+# Prophecy
+
+[![Stable release](https://poser.pugx.org/phpspec/prophecy/version.svg)](https://packagist.org/packages/phpspec/prophecy)
+[![Build Status](https://travis-ci.org/phpspec/prophecy.svg?branch=master)](https://travis-ci.org/phpspec/prophecy)
+
+Prophecy is a highly opinionated yet very powerful and flexible PHP object mocking
+framework. Though initially it was created to fulfil phpspec2 needs, it is flexible
+enough to be used inside any testing framework out there with minimal effort.
+
+## A simple example
+
+```php
+<?php
+
+class UserTest extends PHPUnit_Framework_TestCase
+{
+    private $prophet;
+
+    public function testPasswordHashing()
+    {
+        $hasher = $this->prophet->prophesize('App\Security\Hasher');
+        $user   = new App\Entity\User($hasher->reveal());
+
+        $hasher->generateHash($user, 'qwerty')->willReturn('hashed_pass');
+
+        $user->setPassword('qwerty');
+
+        $this->assertEquals('hashed_pass', $user->getPassword());
+    }
+
+    protected function setup()
+    {
+        $this->prophet = new \Prophecy\Prophet;
+    }
+
+    protected function tearDown()
+    {
+        $this->prophet->checkPredictions();
+    }
+}
+```
+
+## Installation
+
+### Prerequisites
+
+Prophecy requires PHP 5.3.3 or greater.
+
+### Setup through composer
+
+First, add Prophecy to the list of dependencies inside your `composer.json`:
+
+```json
+{
+    "require-dev": {
+        "phpspec/prophecy": "~1.0"
+    }
+}
+```
+
+Then simply install it with composer:
+
+```bash
+$> composer install --prefer-dist
+```
+
+You can read more about Composer on its [official webpage](http://getcomposer.org).
+
+## How to use it
+
+First of all, in Prophecy every word has a logical meaning, even the name of the library
+itself (Prophecy). When you start feeling that, you'll become very fluid with this
+tool.
+
+For example, Prophecy has been named that way because it concentrates on describing the future
+behavior of objects with very limited knowledge about them. But as with any other prophecy,
+those object prophecies can't create themselves - there should be a Prophet:
+
+```php
+$prophet = new Prophecy\Prophet;
+```
+
+The Prophet creates prophecies by *prophesizing* them:
+
+```php
+$prophecy = $prophet->prophesize();
+```
+
+The result of the `prophesize()` method call is a new object of class `ObjectProphecy`. Yes,
+that's your specific object prophecy, which describes how your object would behave
+in the near future. But first, you need to specify which object you're talking about,
+right?
+
+```php
+$prophecy->willExtend('stdClass');
+$prophecy->willImplement('SessionHandlerInterface');
+```
+
+There are 2 interesting calls - `willExtend` and `willImplement`. The first one tells
+object prophecy that our object should extend specific class, the second one says that
+it should implement some interface. Obviously, objects in PHP can implement multiple
+interfaces, but extend only one parent class.
+
+### Dummies
+
+Ok, now we have our object prophecy. What can we do with it? First of all, we can get
+our object *dummy* by revealing its prophecy:
+
+```php
+$dummy = $prophecy->reveal();
+```
+
+The `$dummy` variable now holds a special dummy object. Dummy objects are objects that extend
+and/or implement preset classes/interfaces by overriding all their public methods. The key
+point about dummies is that they do not hold any logic - they just do nothing. Any method
+of the dummy will always return `null` and the dummy will never throw any exceptions.
+Dummy is your friend if you don't care about the actual behavior of this double and just need
+a token object to satisfy a method typehint.
+
+You need to understand one thing - a dummy is not a prophecy. Your object prophecy is still
+assigned to `$prophecy` variable and in order to manipulate with your expectations, you
+should work with it. `$dummy` is a dummy - a simple php object that tries to fulfil your
+prophecy.
+
+### Stubs
+
+Ok, now we know how to create basic prophecies and reveal dummies from them. That's
+awesome if we don't care about our _doubles_ (objects that reflect originals)
+interactions. If we do, we need to use *stubs* or *mocks*.
+
+A stub is an object double, which doesn't have any expectations about the object behavior,
+but when put in specific environment, behaves in specific way. Ok, I know, it's cryptic,
+but bear with me for a minute. Simply put, a stub is a dummy, which depending on the called
+method signature does different things (has logic). To create stubs in Prophecy:
+
+```php
+$prophecy->read('123')->willReturn('value');
+```
+
+Oh wow. We've just made an arbitrary call on the object prophecy? Yes, we did. And this
+call returned us a new object instance of class `MethodProphecy`. Yep, that's a specific
+method with arguments prophecy. Method prophecies give you the ability to create method
+promises or predictions. We'll talk about method predictions later in the _Mocks_ section.
