+<p>This section describes how to write tests for the provider drivers and how to use
+our fixture framework and system for mocking the responses.</p>
+<p>Examples in this section refer to the compute API but things described in this
+section are also applicable to other APIs.</p>
+<ul>
+<li><a href="#creating-fixtures">Creating Fixtures</a></li>
+<li><a href="#mocking-responses-and-using-mockhttp-class">Mocking responses and using MockHttp class</a></li>
+<li><a href="#mock-http-class-example">MockHttp class example</a></li>
+</ul>
+<h3 id="creating-fixtures">Creating Fixtures</h3>
+
+<p>In our test cases fixtures store different responses returned by the provider APIs.
+They are stored and named in the following format:
+<code>test/<api name>/fixtures/<provider name>/<fixture name></code>.</p>
+<p>Fixtures are usually generated by "manually" performing (usually using a tool like curl)
+different actions with the provider API and saving responses in the files.</p>
+<p><em>Note: You are advised against using the examples from the provider API docs because empirical
+evidence has shown that in a lot of cases they are wrong or out of date.</em></p>
+<h3 id="mocking-responses-and-using-mockhttp-class">Mocking responses and using MockHttp class</h3>
+
+<p>Each provider test file usually contains a class which inherits from the base <code>MockHttp</code> class.
+This class is responsible for loading fixtures and returning a mocked response for
+each API call.</p>
+<p>Which method is called is primary determined by the requested path. All the forward slashes,
+periods and dashes in the requested path are replaced by an underscore (<code>_</code>).</p>
+<p>Some examples:</p>
+<p><strong>Requested path</strong>: <code>/servers/list.all</code><br />
+<strong>use_params</strong>: <code>MockHttp.use_params = None</code><br />
+<strong>Name of the method on the Mock class</strong>: <code>_servers_list_all</code></p>
+<p><strong>Requested path</strong>: <code>/servers/reboot-all</code><br />
+<strong>use_params</strong>: <code>MockHttp.use_params = None</code><br />
+<strong>Name of the method on the Mock class</strong>: <code>_servers_reboot_all</code></p>
+<p>Some providers use the same path for all the requests and the actual action is determined by
+some parameter in a query string. To overcome this problem, set the <code>use_param</code> MockHttp class
+attribute to the name of the query string parameter which specifies the action.
+Good example of a provider API which does this is the Amazon EC2 API
+(<code>test/compute/test_ec2.py</code>).</p>
+<p>Example:</p>
+<p><strong>Requested path</strong>: <code>/?Action=RebootInstances&InstanceId=12345</code><br />
+<strong>use_params</strong>: <code>MockHttp.use_params = 'Action'</code><br />
+<strong>Name of the method on the Mock class</strong>: <code>_RebootInstances</code></p>
+<p>Usually we also want to test different scenarios for a single API call.
+Good example of this is testing a success and different failure scenarios when creating a node.
+Because we are testing a single API call, this means that the request path will in most
+cases be the same. This makes loading a different response fixture for each API call
+without inspecting the request parameters or doing something similar very cumbersome.</p>
+<p>This problem can be overcome by setting the <code>type</code> attribute on the <code>MockHttp</code> class before
+issuing a request. The specified <code>type</code> will be automatically appended to the end of the
+constructed method name.</p>
+<p>Example:</p>
+<p><strong>Requested path</strong>: <code>/servers/reboot-all</code><br />
+<strong>use_params</strong>: <code>MockHttp.use_params = None</code><br />
+<strong>type</strong>: <code>MockHttp.type = 'FAILURE'</code><br />
+<strong>Name of the method on the Mock class</strong>: <code>_servers_reboot_all_FAILURE</code></p>
+<h3 id="mock-http-class-example">MockHttp class example</h3>
+
+<p>Bellow is an example of a MockHttp class from the Amazon EC2 tests with a
+single method.</p>
+<p>Return value of a mock method is a tuple -
+<strong>(status_code, response_body, response_headers, response_status_string)</strong>.</p>
+<ul>
