Mock data update while running the config.yml file

[PoojaArora29]

Hi all,

i am using artillery for a miniapp which has graphql queries. So far it works fine when i have loaded the mocks when i do yarn start but i have couple of scenario for which i want to use different mocks that changes the response of the scenario.
Currently i have .js file to overwrite the mock file which worked fine in local but it does not work when using docker images.

Version info:
Artillery : 2.0.0-35
Node.js : v16.18.1

Running this command:
Local : yarn performance-test-bff
Jenkins/docker : ./batect performance-test-bff

I expected to see this happen:

Local: overwrite files to use new mock (cannot think any simpler way than this otherwise yarn start is required to take mock effect)

Instead, this happened:

Works fine in local need it the same solution for docker.

Files being used:

Commands in sequence from batect to app/server/package.json

Batect.yml

performance-test-bff:
  description: Run bff performance tests
  run:
      container: build-env
      command: yarn performance-test-bff
      environment:
          ARTILLERY_ENVIRONMENT: dev
          ARTILLERY_ARRIVAL_RATE: 1
          ARTILLERY_DURATION: 60
          HTTP_PROXY: ''
  dependencies:
      - express
      - mocks
 

Root/package.json

“ performance-test-bff": "yarn workspace server performance-test"

App/server/package.json

“ performance-report": "artillery report --output ./performance/results/bff-performance-test-report.html performance/results/bff-performance-test-report.json",
"performance-run": "arrivalRate=$ARTILLERY_ARRIVAL_RATE duration=$ARTILLERY_DURATION artillery run -e $ARTILLERY_ENVIRONMENT --output ./performance/results/bff-performance-test-report.json ./performance/config.yml",
"performance-test": "yarn preperformance-test && yarn performance-run && yarn performance-report",
"preperformance-test": "rimraf ./performance/results && mkdirp ./performance/results "

i have added one scenario here but actually there are multiple flows in my actual project. I am using same scenario in the same file and using helper.json to update mocks while running perf. This approach works in local but when i run it in jenkins it used docker.

please ignore indentation and spellings . It is just copy pasted and manually entered from mobile 😭😭

Thanks a lot for your help
