# Moto - Mock AWS Services

## Install
```console
$ pip install 'moto[ec2,s3,all]'
```
## In a nutshell
Moto is a library that allows your tests to easily mock out AWS Services.
Imagine you have the following python code that you want to test:
```python
import boto3
class MyModel(object):
def __init__(self, name, value):
self.name = name
self.value = value
def save(self):
s3 = boto3.client('s3', region_name='us-east-1')
s3.put_object(Bucket='mybucket', Key=self.name, Body=self.value)
```
Take a minute to think how you would have tested that in the past.
Now see how you could test it with Moto:
```python
import boto3
from moto import mock_s3
from mymodule import MyModel
@mock_s3
def test_my_model_save():
conn = boto3.resource('s3', region_name='us-east-1')
# We need to create the bucket since this is all in Moto's 'virtual' AWS account
conn.create_bucket(Bucket='mybucket')
model_instance = MyModel('steve', 'is awesome')
model_instance.save()
body = conn.Object('mybucket', 'steve').get()['Body'].read().decode("utf-8")
assert body == 'is awesome'
```
With the decorator wrapping the test, all the calls to s3 are automatically mocked out. The mock keeps the state of the buckets and keys.
For a full list of which services and features are covered, please see our [implementation coverage](https://github.com/spulec/moto/blob/master/IMPLEMENTATION_COVERAGE.md).
