corda/experimental/behave

Introduction

This project illustrates how one can use Cucumber / BDD to drive and test homogeneous and heterogeneous Corda networks on a local machine. The framework has built-in support for Dockerised node dependencies so that you easily can spin up a Corda node locally that, for instance, uses a 3rd party database provider such as MS SQL Server or Postgres.

Structure

The project is split into three pieces:

• Testing Library (main) - This library contains auxiliary functions that help in configuring and bootstrapping Corda networks on a local machine. The purpose of the library is to aid in black-box testing and automation.

• Unit Tests (test) - These are various tests for the library described above. Note that there's only limited coverage for now.

• BDD Framework (scenario) - This module shows how to use BDD-style frameworks to control the testing of Corda networks; more specifically, using Cucumber.

Setup

To get started, please follow the instructions below:

• Go up to the root directory and build the capsule JAR.

  $ cd ../../
  $ ./gradlew install
  

• Come back to this folder and run:

  $ cd experimental/behave
  $ ./prepare.sh
  

This script will download necessary database drivers and set up the dependencies directory with copies of the Corda fat-JAR and the network bootstrapping tool.

Selective Runs

If you only want to run tests of a specific tag, you can append the following parameter to the Gradle command:

$ ../../gradlew scenario -Ptags="@cash"
# or
$ ../../gradlew scenario -Ptags="@cash,@logging"
