Quick Examples
==============

Create a mock object to return a sequence of values from a set of method
calls.

.. code-block:: php

class SimpleTest extends PHPUnit_Framework_TestCase
    {

public function tearDown()
        {
            \Mockery::close();
        }

public function testSimpleMock()
        {
            $mock = \Mockery::mock(array('pi' => 3.1416, 'e' => 2.71));
            $this->assertEquals(3.1416, $mock->pi());
            $this->assertEquals(2.71, $mock->e());
        }

}

Create a mock object which returns a self-chaining Undefined object for a
method call.

.. code-block:: php

use \Mockery as m;

class UndefinedTest extends PHPUnit_Framework_TestCase
    {

public function tearDown()
        {
            m::close();
        }

public function testUndefinedValues()
        {
            $mock = m::mock('mymock');
            $mock->shouldReceive('divideBy')->with(0)->andReturnUndefined();
            $this->assertTrue($mock->divideBy(0) instanceof \Mockery\Undefined);
        }

}

Creates a mock object which multiple query calls and a single update call.

.. code-block:: php

use \Mockery as m;

class DbTest extends PHPUnit_Framework_TestCase
    {

public function tearDown()
        {
            m::close();
        }

public function testDbAdapter()
        {
            $mock = m::mock('db');
            $mock->shouldReceive('query')->andReturn(1, 2, 3);
            $mock->shouldReceive('update')->with(5)->andReturn(NULL)->once();

// ... test code here using the mock
        }

}

Expect all queries to be executed before any updates.

.. code-block:: php

use \Mockery as m;

class DbTest extends PHPUnit_Framework_TestCase
    {

public function tearDown()
        {
            m::close();
        }

public function testQueryAndUpdateOrder()
        {
            $mock = m::mock('db');
            $mock->shouldReceive('query')->andReturn(1, 2, 3)->ordered();
            $mock->shouldReceive('update')->andReturn(NULL)->once()->ordered();

// ... test code here using the mock
        }

}

Create a mock object where all queries occur after startup, but before finish,
and where queries are expected with several different params.

.. code-block:: php

use \Mockery as m;

class DbTest extends PHPUnit_Framework_TestCase
    {

public function tearDown()
        {
            m::close();
        }

public function testOrderedQueries()
        {
            $db = m::mock('db');
            $db->shouldReceive('startup')->once()->ordered();
            $db->shouldReceive('query')->with('CPWR')->andReturn(12.3)->once()->ordered('queries');
            $db->shouldReceive('query')->with('MSFT')->andReturn(10.0)->once()->ordered('queries');
            $db->shouldReceive('query')->with("/^....$/")->andReturn(3.3)->atLeast()->once()->ordered('queries');
            $db->shouldReceive('finish')->once()->ordered();

// ... test code here using the mock
        }

}
