A command-line interface for preparing and outputting Cumulus Messages for Cumulus Tasks
# Cumulus Message Adapter
cumulus-message-adapter is a command-line interface for preparing and outputting Cumulus Messages for Cumulus Tasks. cumulus-message-adapter helps Cumulus developers integrate a task into a Cumulus Workflow.
Read more about how the cumulus-message-adapter works in the [CONTRACT.md](./CONTRACT.md).
[CircleCI](https://circleci.com/gh/cumulus-nasa/cumulus-message-adapter) manages releases and release assets.
Whenever CircleCI passes on the master branch of cumulus-message-adapter and message_adapter/version.py has been updated with a version that doesn’t match an existing tag, CircleCI will:
- Create a new tag with tag_name of the string in message_adapter/version.py
- Create a new release using the new tag, with a name equal to tag_name (equal to version).
- Build a cumulus-message-adapter.zip file and attach it as a release asset to the newly created release. The zip file is created using the [Makefile](./Makefile) in the root of this repository.
These steps are fully detailed in the [.circleci/config.yml](./.circleci/config.yml) file.
### Dependency Installation
$ pip install -r requirements-dev.txt $ pip install -r requirements.txt
### Running Tests
Running tests requires [localstack](https://github.com/localstack/localstack).
Tests only require localstack running S3, which can be initiated with the following command:
` $ SERVICES=s3 localstack start `
And then you can check tests pass with the following nosetests command:
` $ CUMULUS_ENV=testing nosetests -v -s `
$ pylint message_adapter
If changes are made to the codebase, you can create the cumulus-message-adapter zip archive for testing libraries that require it:
`bash $ make clean $ make cumulus-message-adapter.zip `
Then you can run some integration tests:
`bash ./examples/example-node-message-adapter-lib.js `
