When using PHPUnit there are different ways to create a code coverage report. By default, XDebug is used. But as mention on different sites, XDebug is very slow and the generation of a code coverage report might take several minutes for big projects.
To speed up things,
phpdbg can be used. This significantly speeds up unit tests and code coverage.
Phpdbg can be used as follows:
phpdbg -qrr ./vendor/bin/phpunit --coverage-text --colors=never
But there are different problems with the code coverage report of phpdbg. For example
phpdbg does not cover a case line of a switch statement:
A better solution to cover this is
pcov, which can be installed using
pecl install pcov
To create a code coverage report, phpunit can be called with:
php -dpcov.enabled=1 -dpcov.directory=. ./vendor/bin/phpunit --coverage-text
To exclude a directory, the following parameter can be used:
php -dpcov.enabled=1 -dpcov.directory=. -dpcov.exclude="~vendor~" ./vendor/bin/phpunit --coverage-text
I don’t know if it’s really a problem with pcov, but: with pcov installed, it is not possible to use phpdbg anymore!
