-#  How To Create a SilverStripe Test
-
-A unit test class will test the behaviour of one of your `[api:DataObjects]`.  This simple fragment of `[api:SiteTreeTest]`
-provides us the basics of creating unit tests.

-	<?php
-	class SiteTreeTest extends SapphireTest {
-		
-		// Define the fixture file to use for this test class
-		private static $fixture_file = 'SiteTreeTest.yml';

-		 *  - Turns things into lowercase-hyphen-format
-		 *  - Generates from Title by default, unless URLSegment is explicitly set
-		 *  - Resolves duplicates by appending a number
-		 */
-		public function testURLGeneration() {
-			$expectedURLs = array(
-				'home' => 'home',
-				'staff' => 'my-staff',
-				'about' => 'about-us',
-				'staffduplicate' => 'my-staff-2',
-				'product1' => '1-1-test-product',
-				'product2' => 'another-product',
-				'product3' => 'another-product-2',
-				'product4' => 'another-product-3',
-			);
-			
-			foreach($expectedURLs as $fixture => $urlSegment) {
-				$obj = $this->objFromFixture('Page', $fixture);
-				$this->assertEquals($urlSegment, $obj->URLSegment);
-			}
-		}
-	}
-	
-
-
-There are a number of points to note in this code fragment:
-
-*  Your test is a **subclass of SapphireTest**.  Both unit tests and functional tests are a subclass of `[api:SapphireTest]`.
-*  **static $fixture_file** is defined.  The testing framework will automatically set up a new database for **each** of
-your tests.  The initial database content will be sourced from the YML file that you list in $fixture_file. The property can take an array of fixture paths.
-*  Each **method that starts with the word "test"** will be executed by the TestRunner.  Define as many as you like; the
-database will be rebuilt for each of these.
-*  **$this->objFromFixture($className, $identifier)** can be used to select one of the objects named in your fixture
-file.  To identify to the object, we provide a class name and an identifier.  The identifier is specified in the YML
-file but not saved in the database anywhere.  objFromFixture() looks the `[api:DataObject]` up in memory rather than using the
-database.  This means that you can use it to test the functions responsible for looking up content in the database.
-
-## Assertion commands
-
-**$this->assertEquals()** is an example of an assertion function.  
-These functions form the basis of our tests - a test
-fails if and only if one or more of the assertions fail.  
-See [the PHPUnit manual](http://www.phpunit.de/manual/current/en/api.html#api.assert)
-for a listing of all PHPUnit's built-in assertions.
-
-The `[api:SapphireTest]` class comes with additional assertions which are more
-specific to the framework, e.g. `[assertEmailSent](api:SapphireTest->assertEmailSent())`
-which can simulate sending emails through the `Email->send()` API without actually
-using a mail server (see the [testing emails](email-sending)) guide.
-
-## Fixtures
-
-Often you need to test your functionality with some existing data, so called "fixtures".
-These records are inserted on a fresh test database automatically.

