Member Function Documentation

_assert_bag_valid()

def test_snapshot.TestRosbagSnapshot._assert_bag_valid (   self,   filename,   topics = None,   start_time = None,   stop_time = None  )

private

Open the bagfile at the specified filename and read it to ensure topic limits were
enforced and the optional topic list and start/stop times are also enforced.

Definition at line 172 of file test_snapshot.py.

_assert_limits_enforced()

def test_snapshot.TestRosbagSnapshot._assert_limits_enforced (   self,   test_topic,   duration,   memory,   count  )

private

Asserts that the measured duration and memory for a topic comply with the launch parameters
@param topic: string
@param duration: rospy.Duration, age of buffer
@param memory: integer, bytes of memory used
@param count: integer, number of messages stored

Definition at line 137 of file test_snapshot.py.

_assert_no_data()

def test_snapshot.TestRosbagSnapshot._assert_no_data (   self,   topics = []  )

private

Asserts that calling TriggerWrite service with
specifed parameters responds non-success and did not create
a bag file.

Definition at line 88 of file test_snapshot.py.

_assert_record_success()

def test_snapshot.TestRosbagSnapshot._assert_record_success (   self,   data  )

private

Assert that the recording SetBool service responds with success

Definition at line 100 of file test_snapshot.py.

_assert_status_valid()

def test_snapshot.TestRosbagSnapshot._assert_status_valid (   self )

private

Check that a status message contains info on all subscribed topics
and reports that their buffer complies with the configured limits.

Definition at line 155 of file test_snapshot.py.

_assert_write_success()

def test_snapshot.TestRosbagSnapshot._assert_write_success (   self,   topics = [],   prefix_mode = False,   kwargs  )

private

Asserts that the TriggerWrite services succeeds for the specified request arguments
and that the specified bag file is actually created
@param prefix_mode: If True, don't put .bag at the end of reqest to check prefix filename mode

Definition at line 114 of file test_snapshot.py.

_parse_params()

def test_snapshot.TestRosbagSnapshot._parse_params (   self,   params  )

private

Parse launch parameters of snapshot to cache the topic limits in a map
so it is easier to check compliance in later tests.

Definition at line 60 of file test_snapshot.py.

_pause()

def test_snapshot.TestRosbagSnapshot._pause (   self )

private

Definition at line 108 of file test_snapshot.py.

_resume()

def test_snapshot.TestRosbagSnapshot._resume (   self )

private

Definition at line 111 of file test_snapshot.py.

_status_cb()

def test_snapshot.TestRosbagSnapshot._status_cb (   self,   msg  )

private

Definition at line 85 of file test_snapshot.py.

test_1_service_connects()

def test_snapshot.TestRosbagSnapshot.test_1_service_connects

(

self

)

Check that both services provided by snapshot exist.

Definition at line 199 of file test_snapshot.py.

test_invalid_topics()

def test_snapshot.TestRosbagSnapshot.test_invalid_topics

(

self

)

Test that an invalid topic or one not subscribed to fails

Definition at line 247 of file test_snapshot.py.

test_write_advanced()

def test_snapshot.TestRosbagSnapshot.test_write_advanced

(

self

)

Test the more advanced features: pausing and resuming, specific write times, and specific topic list.

Definition at line 215 of file test_snapshot.py.

test_write_all()

def test_snapshot.TestRosbagSnapshot.test_write_all

(

self

)

Wait long enough for memory & duration limits to need to be used
