Phaeton Framework

What is Phaeton Framework

Phaeton Framework is an application framework responsible for establishing and maintaining the interactions between the modules of a Phaeton blockchain application.

Phaeton Framework aims to provide a consistent and intuitive interface between each module and component. Currently, Phaeton Framework establishes interactions between the chain, api and network modules.

Architecture Overview

The architecture of Phaeton Framework follows the research documented in LIP0005. The diagram below provides a high-level overview of the architecture:

Installation and usage

To install and use Phaeton Framework follow the steps described in the Phaeton SDK installation and usage sections.

Tests

Preparing Node

• Recreate the database to run the tests against a new blockchain:

dropdb phaeton_dev
createdb phaeton_dev

• Launch Phaeton (runs on port 4000):

NODE_ENV=test npm start

Running Tests

Starting from version 1.6.0, Phaeton Framework will be using Jest as its main test runner with gradual deprecation of mocha. Since rewriting all existing mocha tests is not feasible at the moment, we have two test runners in our code base:

• Modules (all source code under framework/src/modules folder) will be tested using mocha and test files should be located under framework/test/mocha.
• Framework (all of the source files but framework/src/modules) will be tested using jest and test files should be located under framework/test/jest.
• Functional and Network tests suites will be using mocha and test files should be located under framework/test/mocha.

Running Mocha Tests

Tests are run using the following command:

npm run mocha:<testType> -- [testPathPattern] [mochaCliOptions]

• Where testType can be one of unit, integration, functional:ws, functional:get, functional:post, functional:put, functional, network (required).
• Where testPathPattern is a regexp pattern string that is matched against all tests paths before executing the test (optional).
• Where mochaCliOptions can be any of mocha's command line options (optional).

Examples:

# Running network tests
npm run mocha:network
npm run mocha:network -- --grep @p2p
npm run mocha:network -- --grep @propagation

# Running unit tests
npm run mocha:unit
npm run mocha:unit -- --grep @slow
npm run mocha:unit -- --grep @unstable
### extensive
npm run mocha:unit -- --grep="@unstable" --invert

# Running integration tests
npm run mocha:integration -- --grep @slow
npm run mocha:integration -- --grep @unstable
# extensive
npm run mocha:integration -- --grep="@unstable" --invert

# Running functional tests
npm run mocha:functional:ws
npm run mocha:functional:get
npm run mocha:functional:post
npm run mocha:functional:put

Individual test files can be run using the following commands:

npm run mocha:unit -- <testPathPattern> [mochaCliOptions]

or

npm run mocha <filepath> [mochaCliOptions]

or

npx mocha <filepath> [mochaCliOptions]

Running Jest Tests

npm run jest:<testType>

testType can be unit|integration|functional

Executing the tests per file:

npm run jest:<testType> -- [testPathPattern] [jestCliOptions]

Contribution

To test the changes in framework you can run,

node test/test_app or node test/test_app | npx bunyan

If you want to test the changes in phaeton-sdk/elements to reflect in phaeton-sdk/framework, please make sure you run npm run build at phaeton-sdk after making any changes in elements library and run node test/test_app.
