MarkTLite / interfaces-storages

An Image storage app that applies interfaces and dependency injection for better code quality. Providers include AWS_S3, local disk storage

Interfaces (Storages)

Description

This project involves the application of design patterns to develop an image storage app with the following advantages:

• High extensibility (Storage Providers' function definitions like for dropbox can be added without complicating the codebase at all)
• Dependency change does not fail the system

Concepts applied

• Storage providers: Aws_S3, local disk storage
• Interfaces
• Dependency Injection
• Test driven development

Adding Providers

add commandline argument for the new provider in the tests file Make sure the test_databases.py tests even when unchanged pass for your newly added providers' logic

Running Tests

pip install coverage
Run tests for each provider in this format:
coverage run tests\test_storages.py aws_s3
where "aws_s3" is one of:

• aws_s3
• filesystem

Getting coverage

use -a to append individual tests
coverage run tests\test_storages.py aws_s3 && coverage run -a tests\test_storages.py filesystem
then
coverage report

Environment files

Add these files in the /providers folder before running.

.env for aws_s3

aws_access_key_id = ***
