AWSsert

AWSsert is a Python library providing declarative assertions about AWS resources to your tests.

Installation

Use the package manager pip to install AWSsert.

pip install awssert

Usage

Installing the package will make AWSserts extra assertions available to all of your tests. Assertions are attached directly to boto3 resource objects, allowing you to write clean and declarative tests:

import boto3

def test_bucket_contains_object():
   bucket = boto3.resource("s3").Bucket("foo")
   assert bucket.should_not.contain("bar")
   bucket.put_object(Key="bar", Body=b"123")
   assert bucket.should.contain("bar")

AWSsert also works in tandem with moto, enabling the same level of clarity to be applied on mock infrastructure:

import boto3
from moto import mock_s3

@mock_s3
def test_mock_bucket_contains_object():
   bucket = boto3.resource("s3").Bucket("foo")
   assert bucket.should_not.contain("bar")
   bucket.put_object(Key="bar", Body=b"123")
   assert bucket.should.contain("bar")
