file changed, 36 insertions(+) diff --git a/tests/integration-test.py b/tests/integration-test.py index b596eaa..95b9da3 100755 --- a/tests/integration-test.py +++ b/tests/integration-test.py @@ -630,6 +630,42 @@ class Tests(dbusmock.DBusTestCase): self.stop_daemon() + def test_iio_broken_buffer_accel(self): + '''iio sensor reporting broken buffer support''' + top_srcdir = os.getenv('top_srcdir', '.') + mock_dev_data = self.testbed.get_root_dir() + '/iio-dev-data.bin' + accel = self.testbed.add_device('iio', 'iio-buffer-accel0', None, + ['name', 'IIO Test Accelerometer', + 'buffer/enable', '0', + 'trigger/current_trigger', '', + 'scan_elements/in_accel_x_en', '0', + 'scan_elements/in_accel_x_index', '0', + 'scan_elements/in_accel_x_type', 'le:s16/32>>0', + 'scan_elements/in_accel_y_en', '0', + 'scan_elements/in_accel_y_index', '1', + 'scan_elements/in_accel_y_type', 'le:s16/32>>0', + 'scan_elements/in_accel_z_en', '0', + 'scan_elements/in_accel_z_index', '2', + 'scan_elements/in_accel_z_type', 'le:s16/32>>0', + 'scan_elements/in_timestamp_en', '1', + 'scan_elements/in_timestamp_index', '3', + 'scan_elements/in_timestamp_type', 'le:s64/64>>0'], + ['NAME', '"IIO Accelerometer"', + 'DEVNAME', '/dev/iio-buffer-accel-test', + 'IIO_SENSOR_PROXY_TYPE', 'iio-buffer-accel iio-poll-accel'] + ) + trigger = self.testbed.add_device('iio', 'trigger0', None, + ['name', 'accel_3d-dev0'], + [] + ) + self.start_daemon() + self.assertEqual(self.have_text_in_log('Built channel array'), True) + self.assertEqual(self.have_text_in_log('Disabled sensor'), True) + self.assertEqual(self.have_text_in_log('Found IIO poll accelerometer'), True) + self.assertEqual(self.get_dbus_property('HasAccelerometer'), True) + + self.stop_daemon() + def test_unrequested_readings(self): '''unrequested property updates''' self.testbed.add_device('input', 'fake-light', None,
