If I have multiple thread group inside a single JMX file, is it possible to trigger any specific thread group of that JMX from the yml. If so, could you please provide a sample yml

Regards

Hi,

Yes, it is achievable. To use it, you should rely on thread group naming in JMX + modification feature in Taurus.

Let's assume you have 3 thread groups inside your existing.jmx file, named "Thread Group 1", "Thread Group 2", "Thread Group 3". If you want to have only Thread Group 2 running, your config would be:

---
scenarios:
my-jmx:
    script: existing.jmx
    modifications:
      disable:
         - "Thread Group *"
      enable:
         - "Thread Group 2"

execution:
- scenario: my-jmx
    concurrency: 10
    hold-for: 5

To make sure you have it working properly, try running it with "bzt modif.yml -gui", it will open JMeter GUI to see resulting test plan.

By using "modifications" feature you first say to disable all components which start with "Thread Group ", then enable thread group named "Thread Group 2". These modifications apply to all elements of JMX, you can disable samplers, controllers, configs, anything.

Hi Andrey,

Thanks for the solution. But when I upgraded my Yaml file to include the suggested changes, the tests is not getting executed. I am attaching both the yaml files for your reference.

Before updating:

---

execution:

concurrency: 10

ramp-up: 1m

steps: 5

hold-for: 2m30s

scenario:

script: test.jmx

variables:

smphost: xxxxxxxxxx

smpport: 8080

After Updating:

---

scenarios:

my-jmx:

script: test.jmx

modifications:

disable:

- "Test*"

enable:

- "Test2"

execution:

- scenario: my-jmx

concurrency: 10

ramp-up: 1m

hold-for: 5

variables:

smphost: xxxxx

smpport: 8080

While I am running i am getting the below error:

Can you run it with -gui option to see what components do you have disabled/enabled and make sure it matches your expectation?

Hi Andrey,

I tried that and it correctly disables the threadgroup which i have specified in the yml. It encounters the error once i start executing the test.

Do you have any errors in your jmeter.log file?

Can't it be that you have disabled all the items?

I guess you don't notice that your whole Test Plan is called starting with "Test" and was also disabled. Try renaming it. Or change naming for thread groups.

Hi Andrey,

I get some errors in the Jmeter. But this error comes only if i run the yml with the modification option enabled. If i run the yml without the modifications it runs absolutely fine.
