BlazeMeter/JMeter Issue: JUnit Sampler ClassNotFoundException - performance

I'm new to BlazeMeter and JMeter.
I created a simple Selenium JUnit Script, it can run in IDE.
I then loaded the script into JMeter using JUnitSampler. I run the test in JMeter on my local and it was able to run. Then I uploaded the .jmx file to BlazeMeter and when I try to run it, it would fail.
If I look into the Logs page on BlazeMeter, it complains ClassNotFoundException. Can anybody tell me what's wrong?
2017-11-23 20:16:47,497 WARN o.a.j.p.j.s.JUnitSampler: ClassNotFoundException:: xxxxxx.SampleLoadTest2
And on BlazeMeter Failed Report Summary page, it shows
Error Running Test
The test encountered the following fatal error, and could not complete successfully:
Error: r-v3-5a172c6260523 - Session ended without load report data

you most probably didn’t add the required libraries on Blazemeter (selenium jars...)
So ensure you add them and it should work

Jmeter test status on non-gui mode

How can i get jmeter test status in non-gui mode.
Jenkins install jmeter helm chart on kuberntes and start the test as part of the installation, meaning that after the chart installed a script entry point will run automatically inside the container, jenkins is only trigger the chart. i want to know when the test is finished and get back the status to jenkins from the pod to publish the report test result on jenkins.
When JMeter's non-gui test execution is finished it returns a normal exit code which can be obtained:
%errorlevel% environment variable in Windows
$? environment variable in Unix and derivatives
Not knowing the details of how you launch JMeter it is quite hard to come up with exact Jenkins configuration but I'm pretty much sure that you can utilize the aforementioned variables to get the JMeter execution status
if you are triggering jmeter scripts via jenkins , you can have a post build operation after script execution using jenkins.
I am using powershell in jenkins to run jmeter in non gui mode, once test is done doing other post build operations.

Not able to run jmeter script in non gui mode. It is recorded using blazemeter and running on jmeter 5 version

When Running the JMX script from terminal on MAC IN NON-GUI Mode, it returns an error saying "Could not open"
Below are the things i have tried :
1) jmeter -n -t "ABSOLUTE PATH.jmx" -l ABSOLUTE-PATH for results.jtl
2) Set the jmeter path and tried again.
I get the same error every time.
I don't think you can run the recording using JMeter as BlazeMeter Chrome Extension exports recorded scripts in YAML format suitable for Taurus tool
So you can run it using Taurus tool as
bzt test-Combined-JMeter-and-Selenium.yaml
If you want to convert it to "vanilla" JMeter - execute the following command:
bzt test-Combined-JMeter-and-Selenium.yaml -gui
JMeter GUI will open where you will be able to modify and save generated JMeter script as .jmx file which can be executed using JMeter.

I am getting Assertion Failed error while running jmeter script But I have not used assertions in my script

I am getting Assertion Failed error while running jmeter script But I have not used assertions in my script.
I was doing Load testing with 500 users and getting Assertion Failure errors
Most probably your script fails to download at least one so called "embedded resources" - image, script, style, font, etc. If you are not interested in the problems with the embedded resources - you can turn JMeter automatic check for HTTP Status code < 400 by adding the next line to user.properties file:
httpsampler.ignore_failed_embedded_resources=true
JMeter restart will be required to pick the property up.
If you don't want the change to be permanent you can pass it on ad-hoc basis using -J command-line argument like:
jmeter -Jhttpsampler.ignore_failed_embedded_resources=true -n -t test.jmx -l result.jtl

Sending data failed. Please try again error when exporting from blazemeter

I have recorded the the scenario with blazemeter plugin and then trying to export it into .jmx file, but its giving me error as "Sending data failed. Please try again." Please suggest me how can I export the file into .jmx, and why the error is occurring
First, download the file in json format and then go to http://converter.blazemeter.com/, upload your json file and download it in .jmx format.
P.S.: -it is possible Jmeter throw you an error when you will open the file (so, for this you will need to download a - plugin.manager.jar and from Jmeter -> Options / Plugins Manager install "Throughput Shaping Timer")

How to Run Selenium code in webtest?

I am new to webtest and I read that it is possible to record script in selenium and then run it via webtest/fitnesse. I have got webtest and selenium installed and configured. Is there specific format of code that suites webtest? Any help regarding this will be appreciated
The doc is now more complete: http://webtest.pythonpaste.org/en/latest/modules/sel.html
You need to run java -jar selenium-server.jar
Then write your test like with the TestApp but using SeleniumApp
