+This is a class to extend for testing an LRS inside a LL instance. Any tests that depend on an LRS being created before testing should utilise this class.
+
+### StatementsTestCase (extends LrsTestCase)
+This is a class to extend for testing retrieval of statements inside an LRS. Any tests that depend on a statements being created before or during testing should utilise this class.
+
+## Directories
+### fixtures
+This directory should contain any files required by the tests.
+
+### repos
+This directory should contain tests for repositories (data in, data out).
+
+### routes
+This directory should contain tests for routes (request in, response out). Inside this directory there is a RouteTestTrait that should be used by all classes inside this directory for sending requests.
