+## Code example
+
+Let's say you have a prod code snippet like this one:
+
+```python
+import elasticsearch
+
+class FooService:
+
+    def __init__(self):
+        self.es = elasticsearch.Elasticsearch(hosts=[{'host': 'localhost', 'port': 9200}])
+
+    def create(self, index, body):
+        es_object = self.es.index(index, body)
+        return es_object.get('_id')
+
+    def read(self, index, id):
+        es_object = self.es.get(index, id)
+        return es_object.get('_source')
+
+```
+
+Than you should be able to test this class by mocking ElasticSearch using the following test class:
+
+```python
+from unittest import TestCase
+from elasticmock import elasticmock
+from foo.bar import FooService
+
+class FooServiceTest(TestCase):
+
+    @elasticmock
+    def should_create_and_read_object(self):
+        # Variables used to test
+        index = 'test-index'
+        expected_document = {
+            'foo': 'bar'
+        }
+
+        # Instantiate service
+        service = FooService()
+
+        # Index document on ElasticSearch
+        id = service.create(index, expected_document)
+        self.assertIsNotNone(id)
+
+        # Retrive dpcument from ElasticSearch
+        document = service.read(index, id)
+        self.assertEquals(expected_document, document)
+
+```
+
 ## Notes:
 
 - The mocked **search** method returns **all available documents** indexed on the index with the requested document type.
