Summary

the --no-extensions cli option does not apply to the element configured in the config file

Current behavior

while passing the --no-extensions cli option, extensions configured in the extension element of phpunit.xml are loaded when running phpunit.

How to reproduce

Add any extensions to the configuration. Run tests with --no-extensions.
Extensions are loaded.

Expected behavior.

The extensions configured in the extension element are not loaded

A potential issue

phpunit/src/TextUI/TestRunner.php

Line 1009 in 7e7adbd

if (!isset($this->arguments['noExtensions'])) {

The $this->arguments variable used isn't defined. There is no $this->arguments variable, only $arguments.

Solution proposal

Replace $this->arguments with $arguments
