How to initiate chromedriver, when running Flutter Integration Tests on Gitlab Pipeline

Question

I currently have a project, where Flutter Integration Tests are required to be run on a GitLab pipeline. I initiate the download/install of Chrome and ChromeDriver via .gitlab-ci.yml file, which appears to work successfully. I then try and start ChromeDriver with chromedriver --port=4444 before running my first test. The error received is:

> $ chromedriver --port=4444 /bin/bash: line 266: chromedriver: command
> not found

How do I initiate ChromeDriver in this scenario?

# Code to start chromedriver
.webapp:test: &webapp_test
  image: $CI_REGISTRY_IMAGE/flutter:latest
  script:
    - apt-get update && apt-get install -y jq
    - cd $APP_DIR
    - cd /chromedriver/
    - chromedriver --port=4444

FYI, code to install Chrome and ChromeDriver:

webapp:test:
  extends: .webapp:test
  stage: test
  allow_failure: true
  before_script:
    # Chrome and ChromeDriver dependencies
    - cd $APP_DIR
    - apt-get install -y wget unzip
    - wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
    - echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list
    # Update the package list
    - apt-get update -y
    # Download and Install chrome
    - wget --no-verbose -O /tmp/chrome.deb https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb && apt install -y /tmp/chrome.deb && rm /tmp/chrome.deb
    # Download and install Chromedriver
    - mkdir /chromedriver
    - wget -q --continue -P /chromedriver "https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/120.0.6099.109/linux64/chromedriver-linux64.zip"
    - unzip /chromedriver/chromedriver* -d chromedriver

Thanks, I am new to this as you can probably tell

Answer 1

Suppose that you want to run the following script:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()

options.add_argument("--no-sandbox")
options.add_argument("--headless")
options.add_argument("--window-size=1920,1080")

driver = webdriver.Chrome(options=options)
driver.get('http://www.example.com')

print(driver.page_source)

The GitLab CI setup could be something like this:

chrome:
  image: python:3.11.4
  stage: test
  before_script:
    - apt-get update && apt-get install -y wget unzip
    # Chrome
    - wget -q https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
    - apt install -y ./google-chrome-stable_current_amd64.deb
    - rm google-chrome-stable_current_amd64.deb
    - ln -s /opt/google/chrome/chrome /usr/local/bin/
    # Chromedriver
    - wget -q https://edgedl.me.gvt1.com/edgedl/chrome/chrome-for-testing/120.0.6099.109/linux64/chromedriver-linux64.zip
    - unzip -j chromedriver-linux64.zip chromedriver-linux64/chromedriver
    - rm chromedriver-linux64.zip
    - mv chromedriver /usr/local/bin/
    - chrome --version
    - chromedriver --version
    - pip3 install selenium
  script:
    - python3 run.py

Script runs and dumps contents of http://www.example.com.
