BDD Assertions for [PHPUnit][1] and [Codeception][2]

This is very tiny wrapper for PHPUnit assertions, that are aimed to make tests a bit more readable.
With [BDD][3] assertions influenced by [Chai][4], [Jasmine][5], and [RSpec][6] your assertions would be a bit closer to natural language.

[![Build Status](https://travis-ci.org/Codeception/Verify.png?branch=master)](https://travis-ci.org/Codeception/Verify) [![Latest Stable Version](https://poser.pugx.org/codeception/verify/v/stable.png)](https://packagist.org/packages/codeception/verify)

```php
$user = User::find(1);

// equal
verify($user->getName())->equals('davert');
verify("user have 5 posts", $user->getNumPosts())->equals(5);
verify($user->getNumPosts())->notEquals(3);

// contains
verify('first user is admin', $user->getRoles())->contains('admin');
verify("first user is not banned", $user->getRoles())->notContains('banned');

// greater / less
$rate = $user->getRate();
verify('first user rate is 7', $rate)->equals(7);

verify($rate)->greaterThan(5);
verify($rate)->lessThan(10);
verify($rate)->lessOrEquals(7);
verify($rate)->lessOrEquals(8);
verify($rate)->greaterOrEquals(7);
verify($rate)->greaterOrEquals(5);

// true / false / null
verify($user->isAdmin())->true();
verify($user->isBanned())->false();
verify($user->invitedBy)->null();
verify($user->getPosts())->notNull();

// empty
verify($user->getComments())->isEmpty();
verify($user->getRoles())->notEmpty();
```

Shorthands for testing truth/fallacy:

```php
verify_that($user->isActivated());
verify_not($user->isBanned());
```

These two functions don't check for strict true/false matching, rather `empty` function is used.
`verify_that` checks that result is not empty value, `verify_not` does the opposite.

## Alternative Syntax

If you follow TDD/BDD you'd rather use `expect` instead of `verify`. Which are just an alias functions:

```php
expect("user have 5 posts", $user->getNumPosts())->equals(5);
expect_that($user->isActive());
expect_not($user->isBanned());
```

## Installation

### Installing via Composer

Install composer in a common location or in your project:

```sh
curl -s http://getcomposer.org/installer | php
```

Create the `composer.json` file as follows:

```json
"require-dev": {
    "codeception/verify": "*"
}
```

Run the composer installer:

```sh
php composer.phar install
```

## Usage

Use in any test `verify` function instead of `$this->assert*` methods.

## Extending

`Codeception\Verify` class can be extended with custom assertions. You write your own `verify` function that would instantiate your extended version of Verify class.
