      If using TEST_EXTERNAL_FILES_HTTP_URL, ensure they aren't server from 127.0.0.1 / localhost, but local IP instead, that way the proxy configured in the test is used and the expectations are correct.

      Preparations

      1. Open a terminal
      2. Start the exttests docker image: 

        docker run -p 2080:80 moodlehq/moodle-exttests

      3. In config.php setup this: 

        define('TEST_EXTERNAL_FILES_HTTP_URL', 'http://localhost:2080');

      4. Go to the browser open http://localhost:2080/test.jpg
      5. Verify that you see a snowman picture (that means that "exttests" are being server correctly).
      6. Init phpunit 

        php admin/tool/phpunit/cli/init.php

      7. Run "core_rsslib_testcase". 

        vendor/bin/phpunit -v "core_rsslib_testcase" lib/tests/rsslib_test.php

      8. Verify that the test ends without errors (4 tests OK).

      Recently I started getting this failure in all my local phpunit tests:

      $ vendor/bin/phpunit -v "core_rsslib_testcase" lib/tests/rsslib_test.php

      FAILURES!
      		 
      Tests: 4, Assertions: 26, Failures: 1.

      Any database, any php version, all moodle branches... and 100% consistently.

      After looking a lot and confirming that there wasn't any change... I realised that, recently, I installed the exttests locally and I've them available under http://localhost... url.

      Problem is that such url matches the default CFG->proxybypass values, hence CURL operations don't use the proxy configuration when accessing to them.

      And the failing test is EXACTLY about to to use a wrong proxy configuration and detect that an error is returned. But that wrong proxy configuration isn't used (because of the reason explained above) and the rss feed is fetched without problem. Hence, the test fails.

      So this issue is about to ensure, in that exact test only, that the wrong proxy is used and not excluded because of CFG->proxybypass.
