Downloaded files missing on some parallel containers

Build Environment
1

Hey, i am trying to run protractor tests in parallel.
I’ve modified my circle.yml to this:

test:
pre:
- node ./node_modules/.bin/webdriver-manager update
override:
- node ./node_modules/.bin/protractor:
parallel: true

I am experiencing an inconsistent behavior among containers with this below command, which basically downloads some files:

node ./node_modules/.bin/webdriver-manager update

Updating selenium standalone to version 2.52.0
downloading https://selenium-release.storage.googleapis.com/2.52/selenium-server-standalone-2.52.0.jar…
Updating chromedriver to version 2.21
downloading https://chromedriver.storage.googleapis.com/2.21/chromedriver_linux64.zip…
chromedriver_2.21linux64.zip downloaded to /home/ubuntu/reactMobile/node_modules/protractor/selenium/chromedriver_2.21linux64.zip
selenium-server-standalone-2.52.0.jar downloaded to /home/ubuntu/reactMobile/node_modules/protractor/selenium/selenium-server-standalone-2.52.0.jar

The command is reported green on all containers. However, when i ssh into containers, i find the downloaded files only on the first containers. All the other containers are missing these files. I’ve tested on 2x and 3x parallelism, and tried disabling cache.

Ok, proplem solved. It turns out you are required to add parallel: true to every single line in test section, including test.pre as well:

test:
  pre:
    - node ./node_modules/.bin/webdriver-manager update:
        parallel: true
  override:
    -  node ./node_modules/.bin/protractor:
        parallel: true
