+# AWS Config Querying Support in Moto
+
+An experimental feature for AWS Config has been developed to provide AWS Config capabilities in your unit tests. 
+This feature is experimental as there are many services that are not yet supported and will require the community to add them in
+over time. This page details how the feature works and how you can use it.
+
+## What is this and why would I use this?
+
+AWS Config is an AWS service that describes your AWS resource types and can track their changes over time. At this time, moto does not
+have support for handling the configuration history changes, but it does have a few methods mocked out that can be immensely useful 
+for unit testing.
+
+If you are developing automation that needs to pull against AWS Config, then this will help you write tests that can simulate your
+code in production.
+
+## How does this work?
+
+The AWS Config capabilities in moto work by examining the state of resources that are created within moto, and then returning that data
+in the way that AWS Config would return it (sans history). This will work by querying all of the moto backends (regions) for a given
+resource type.
+
+However, this will only work on resource types that have this enabled.
+
+### Current enabled resource types:
+
+1. S3
+
+
+## Developer Guide
+
+There are several pieces to this for adding new capabilities to moto:
+
+1. Listing resources
+1. Describing resources
+
+For both, there are a number of pre-requisites:
+
+### Base Components
+
+In the `moto/core/models.py` file is a class named `ConfigQueryModel`. This is a base class that keeps track of all the 
+resource type backends.
+
+At a minimum, resource types that have this enabled will have:
+
+1. A `config.py` file that will import the resource type backends (from the `__init__.py`)
+1. In the resource's `config.py`, an implementation of the `ConfigQueryModel` class with logic unique to the resource type
+1. An instantiation of the `ConfigQueryModel`
+1. In the `moto/config/models.py` file, import the `ConfigQueryModel` instantiation, and update `RESOURCE_MAP` to have a mapping of the AWS Config resource type
+ to the instantiation on the previous step (just imported).
+   
+An example of the above is implemented for S3. You can see that by looking at:
+
+1. `moto/s3/config.py`
+1. `moto/config/models.py`
+
+As well as the corresponding unit tests in:
+
+1. `tests/s3/test_s3.py`
+1. `tests/config/test_config.py`
+
+Note for unit testing, you will want to add a test to ensure that you can query all the resources effectively. For testing this feature,
+the unit tests for the `ConfigQueryModel` will not make use of `boto` to create resources, such as S3 buckets. You will need to use the 
+backend model methods to provision the resources. This is to make tests compatible with the moto server. You should absolutely make tests
+in the resource type to test listing and object fetching.
+
+### Listing
+S3 is currently the model implementation, but it also odd in that S3 is a global resource type with regional resource residency.
+
+But for most resource types the following is true:
+
+1. There are regional backends with their own sets of data
+1. Config aggregation can pull data from any backend region -- we assume that everything lives in the same account
+
+Implementing the listing capability will be different for each resource type. At a minimum, you will need to return a `List` of `Dict`s
+that look like this:
+
+```python
+ [
+    {
+        'type': 'AWS::The AWS Config data type',
+        'name': 'The name of the resource',
+        'id': 'The ID of the resource',
+        'region': 'The region of the resource -- if global, then you may want to have the calling logic pass in the
+                   aggregator region in for the resource region -- or just us-east-1 :P'
+    }
+    , ...
+]
+```
+
+It's recommended to read the comment for the `ConfigQueryModel`'s `list_config_service_resources` function in [base class here](moto/core/models.py).
+
+^^ The AWS Config code will see this and format it correct for both aggregated and non-aggregated calls.
+
+#### General implementation tips
+The aggregation and non-aggregation querying can and should just use the same overall logic. The differences are:
+
+1. Non-aggregated listing will specify the region-name of the resource backend `backend_region`
+1. Aggregated listing will need to be able to list resource types across ALL backends and filter optionally by passing in `resource_region`.
+
+An example of a working implementation of this is [S3](moto/s3/config.py).
+
+Pagination should generally be able to pull out the resource across any region so should be sharded by `region-item-name` -- not done for S3
+because S3 has a globally unique name space.
+
+### Describing Resources
+Fetching a resource's configuration has some similarities to listing resources, but it requires more work (to implement). Due to the
+various ways that a resource can be configured, some work will need to be done to ensure that the Config dict returned is correct.
+
+For most resource types the following is true:
+
+1. There are regional backends with their own sets of data
+1. Config aggregation can pull data from any backend region -- we assume that everything lives in the same account
+
+The current implementation is for S3. S3 is very complex and depending on how the bucket is configured will depend on what Config will
+return for it.
+
+When implementing resource config fetching, you will need to return at a minimum `None` if the resource is not found, or a `dict` that looks
+like what AWS Config would return.
+
+It's recommended to read the comment for the `ConfigQueryModel` 's `get_config_resource` function in [base class here](moto/core/models.py).

