# boto3-fixtures
[](https://pypi.org/project/boto3-fixtures/) [](https://travis-ci.com/github/alphachai/boto3-fixtures) [](https://codecov.io/gh/alphachai/boto3-fixtures)
**boto3-fixtures** provides test fixtures for your local AWS cloud stack.
Testing software which touches cloud infrastructure doesn't have to be difficult! `boto3-fixtures` provides a dead-simple framework for setup+teardown of mocked AWS infrastructure. Use in combination with projects like moto or localstack.
### Supports
* Kinesis
* SQS
* SNS
* S3
* Lambda
* DynamoDB
*Please submit a PR or issue if you'd like to see support for a specific AWS service!*
## Getting Started
This library provides a context decorator, `boto3_fixtures.Service`, which will setup and teardown AWS services.
```python
import boto3_fixtures
with boto3_fixtures.Service("sqs", queues=["my-queue"]) as svc:
# Queues exist
for queue in svc.state["queues"]:
print(f"{queue.name} - {queue.arn} - {queue.url}")
# Queues destroyed
```
Combine this with a local testing stack of your choice (moto, localstack).
```python
import boto3_fixtures, moto
with moto.mock_sqs():
with boto3_fixtures.Service("sqs", queues=["first-queue", "second-queue"]) as svc:
# ...
```
### Generating Pytest Fixtures
To make your life even easier, we've boiled all of the above down into pytest fixture generators.
```python
import boto3_fixtures as b3f
aws = b3f.contrib.pytest.moto_fixture(
services=["dynamodb", "kinesis", "sqs", "s3", "lambda"],
scope="class",
)
sqs = b3f.contrib.pytest.service_fixture("sqs", scope="class", queues=fixtures.SQS)
kinesis = b3f.contrib.pytest.service_fixture("kinesis", scope="class", streams=fixtures.KINESIS)
dynamodb = b3f.contrib.pytest.service_fixture("dynamodb", scope="class", tables=fixtures.DYNAMODB)
s3 = b3f.contrib.pytest.service_fixture("s3", scope="class", buckets=fixtures.S3)
lam = b3f.contrib.pytest.service_fixture("lambda", scope="class", lambdas=fixtures.LAMBDA)
sns = b3f.contrib.pytest.service_fixture("sns", scope="class", topics=fixtures.TOPICS)
# Example Usage
def test_my_code(sqs):
boto3.client("sqs").list_queues()
```
#### The `aws()` fixture
To ensure your mocked cloud is a dependency of your service fixtures, boto3-fixtures expects you to create a fixture named `aws`. If you don't take advantage of this, your local cloud stack may be torn down before your service, leading to boto3 exceptions when tearing down the services.
```python
# Example: localstack via pytest-localstack
import pytest_localstack
aws = pytest_localstack.patch_fixture(
services=["sqs"],
scope="class",
)
# Example: moto via boto3-fixtures
import boto3_fixtures as b3f
aws = b3f.contrib.pytest.moto_fixture(
services=["sqs"],
scope="class",
)
```
### Configuring Services
Configuration of a service may be either a list of *names* `List[str]` or a list of *configs* `List[dict]` containing boto3 parameters.
| Service | List of Names | List of Configs |
| -------- | ------------- | --------------- |
| s3 | yes | yes |
| sqs | yes | yes |
| kinesis | yes | yes |
| dynamodb | | yes |
| lambda | | yes |
| sns | yes | yes |
For example, your configuration might look like this:
```python
S3 = ["first-bucket", "second-bucket"]
SQS = ["first-queue", "second-queue"]
KINESIS = ["first-stream", "second-stream"]
DYNAMODB = [
{
"AttributeDefinitions": [
{"AttributeName": "uri", "AttributeType": "S"},
{"AttributeName": "timestamp", "AttributeType": "S"},
],
"TableName": "test-dbd-table",
"KeySchema": [
{"AttributeName": "uri", "KeyType": "HASH"},
{"AttributeName": "timestamp", "KeyType": "RANGE"},
],
}
]
LAMBDA = [
{
"zip_path": "dist/build.zip",
"FunctionName": "my_lambda",
"Runtime": "python3.6",
"Environment": {"foo": True},
}
]
SNS = [
"my-topic-with-default-attrs",
{
"Name": "my-topic-with-additional-params",
"Tags": [{"Key": "key1", "Value": "val1"}],
"Attributes": {
"DisplayName": "YourSystemIsOnFireTopic",
},
}
]
```
These configurations don't have to be static. You could use a pytest fixture to build or compile a list of resources that you want mocked.
### Using both `moto` and `localstack`
You can point the `aws` fixture at moto or localstack to explicitly to require a specific stack to exist for the duration of your service fixture. For example, if you use both stacks:
```python
# conftest.py
stack_config = {
"services": ["dynamodb", "kinesis", "sqs", "s3", "lambda"],
"scope": "class",
"autouse": False,
"region_name": "us-east-1",
}
localstack = pytest_localstack.patch_fixture(**stack_config)
moto = b3f.contrib.pytest.moto_fixture(**stack_config)
@pytest.fixture(scope="class")
def aws(moto):
pass
# component/conftest.py
@pytest.fixture(scope="class")
def aws(localstack):
pass
```
## Known Issues
* Using both pytest-localstack and moto in the same project may break if the pytest-localstack tests run first. It's suspected this is due to an issue with cleanup with the pytest-localstack session, but is this is still under investigation.
