When you run tests, they run in series so it can be time consuming. In this example, we are going to run PHPUnit tests in parallel. You can easily change the command to run Behat tests in parallel as well. Just read the documentation.


Installation


Run composer require liuggio/fastest --dev to install Fastest package.


Test

OK (8011 tests, 22023 assertions)

Parallel


By default, 2 parallel processes are run. If you want more speed with 4 parallel processes, you can add -p ${TESTS_PROCESSES:-4} right at the end of the command.


$ vendor/liuggio/fastest/fastest -x "phpunit.xml.dist" "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};" -vv
- 3 shuffled test classes into the queue.

If you want different outputs, you can use one of the commands below.


find tests/ -name "*Test.php" | ./vendor/liuggio/fastest/fastest "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};"

find tests/ -name "*Test.php" | ./vendor/liuggio/fastest/fastest "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};" -v

find tests/ -name "*Test.php" | ./vendor/liuggio/fastest/fastest "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};" -vv

vendor/liuggio/fastest/fastest -x "phpunit.xml.dist" "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};"

vendor/liuggio/fastest/fastest -x "phpunit.xml.dist" "vendor/phpunit/phpunit/phpunit -c phpunit.xml.dist {};" -v
