Я через composer ставлю phpunit/dbunit. При запуске CI тестов phpunit на codeship сразу же получаю ошибку:

PHP Fatal error:  Class 'PHPUnit_Extensions_Database_TestCase' not found in home/rof/src/bitbucket.org/user/project/tests/DatabaseTestCase.php on line 4

Содержимое composer.json:

{
	"require": {
		"php": ">=5.6.0",
		"videlalvaro/php-amqplib": "2.5.*",
		"composer/installers": "~1.0"
	},
	"require-dev": {
		"phpunit/phpunit": "5.1.*",
		"phpunit/dbunit": ">=1.2"
	}
}

Setup Commands:

# Set php version through phpenv. 5.3, 5.4, 5.5 & 5.6 available
phpenv local 5.6
# Install extensions through Pecl
yes yes | pecl install memcache
# Install dependencies through Composer
composer install --prefer-source --no-interaction
./bin/provision/db

Configure Test Pipelines:

phpunit --bootstrap=./tests/bootstrap.php tests/

При этом на виртуальной машине при поставленном через pecl dbunit/phpunit всё ок.
