Experience using Taurus to run a WebSocket Jmeter Test

[jeffl...@gmail.com]

I am having a bit of trouble trying to use Taurus to run my Websocket JMeter test. The test runs fine when I run from JMeter itself, but blows up if I try to run it via Taurus. I know it is the websocket plugin (when test is invoked by Taurus) that causes it. I had another test which runs fine using Taurus, and dropping in a WebSocket sampler, causes the same issue.  Any ideas as to what to do? I am using the latest Taurus (Taurus CLI Tool v1.6.5) and JMeter (3.0 r1743807)

Here is the pertinent log entry from JMeter.log:

Hi,

Probably Taurus inserted something malformed into JMX when applying load profile. Do you mind sending us your 'modified_e2eWebsocket.jmx' file so we can take a look?

Nonono. This kind of message is typical when JMeter JMX file uses plugin that is not installed into particular JMeter folders.
