Hi Mike,
I have used a proxy to sit between the client and the server in the
past to simulate network outages. There is one in the test material
which I plan to use -
https://git.eclipse.org/c/paho/org.eclipse.paho.mqtt.testing.git/tree/interoperability/mqtt/proxy/mqttsas.py
This particular version breaks the connection when a particular
combination of topic and payload is published through it
(packet.topicName == "MQTTSAS topic" and \ packet.data ==
"TERMINATE")
I've used different trigger events in the past too.

Hi Ian,
I fixed maven build file to run
existing
jasmine _javascript_ tests awhile back,. Currently, I run "mvn
test" manually and the existing tests pass. I am writing
jasmine
tests for the functionality that I just added. The challenge is
to
simulate network outage to test automatic reconnect and offline
buffering.
If anyone knows how to do this within a test framework, please
let me know.
I just looked at Travis-CI.
Travis-CI
supports _javascript_ with node.js https://docs.travis-ci.com/user/languages/_javascript_-with-nodejs. I am not sure if we can use it for
our _javascript_ client.

_javascript_ Client

Hi Mike,
that's great, thanks! James and I will be taking a look at it
soon.
Is there any progress on automated build and testing? We're
just
starting to use Travis-CI for the Java and C clients.

Hi all,
I have completed the development and
manual
testing of automatic reconnect and offline buffering for
_javascript_ client.
You can see the summary of changes on github under this pull
request
https://github.com/eclipse/paho.mqtt._javascript_/pull/72
The code is available here: https://github.com/miketran78727/paho.mqtt._javascript_
(src/mqttws31.js)
To enable offline buffering, set
disconnectedPublishing
= true. Default offline buffer size is 5000, it can be set via
disconnectedBufferSize
property. Here is an example:
var client
= new Paho.MQTT.Client(server, port, clientId);
client._onConnected_ = onConnected;
client._onConnectionLost_ = onConnectionLost;
client._onMessageArrived_ = onMessageArrived;
client._onMessageDelivered_ = onMessageDelivered;
client.disconnectedPublishing = true;
client.disconnectedBufferSize = 100;
To enable automatic reconnect, set
reconnect
option to true, e.g.:
client.connect(
{cleanSession
: false,
onSuccess : onConnectSuccess,
onFailure : onFailedConnect,
keepAliveInterval : 10,
reconnect : true});
I have manually tested the code and I
have
not found any regression. I would appreciate additional testing
and feedback.
