Assert

This is a simple library that contains a function to asset conditions.

Installation

composer require tebru/assert:~0.2

Usage

Using the generic assert functions, you must pass a condition as the first argument.

Simple

The easiest and most generic way to use this library is through assertThat(). This will throw a LogicException with a default message that is easily customized.

Tebru\assertThat(false);
Tebru\assertThat(1 === 2);
Tebru\assertThat(false, 'My %s %s', 'test', 'message');

Changing exceptions

If you need to throw specific exceptions, that can be done through assert(). The method defaults to throwing a LogicException.

Tebru\assert(false);
Tebru\assert(1 === 2);
Tebru\assert(false, new \InvalidArgumentException('My custom error message'));

Additional Functions

There are a number of additional functions that assert specific conditions. Each one accepts a message and a variable number of arguments to be used with an sprintf function as the final arguments. A list is provided below with the method definition:

• assertEqual($expected, $actual, $message = null, $_ = null)
• assertNotEqual($expected, $actual, $message = null, $_ = null)
• assertSame($expected, $actual, $message = null, $_ = null)
• assertNotSame($expected, $actual, $message = null, $_ = null)
• assertTrue($value, $message = null, $_ = null)
• assertFalse($value, $message = null, $_ = null)
• assertNull($value, $message = null, $_ = null)
• assertNotNull($value, $message = null, $_ = null)
• assertArrayKeyExists($key, array $search, $message = null, $_ = null)
• assertArrayKeyNotExists($key, array $search, $message = null, $_ = null)
• assertCount($expected, $countable, $message = null, $_ = null)

Advanced Usage

Starting with php 5.6, you can import functions

<?php

namespace Foo;

use function Tebru\assert;

assert(false);
