Hi
Can we do trace testing using signoz as backend ? or is there any other way to do trace testing after setting up signoz with otel ?
I deployed signoz using helm chart on my kubernetes cluster and I can able to see the traces.

What kind of testing do you want to enable using traces? Can you please give me some examples?

Okay

Below screenshot I am getting users from my microservice

My tracetest definition file is

type: Test
spec:
  name: Go Get users
  description: "Get users"
  trigger:
    type: http
    httpRequest:
      url: 
      method: GET
      headers:
      - key: Content-Type
        value: application/json
  specs:
    - selector: span[name = "GET /users"]
      assertions:
        - attr:tracetest.span.duration <= 500ms
        - attr:http.status_code = 200
  outputs:
    - name: USER_ID
      selector: span[name = "GET /users"]
      value: attr:http.response.body | json_path '.id'
