## Notes

beberlei/assert is a PHP library of assertions and guard methods for checking input. Each assertion, such as `Assertion::integer()` or `Assertion::notEmpty()`, throws an exception when the value does not hold, so the code does not need an if-clause for the same condition. The library validates input and does not filter it. A fluent `Assert::that()` API chains several checks on one value, and lazy assertions collect every failure and throw one combined exception. A project can subclass the assertion class to change the exception it throws and to add its own assertions.