+
+#### Promises
+
+Promises are logical blocks, that represent your fictional methods in prophecy terms
+and they are handled by the `MethodProphecy::will(PromiseInterface $promise)` method.
+As a matter of fact, the call that we made earlier (`willReturn('value')`) is a simple
+shortcut to:
+
+```php
+$prophecy->read('123')->will(new Prophecy\Promise\ReturnPromise(array('value')));
+```
+
+This promise will cause any call to our double's `read()` method with exactly one
+argument - `'123'` to always return `'value'`. But that's only for this
+promise, there's plenty others you can use:
+
+- `ReturnPromise` or `->willReturn(1)` - returns a value from a method call
+- `ReturnArgumentPromise` or `->willReturnArgument($index)` - returns the nth method argument from call
+- `ThrowPromise` or `->willThrow($exception)` - causes the method to throw specific exception
+- `CallbackPromise` or `->will($callback)` - gives you a quick way to define your own custom logic
+
+Keep in mind, that you can always add even more promises by implementing
+`Prophecy\Promise\PromiseInterface`.
+
+#### Method prophecies idempotency
+
+Prophecy enforces same method prophecies and, as a consequence, same promises and
+predictions for the same method calls with the same arguments. This means:
+
+```php
+$methodProphecy1 = $prophecy->read('123');
+$methodProphecy2 = $prophecy->read('123');
+$methodProphecy3 = $prophecy->read('321');
+
+$methodProphecy1 === $methodProphecy2;
+$methodProphecy1 !== $methodProphecy3;
+```
+
+That's interesting, right? Now you might ask me how would you define more complex
+behaviors where some method call changes behavior of others. In PHPUnit or Mockery
+you do that by predicting how many times your method will be called. In Prophecy,
+you'll use promises for that:
+
+```php
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName('everzet')->will(function () {
+    $this->getName()->willReturn('everzet');
+});
+
+// For PHP 5.3
+$user->setName('everzet')->will(function ($args, $user) {
+    $user->getName()->willReturn('everzet');
+});
+
+// Or
+$user->setName('everzet')->will(function ($args) use ($user) {
+    $user->getName()->willReturn('everzet');
+});
+```
+
+And now it doesn't matter how many times or in which order your methods are called.
+What matters is their behaviors and how well you faked it.
+
+#### Arguments wildcarding
+
+The previous example is awesome (at least I hope it is for you), but that's not
+optimal enough. We hardcoded `'everzet'` in our expectation. Isn't there a better
+way? In fact there is, but it involves understanding what this `'everzet'`
+actually is.
+
+You see, even if method arguments used during method prophecy creation look
+like simple method arguments, in reality they are not. They are argument token
+wildcards.  As a matter of fact, `->setName('everzet')` looks like a simple call just
+because Prophecy automatically transforms it under the hood into:
+
+```php
+$user->setName(new Prophecy\Argument\Token\ExactValueToken('everzet'));
+```
+
+Those argument tokens are simple PHP classes, that implement
+`Prophecy\Argument\Token\TokenInterface` and tell Prophecy how to compare real arguments
+with your expectations. And yes, those classnames are damn big. That's why there's a
+shortcut class `Prophecy\Argument`, which you can use to create tokens like that:
+
+```php
+use Prophecy\Argument;
+
+$user->setName(Argument::exact('everzet'));
+```
+
+`ExactValueToken` is not very useful in our case as it forced us to hardcode the username.
+That's why Prophecy comes bundled with a bunch of other tokens:
+
+- `IdenticalValueToken` or `Argument::is($value)` - checks that the argument is identical to a specific value
+- `ExactValueToken` or `Argument::exact($value)` - checks that the argument matches a specific value
+- `TypeToken` or `Argument::type($typeOrClass)` - checks that the argument matches a specific type or
+  classname
+- `ObjectStateToken` or `Argument::which($method, $value)` - checks that the argument method returns
+  a specific value
+- `CallbackToken` or `Argument::that(callback)` - checks that the argument matches a custom callback
+- `AnyValueToken` or `Argument::any()` - matches any argument
+- `AnyValuesToken` or `Argument::cetera()` - matches any arguments to the rest of the signature
+- `StringContainsToken` or `Argument::containingString($value)` - checks that the argument contains a specific string value
+
+And you can add even more by implementing `TokenInterface` with your own custom classes.
