How to run
The script was tested and ran in
$ php -v
PHP 7.1.8-2+ubuntu16.04.1+deb.sury.org+4 (cli) (built: Aug 4 2017 13:04:12)
But it should also run in Windows and with lower versions of PHP (5.6+). The major concern is the version of PHPUnit to run the tests.
To run, execute
$ $ php balance.php "<string to test>"
For example the following script returns 2
$ php balance.php "{}}"
2
If no string is given to the script, the script displays an error message with instructions.
How to test
The script can be tested using PHPUnit. A PHPUnit phar file is included in the repo for convenience.
To run the tests simply do:
$ ./phpunit.phar tests.php
Should output:
PHPUnit 6.4.3 by Sebastian Bergmann and contributors.
...... 6 / 6 (100%)
Time: 187 ms, Memory: 10.00MB
OK (6 tests, 6 assertions)
