Currently, we want to implement parallel processes in our automation testing because it took long time about 1 hour 35 minutes in single process.
So we have 1 selenium hub container, 4 proxy containers and 4 chrome-debug containers which every proxy container connected to chrome-debug container each other.
Here is the result of athena info command :

 [INFO] Running containers [image|container|status]:

Here is the result of docker ps :

Then we do athena php bdd . athena.bdd.m.json --browser=chrome --config=behat-mobile.yml --parallel-process=4, here the result:

Hello @fergadipaolx

After doing a few tests on our own, we've reached a few conclusions:

  • We can have a single proxy container which will be shared across all nodes and the container where the tests run in. This means it's possible to run parallel tests with a single proxy container but not with multiple.
  • The current version of the BrowserMob Proxy is actually throwing random null pointer exceptions when we run multiple tests at the same time

We've create a list of steps you can follow to have parallel tests running with a single proxy container:

  • echo 'PROXY_VERSION=2.1.4' > /tmp/proxy.env – use the latest version of BrowserMob proxy since it's one we managed to have parallel tests running in
  • athena proxy start --athena-env=/tmp/proxy.env – start the single proxy container
  • athena selenium start hub latest
  • athena selenium start firefox latest --instances=2 – this will start 2 firefox containers and link them automatically to the hub and proxy
  • Clone athena-oss/plugin-php repository
  • Go inside the directory where the repository is and do cd ./example-tests

Replace the contents of./Bdd/Features/AnonymousUserSearch.feature with the text below:
(continues below..)

Feature: Anonymous User performs a search

  As a Anonymous User
  I want to perform a search for a string
  So that I can get a list of results related with my search

  @parallel-scenario
  Scenario: Searched string returns results
    Given the current location is the home page
    When the Anonymous User writes "athena" in the search box
    And the Anonymous User performs a click in the search button
    Then the current location should be results page

  @parallel-scenario
  Scenario: Searched string returns results
    Given the current location is the home page
    When the Anonymous User writes "athena" in the search box
    And the Anonymous User performs a click in the search button
    Then the current location should be results page

  @parallel-scenario
  Scenario: Searched string returns results
    Given the current location is the home page
    When the Anonymous User writes "athena" in the search box
    And the Anonymous User performs a click in the search button
    Then the current location should be results page
  • athena php bdd . athena.json --parallel-process=2 --browser=firefox – this will start two scenarios in parallel and use the firefox browsers we started in the beginning

Let me know if this works.