+
+So, let's refactor our initial `{set,get}Name()` logic with argument tokens:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+```
+
+That's it. Now our `{set,get}Name()` prophecy will work with any string argument provided to it.
+We've just described how our stub object should behave, even though the original object could have
+no behavior whatsoever.
+
+One last bit about arguments now. You might ask, what happens in case of:
+
+```php
+use Prophecy\Argument;
+
+$user->getName()->willReturn(null);
+
+// For PHP 5.4
+$user->setName(Argument::type('string'))->will(function ($args) {
+    $this->getName()->willReturn($args[0]);
+});
+
+// For PHP 5.3
+$user->setName(Argument::type('string'))->will(function ($args, $user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+// Or
+$user->setName(Argument::type('string'))->will(function ($args) use ($user) {
+    $user->getName()->willReturn($args[0]);
+});
+
+$user->setName(Argument::any())->will(function () {
+});
+```
+
+Nothing. Your stub will continue behaving the way it did before. That's because of how
+arguments wildcarding works. Every argument token type has a different score level, which
+wildcard then uses to calculate the final arguments match score and use the method prophecy
+promise that has the highest score. In this case, `Argument::type()` in case of success
+scores `5` and `Argument::any()` scores `3`. So the type token wins, as does the first
+`setName()` method prophecy and its promise. The simple rule of thumb - more precise token
+always wins.
+
+#### Getting stub objects
+
+Ok, now we know how to define our prophecy method promises, let's get our stub from
+it:
+
+```php
+$stub = $prophecy->reveal();
+```
+
+As you might see, the only difference between how we get dummies and stubs is that with
+stubs we describe every object conversation instead of just agreeing with `null` returns
+(object being *dummy*). As a matter of fact, after you define your first promise
+(method call), Prophecy will force you to define all the communications - it throws
+the `UnexpectedCallException` for any call you didn't describe with object prophecy before
+calling it on a stub.
+
+### Mocks
+
+Now we know how to define doubles without behavior (dummies) and doubles with behavior, but
+no expectations (stubs). What's left is doubles for which we have some expectations. These
+are called mocks and in Prophecy they look almost exactly the same as stubs, except that
+they define *predictions* instead of *promises* on method prophecies:
+
+```php
+$entityManager->flush()->shouldBeCalled();
+```
+
+#### Predictions
+
+The `shouldBeCalled()` method here assigns `CallPrediction` to our method prophecy.
+Predictions are a delayed behavior check for your prophecies. You see, during the entire lifetime
+of your doubles, Prophecy records every single call you're making against it inside your
+code. After that, Prophecy can use this collected information to check if it matches defined
+predictions. You can assign predictions to method prophecies using the
+`MethodProphecy::should(PredictionInterface $prediction)` method. As a matter of fact,
+the `shouldBeCalled()` method we used earlier is just a shortcut to:
+
+```php
+$entityManager->flush()->should(new Prophecy\Prediction\CallPrediction());
+```
+
+It checks if your method of interest (that matches both the method name and the arguments wildcard)
+was called 1 or more times. If the prediction failed then it throws an exception. When does this
+check happen? Whenever you call `checkPredictions()` on the main Prophet object:
+
+```php
+$prophet->checkPredictions();
+```
+
+In PHPUnit, you would want to put this call into the `tearDown()` method. If no predictions
+are defined, it would do nothing. So it won't harm to call it after every test.
+
+There are plenty more predictions you can play with:
+
+- `CallPrediction` or `shouldBeCalled()` - checks that the method has been called 1 or more times
+- `NoCallsPrediction` or `shouldNotBeCalled()` - checks that the method has not been called
+- `CallTimesPrediction` or `shouldBeCalledTimes($count)` - checks that the method has been called
+  `$count` times
+- `CallbackPrediction` or `should($callback)` - checks the method against your own custom callback
+
+Of course, you can always create your own custom prediction any time by implementing
+`PredictionInterface`.
+
+### Spies
+
+The last bit of awesomeness in Prophecy is out-of-the-box spies support. As I said in the previous
+section, Prophecy records every call made during the double's entire lifetime. This means
+you don't need to record predictions in order to check them. You can also do it
+manually by using the `MethodProphecy::shouldHave(PredictionInterface $prediction)` method:
+
+```php
+$em = $prophet->prophesize('Doctrine\ORM\EntityManager');
+
+$controller->createUser($em->reveal());
+
+$em->flush()->shouldHaveBeenCalled();
+```
