Runs tests in parallel by default using 8 threads, significantly speeding up large test suites, as shown by the -j command-line option.

Generates detailed HTML coverage reports with support for Xdebug, PCOV, or PHPDBG, enabled via the --coverage flag for analyzing untested code.

Includes diverse assertions for values, exceptions, errors, and private methods, such as Assert::exception() and Assert::with() for testing private access.

Automatically re-runs tests on code changes with the -w flag, eliminating manual test execution and improving developer workflow.
