ttn/tea test runner. Execute unit test suite and some other details.
Also used by github for test execution.

Recommended docker version is >=20.10 for xdebug break pointing to work reliably, and
a recent docker-compose (tested >=1.21.2) is needed.

            - composerInstall: "composer update", handy if host has no PHP
            - composerInstallLowest: "composer update", handy if host has no PHP
            - composerInstallHighest: "composer update", handy if host has no PHP
            - coveralls: Execute coveralls to upload coverage to coveralls
            - functional: functional tests
            - lint: PHP linting

            - sqlite: (default) use sqlite
            - mariadb: use mariadb
            - mysql: use mysql
            - postgres: use postgres

    -i <10.2|10.3|10.4|10.5|10.6|10.7>

    -e "<composer, phpunit or codeception options>"
        Only with -s functional|unit|composer
        Additional options to send to phpunit (unit & functional tests) or codeception (acceptance
        tests). For phpunit, options starting with "--" must be added after options starting with "-".
        Example -e "-v --filter canRetrieveValueWithGP" to enable verbose output AND filter tests
        named "canRetrieveValueWithGP"

    -x
        Only with -s functional|unit
        Send information to host instance for test or system under test break points. This is especially
        useful if a local PhpStorm instance is listening on default xdebug port 9003. A different port
        can be selected with -y

    -y <port>
        Send xdebug information to a different port than default 9003 if an IDE like PhpStorm
        is not listening on default port.

    -z <xdebug modes>
        Only with -x and -s functional|unit|acceptance
        This sets the used xdebug modes. Defaults to 'debug,develop'

    -n
        Only with -s cgl
        Activate dry-run in CGL check that does not actively change files and only prints broken ones.

    -u
        Update existing typo3/core-testing-*:latest docker images. Maintenance call to docker pull latest
        versions of the main php images. The images are updated once in a while and only the youngest
        ones are supported by core testing. Use this if weird test errors occur. Also removes obsolete
        image versions of typo3/core-testing-*.

    -v
        Enable verbose script output. Shows variables and docker commands.

    -h
        Show this help.

Examples:
    # Run unit tests using PHP 7.4
    ./Build/Scripts/runTests.sh -s unit
EOF