+# Creating a SilverStripe Test
+
+A test is created by extending one of two classes, SapphireTest and FunctionalTest. You would subclass SapphireTest to
+test your application logic, for example testing the behaviour of one of your `[api:DataObjects]`, whereas FunctionalTest
+is extended when you want to test your application's functionality, such as testing the results of GET and POST requests,
+and validating the content of a page. `[api:FunctionalTest]` is a subclass of `[api:SapphireTest]`.
+
+## Creating a test from SapphireTest
+
+Here is an example of a test which extends SapphireTest:
+
+	:::php
+	<?php
+	class SiteTreeTest extends SapphireTest {
+
+		// Define the fixture file to use for this test class
+		private static $fixture_file = 'SiteTreeTest.yml';
+
+		/**
+		 * Test generation of the URLSegment values.
+		 *  - Turns things into lowercase-hyphen-format
+		 *  - Generates from Title by default, unless URLSegment is explicitly set
+		 *  - Resolves duplicates by appending a number
+		 */
+		public function testURLGeneration() {
+			$expectedURLs = array(
+				'home' => 'home',
+				'staff' => 'my-staff',
+				'about' => 'about-us',
+				'staffduplicate' => 'my-staff-2',
+				'product1' => '1-1-test-product',
+				'product2' => 'another-product',
+				'product3' => 'another-product-2',
+				'product4' => 'another-product-3',
+			);
+
+			foreach($expectedURLs as $fixture => $urlSegment) {
+				$obj = $this->objFromFixture('Page', $fixture);
+				$this->assertEquals($urlSegment, $obj->URLSegment);
+			}
+		}
+	}
+
+Firstly we define a static member `$fixture_file`, this should point to a file that represents the data we want to test,
+represented in YAML. When our test is run, the data from this file will be loaded into a test database for our test to use.
+This property can be an array of strings pointing to many .yml files, but for our test we are just using a string on its
+own. For more detail on fixtures, see the [page on fixtures](fixtures).
+
+The second part of our class is the `testURLGeneration` method. This method is our test. You can asign many tests, but
+again for our purposes there is just the one. When the test is executed, methods prefixed with the word **test** will be
+run. The test database is rebuilt everytime one of these methods is run.
+
+Inside our test method is the `objFromFixture` method that will generate an object for us based on data from our fixture
+file. To identify to the object, we provide a class name and an identifier. The identifier is specified in the YAML file
+but not saved in the database anywhere, `objFromFixture` looks the `[api:DataObject]` up in memory rather than using the
+database. This means that you can use it to test the functions responsible for looking up content in the database.
+
+The final part of our test is an assertion command, `assertEquals`. An assertion command allows us to test for something
+in our test methods (in this case we are testing if two values are equal). A test method can have more than one assertion
+command, and if anyone of these tests fail, then the whole test method will fail.
+
+For more information on PHPUnit's assertions see the [PHPUnit manual](http://www.phpunit.de/manual/current/en/api.html#api.assert).
+
+The `[api:SapphireTest]` class comes with additional assertions which are more specific to the Sapphire, for example the
+`[assertEmailSent](api:SapphireTest->assertEmailSent())` method, which simulates sending emails through the `Email->send()`
+API without actually using a mail server. For more details on this see th [testing emails](testing-email)) guide.

+# Glossary
+
+**Assertion:** A predicate statement that must be true when a test runs.
+
+**Behat:** A behaviour-driven testing library used with SilverStripe as a higher-level
+alternative to the `FunctionalTest` API, see [http://behat.org](http://behat.org).
+
+**Test Case:** The atomic class type in most unit test frameworks. New unit tests are created by inheriting from the
+base test case.
+
+**Test Suite:** Also known as a 'test group', a composite of test cases, used to collect individual unit tests into
+packages, allowing all tests to be run at once.
+
+**Fixture:** Usually refers to the runtime context of a unit test - the environment and data prerequisites that must be
+in place in order to run the test and expect a particular outcome. Most unit test frameworks provide methods that can be
+used to create fixtures for the duration of a test - `setUp` - and clean them up after the test is done - `tearDown'.
+
+**Refactoring:** A behavior preserving transformation of code. If you change the code, while keeping the actual
+functionality the same, it is refactoring. If you change the behavior or add new functionality it's not.
+
+**Smell:** A code smell is a symptom of a problem. Usually refers to code that is structured in a way that will lead to
+problems with maintenance or understanding.
+
+**Spike:** A limited and throwaway sketch of code or experiment to get a feel for how long it will take to implement a
+certain feature, or a possible direction for how that feature might work.
+
+**Test Double:** Also known as a 'Substitute'. A general term for a dummy object that replaces a real object with the
+same interface. Substituting objects is useful when a real object is difficult or impossible to incorporate into a unit
+test.
+
+**Fake Object**: A substitute object that simply replaces a real object with the same interface, and returns a
+pre-determined (usually fixed) value from each method.
+
+**Mock Object:** A substitute object that mimicks the same behavior as a real object (some people think of mocks as
+"crash test dummy" objects). Mocks differ from other kinds of substitute objects in that they must understand the
+context of each call to them, setting expectations of which, and what order, methods will be invoked and what parameters
+will be passed.
+
+**Test-Driven Development (TDD):** A style of programming where tests for a new feature are constructed before any code
+is written. Code to implement the feature is then written with the aim of making the tests pass. Testing is used to
+understand the problem space and discover suitable APIs for performing specific actions.
+
+**Behavior Driven Development (BDD):** An extension of the test-driven programming style, where tests are used primarily
+for describing the specification of how code should perform. In practice, there's little or no technical difference - it
+all comes down to language. In BDD, the usual terminology is changed to reflect this change of focus, so *Specification*
+is used in place of *Test Case*, and *should* is used in place of *expect* and *assert*.

-for describing the specification of how code should perform. In practice, there's little or no technical difference - it
-all comes down to language. In BDD, the usual terminology is changed to reflect this change of focus, so *Specification*
-is used in place of *Test Case*, and *should* is used in place of *expect* and *assert*.
