+## Unit Tests
 
+All new features should be 100% code covered, and your pull request should at the very least increase total code overage. 
 
+### Mocks
+To tests results from the API, we keep mock results in SoftLayer/fixtures/<SoftLayer_Service>/ with the method name matching the variable name.
+
+Any call to a service that doesn't have a fixture will result in a TransportError
+
+### Overriding Fixtures
+
+Adding your expected output in the fixtures file with a unique name is a good way to define a fixture that gets used frequently in a test.
+
+```python
+from SoftLayer.fixtures import SoftLayer_Product_Package
+    
+    def test_test(self):
+        amock = self.set_mock('SoftLayer_Product_Package', 'getAllObjects')
+        amock.return_value = fixtures.SoftLayer_Product_Package.RESERVED_CAPACITY
+```
+
+Otherwise defining it on the spot works too.
+```python
+    def test_test(self):
+        mock = self.set_mock('SoftLayer_Network_Storage', 'getObject')
+        mock.return_value = {
+            'billingItem': {'hourlyFlag': True, 'id': 449},
+        }
+```
+
+
+### Call testing
+Testing your code to make sure it makes the correct API call is also very important.
+
+The testing.TestCase class has a method call `assert_called_with` which is pretty handy here.
+
+```python
+self.assert_called_with(
+    'SoftLayer_Billing_Item', # Service
+    'cancelItem',             # Method
+    args=(True, True, ''),    # Args
+    identifier=449,           # Id
+    mask=mock.ANY,            # object Mask,
+    filter=mock.ANY,          # object Filter
+    limit=0,                  # result Limit
+    offset=0                  # result Offset 
+)
+```
+
+Making sure a API was NOT called
+
+```python
+self.assertEqual([], self.calls('SoftLayer_Account', 'getObject'))
+```
+
+Making sure an API call has a specific arg, but you don't want to list out the entire API call (like with a place order test)
+
+```python
+# Get the API Call signature
+order_call = self.calls('SoftLayer_Product_Order', 'placeOrder')
+
+# Get the args property of that API call, which is a tuple, with the first entry being our data.
+order_args = getattr(order_call[0], 'args')[0]
+
+# Test our specific argument value
+self.assertEqual(123, order_args['hostId'])
+```