+## IAM-like Access Control
+
+Moto also has the ability to authenticate and authorize actions, just like it's done by IAM in AWS. This functionality can be enabled by either setting the `INITIAL_NO_AUTH_ACTION_COUNT` environment variable or using the `set_initial_no_auth_action_count` decorator. Note that the current implementation is very basic, see [this file](https://github.com/spulec/moto/blob/master/moto/core/access_control.py) for more information.
+
+### `INITIAL_NO_AUTH_ACTION_COUNT`
+
+If this environment variable is set, moto will skip performing any authentication as many times as the variable's value, and only starts authenticating requests afterwards. If it is not set, it defaults to infinity, thus moto will never perform any authentication at all.
+
+### `set_initial_no_auth_action_count`
+
+This is a decorator that works similarly to the environment variable, but the settings are only valid in the function's scope. When the function returns, everything is restored.
+
+```python
+@set_initial_no_auth_action_count(4)
+@mock_ec2
+def test_describe_instances_allowed():
+    policy_document = {
+        "Version": "2012-10-17",
+        "Statement": [
+            {
+                "Effect": "Allow",
+                "Action": "ec2:Describe*",
+                "Resource": "*"
+            }
+        ]
+    }
+    access_key = ...
+    # create access key for an IAM user/assumed role that has the policy above.
+    # this part should call __exactly__ 4 AWS actions, so that authentication and authorization starts exactly after this
+
+    client = boto3.client('ec2', region_name='us-east-1',
+                          aws_access_key_id=access_key['AccessKeyId'],
+                          aws_secret_access_key=access_key['SecretAccessKey'])
+
+    # if the IAM principal whose access key is used, does not have the permission to describe instances, this will fail
+    instances = client.describe_instances()['Reservations'][0]['Instances']
+    assert len(instances) == 0
+```
+
+See [the related test suite](https://github.com/spulec/moto/blob/master/tests/test_core/test_auth.py) for more examples.
+
+## Experimental: AWS Config Querying
+For details about the experimental AWS Config support please see the [AWS Config readme here](CONFIG_README.md).
+
+## Very Important -- Recommended Usage
+There are some important caveats to be aware of when using moto:
+
+*Failure to follow these guidelines could result in your tests mutating your __REAL__ infrastructure!*
+
+### How do I avoid tests from mutating my real infrastructure?
+You need to ensure that the mocks are actually in place. Changes made to recent versions of `botocore`
+have altered some of the mock behavior. In short, you need to ensure that you _always_ do the following:
+
+1. Ensure that your tests have dummy environment variables set up:
+
+        export AWS_ACCESS_KEY_ID='testing'
+        export AWS_SECRET_ACCESS_KEY='testing'
+        export AWS_SECURITY_TOKEN='testing'
+        export AWS_SESSION_TOKEN='testing'
+
+1. __VERY IMPORTANT__: ensure that you have your mocks set up __BEFORE__ your `boto3` client is established.
+   This can typically happen if you import a module that has a `boto3` client instantiated outside of a function.
+   See the pesky imports section below on how to work around this.
+
+### Example on usage?
+If you are a user of [pytest](https://pytest.org/en/latest/), you can leverage [pytest fixtures](https://pytest.org/en/latest/fixture.html#fixture)
+to help set up your mocks and other AWS resources that you would need.
+
+Here is an example:
+```python
+@pytest.fixture(scope='function')
+def aws_credentials():
+    """Mocked AWS Credentials for moto."""

+
+... etc.
+```
+
+In the code sample above, all of the AWS/mocked fixtures take in a parameter of `aws_credentials`,
+which sets the proper fake environment variables. The fake environment variables are used so that `botocore` doesn't try to locate real
+credentials on your system.
+
+Next, once you need to do anything with the mocked AWS environment, do something like:
+```python
+def test_create_bucket(s3):
+    # s3 is a fixture defined above that yields a boto3 s3 client.
+    # Feel free to instantiate another boto3 S3 client -- Keep note of the region though.
+    s3.create_bucket(Bucket="somebucket")
+
+    result = s3.list_buckets()
+    assert len(result['Buckets']) == 1
+    assert result['Buckets'][0]['Name'] == 'somebucket'
+```
+
+### What about those pesky imports?
+Recall earlier, it was mentioned that mocks should be established __BEFORE__ the clients are set up. One way
+to avoid import issues is to make use of local Python imports -- i.e. import the module inside of the unit
+test you want to run vs. importing at the top of the file.
+
+Example:
+```python
+def test_something(s3):
+   from some.package.that.does.something.with.s3 import some_func # <-- Local import for unit test
+   # ^^ Importing here ensures that the mock has been established.      
+
+   some_func()  # The mock has been established from the "s3" pytest fixture, so this function that uses
+                # a package-level S3 client will properly use the mock and not reach out to AWS.
+```
+
+### Other caveats
+For Tox, Travis CI, and other build systems, you might need to also perform a `touch ~/.aws/credentials`
+command before running the tests. As long as that file is present (empty preferably) and the environment
+variables above are set, you should be good to go.

+### Caveats
+The standalone server has some caveats with some services. The following services
+require that you update your hosts file for your code to work properly:
+
+1. `s3-control`
+
+For the above services, this is required because the hostname is in the form of `AWS_ACCOUNT_ID.localhost`.
+As a result, you need to add that entry to your host file for your tests to function properly.

+This implementation is NOT complete, there are many things to improve.
+The following is a list of the most important missing features and inaccuracies.
+
+TODO add support for more principals, apart from IAM users and assumed IAM roles
+TODO add support for the Resource and Condition parts of IAM policies
+TODO add support and create tests for all services in moto (for example, API Gateway is probably not supported currently)
+TODO implement service specific error messages (currently, EC2 and S3 are supported separately, everything else defaults to the errors IAM returns)
+TODO include information about the action's resource in error messages (once the Resource element in IAM policies is supported)
+TODO check all other actions that are performed by the action called by the user (for example, autoscaling:CreateAutoScalingGroup requires permission for iam:CreateServiceLinkedRole too - see https://docs.aws.amazon.com/autoscaling/ec2/userguide/control-access-using-iam.html)
+TODO add support for resource-based policies

+

+
+        For aggregated listings, pagination logic should be set such that the next page can properly span all the region backends.
+        As such, the proper way to implement is to first obtain a full list of results from all the region backends, and then filter
+        from there. It may be valuable to make this a concatenation of the region and resource name.
