There is no graphical interface.

No. The distributed PHAR bundles all required dependencies of PHPUnit in one file, so there is nothing extra to install by hand.Will it run on my operating system?It is plain PHP, so it runs anywhere PHP does - Linux, macOS and Windows. The README imposes no OS restrictions.

The project is split into a family of small components maintained by its author - php-file-iterator, php-invoker, sebastian/diff, sebastian/exporter, sebastian/type and more - plus third-party packages like nikic/php-parser and theseer/tokenizer.

Code coverage is developed as its own component of the project, php-code-coverage, maintained alongside PHPUnit itself.
Yes. Code coverage is developed as its own component of the project, php-code-coverage, maintained alongside PHPUnit itself.Is it free, and how is development funded?It is free and open source under the BSD-3-Clause license. Sebastian Bergmann's thousands of hours of work are supported through GitHub Sponsors, and companies can back the project to get their logo on the README.
