## 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:
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_aws
from mymodule import MyModel
@mock_aws
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 track of the state of the buckets and keys.
