 Most of the time you'll only need to use the createMock() method, i.e.:
 
-	$mock = $this->createMock('ORM');
+    $mock = $this->createMock('ORM');
 
 The creation of this mock is performed using best practice defaults. The `__construct` and `__clone` methods of the original class are not executed and the arguments passed to a method of the test double will not be cloned. If these defaults don't match your needs then you can use the `getMockBuilder() ` method to customize the test double generation. Here is a list of methods provided by the Mock Builder:

 ### What is the method we're mocking?
 
 Although we told PHPUnit what methods we want to mock, we haven't actually told it what method these rules we're specifiying apply to.
 You do this by calling `method()` on the returned from `expects()`:
 
-	$mock->expects($matcher)
-		->method($methodName);
+    $mock->expects($matcher)
+        ->method($methodName);
 
 As you can probably guess, `method()` takes one parameter, the name of the method you're mocking.
 There's nothing very fancy about this function.

 The former can be achieved by calling `withAnyParameters()` on the object returned from `method()`.

+        ->method($methodName)

 To only allow specific parameters you can use the `with()` method which accepts any number of parameters.
 The order in which you define the parameters is the order that it expects them to be in when called.
 
-	$mock->expects($matcher)
-		->method($methodName)
-		->with($param1, $param2);
+    $mock->expects($matcher)

 Calling `with()` without any parameters will force the mock method to accept no parameters.

 Ordinarily you could use a foreach loop to iterate over an array of test data, however PHPUnit already can take care of this for us rather easily using "Data Providers". A data provider is a function that returns an array of arguments that can be passed to a test.

 To allow users to selectively run tests you need to organise your tests into groups. Here's an example test showing how to do this:

-	 *
-	 * @group somegroup

+        public function testSomeAnnoyingCase()
+        {
+            // CODE!!
+        }
+    }
 
 Our convention is to use lowercase group names, with more specific levels in a group separated by periods. For example, the Validate helper tests are part of the following groups:
 
-	kohana
-	kohana.validation
-	kohana.validation.helpers
+    kohana
+    kohana.validation
+    kohana.validation.helpers
 
 To actually limit your testing to the "somegroup" group, use:
 
-	$ phpunit --boostrap=modules/unittest/bootstrap.php --group=somegroup modules/unittest/tests.php
+    $ phpunit --boostrap=modules/unittest/bootstrap.php --group=somegroup modules/unittest/tests.php
 
 This functionality can be used to record which bug reports a test is for:
 
-	/**
-	 *
-	 * @group bugs.1477
-	 */
-	function testAccountCannotGoBelowZero()
-	{
-		// Some arbitary code
-	}
+    /**
+     *
+     * @group bugs.1477
+     */
+    function testAccountCannotGoBelowZero()
+    {
+        // Some arbitary code
+    }
 
 To see all groups that are available in your code run:
 
-	$ phpunit --boostrap=modules/unittest/bootstrap.php --list-groups modules/unittest/tests.php
+    $ phpunit --boostrap=modules/unittest/bootstrap.php --list-groups modules/unittest/tests.php
 
 *Note:* The `--list-groups` switch should appear before the path to the test suite loader.
 
 You can also exclude groups while testing using the `--exclude-group` switch. This can be useful if you want to ignore all kohana tests:
 
-	$ phpunit --bootstrap=modules/unittest/bootstrap.php --exclude-group=kohana modules/unittest/tests.php
+    $ phpunit --bootstrap=modules/unittest/bootstrap.php --exclude-group=kohana modules/unittest/tests.php
