Why my tests in parallel don't finish the same way as sequential

[Ana MB]

Hi guys!

I'm running tests from my Jenkins and I've realized that if I run one only test, the result is SUCCESS; but if I run three tests in parallel, that test doesn't finish SUCCESS, it gets timeout.

My docker configuration is:

version: "2"

services:

  selenium:

    networks:

      mynet:

        ipv4_address: 172.25.0.100

    image: bufete/spider-selenium:beta1

    ports:

      - "8080:8080"

  hub:

    networks:

      mynet:

        ipv4_address: 172.25.0.101

    image: selenium/hub

    ports:

      - "5001:4444"

    environment:

      - GRID_BROWSER_TIMEOUT=1400

      - GRID_MAX_SESSION=10

      - GRID_TIMEOUT=120

      - GRID_NEW_SESSION_WAIT_TIMEOUT=-1

#      - GRID_TIMEOUT=900

  chrome:

    image: selenium/node-chrome-debug:3.3.1

    shm_size: 2g

    links:

      - hub

    volumes:

      - /dev/urandom:/dev/random

    depends_on:

      - hub

    environment:

      - HUB_PORT_4444_TCP_ADDR=172.25.0.101

      - HUB_PORT_4444_TCP_PORT=4444

      - NODE_MAX_SESSION=1

      - NODE_MAX_INSTANCES=1

      - SCREEN_WIDTH=1920

      - SCREEN_HEIGHT=1480

      - GRID_TIMEOUT=120

      - no_proxy=""

    networks:

      - mynet

#    ports:

#      - "666:5900"

    volumes:

      - "/dev/shm:/dev/shm"

Do you know how could I get the same result running my tests in parallel???

Thanks so much!!
