@Art4 Do you think something like this is reasonable?

I tried finding a library for the PHP server but after reviewing the following, I gave up and wrote my own helper class:

• https://packagist.org/packages/internations/http-mock
  • no PHP 8 support
  • incompatible dependencies
  • no open port selection
  • unmaintained
• https://packagist.org/packages/pagely/http-mock
  • fork of the above
  • no open port selection
  • still incompatible dependencies
  • unmaintained
• https://packagist.org/packages/elnoro/php-http-mock
  • 👍 minimal codebase
  • requires PHP 8
  • no open port selection
  • no released versions
• https://github.com/LibreSign/behat-builtin-extension
  • 👍 minimal codebase
  • 👍 open port selection
  • undeclared behat dependency
  • AGPL licensed
• https://packagist.org/packages/mcustiel/phiremock-server
  • complex configuration
• https://packagist.org/packages/ciareis/bypass
  • old version still supports PHP 7.2
    • but port autodetection only works on PHP 8 (using php -S localhost: flag)

I would have said that it is not worth the effort to create such a test because the File class will be deprecated. But since you've already done the work, we can keep the test. Requiring a separate library for it would definitely be too much.

I've found this library for mocking a webserver: https://packagist.org/packages/donatj/mock-webserver

• 👍 still supports PHP 7.1 up to PHP 8.4
• 👍 open for port and host selection
• 👍 maintained
• all (only 1) dependencies are compatible
• MIT licence

I've looked into the code and it looks very good and straight forward. I've added it in #909.

This was superseded by #909.

The test cases are ported to the new infrastructure in #918.
