Why is ChromeDriver trying to open the site via https?

Question

Google Chrome

I'm running tests in codeception via docker. The application itself starts through the built-in web server in PHP (php -S 0.0.0.0:8080), from containers with selenium/node-chrome and selenium/hub I can pull the link to the site via curl :

selenium/hub

[email protected]:/$ curl -v http://app:8080
* Rebuilt URL to: http://app:8080/
*   Trying 172.23.0.2...
* TCP_NODELAY set
* Connected to app (172.23.0.2) port 8080 (#0)
> GET / HTTP/1.1
> Host: app:8080
> User-Agent: curl/7.58.0
> Accept: */*

Hello World!

But during the tests it can not connect, I get an error

This site can't be reached app unexpectedly closed the connection.

And here is the log in the web server console:

Answer 1

As they wrote in one parable from

Koran

Если гора не идет к Магомету, то Магомет идет к горе

The solution turned out to be easier than I thought. I replaced the standard PHP builtin web server with mpyw/php-hyper-builtin-server

docker-compose.yml

version: "3"

services:
  app:
    image: php:latest
    volumes:
      - ./:/app
    working_dir: /app
    command: vendor/bin/hyper-run -s 0.0.0.0:8080
    depends_on:
      - selenium-hub

  selenium-hub:
    image: selenium/hub:3.141.59-mercury
    depends_on:
      - chrome
    ports:
      - 4444:4444

  chrome:
    image: selenium/node-chrome:3.141.59-mercury
    volumes:
      - /dev/shm:/dev/shm
    environment:
      - HUB_HOST=selenium-hub
      - HUB_PORT=4444
