1. run phpunit test class
phpunit —bootstrap src/Email.php tests/EmailTest

• phpunit - invokes the PHPUnit command-line test runner. We assume that you have downloaded phpunit.phar (see above) and put it into your $PATH as phpunit.
• —bootstrap src/Email.php - instructs the PHPUnit command-line test runner to include src/Email.php before the test execution.
• Usually, though, you use —bootstrap to instruct the PHPUnit command-line test runner to include bootstrap script that sets up autoloading for the classes that are to be tested. Such a script is commonly generated using tools such as Composer or phpab.
• tests/EmailTest - instructs the PHPUnit command-line test runner to execute the tests of the EmailTest class that is declared in tests/EmailTest.php.
• Using tests instead of tests/EmailTest would instruct the PHPUnit command-line test runner to execute all tests found declared in *Test.php source code files in the tests directory.

2. for alternative output
phpunit —bootstrap src/Email.php —testdox tests
