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 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"
Environment variables and system properties
The following environment variables must be set to enable access to the internal R3 Artifactory repository hosting Enterprise distributions: https://ci-artifactory.corda.r3cev.com/artifactory/r3-corda-releases
CORDA_ARTIFACTORY_USERNAME
CORDA_ARTIFACTORY_PASSWORD
The following system properties may be passed to the Cucumber and ScenarioRunner run-time processes:
STAGING_ROOTto specify the filesystem location of the Corda distributions to be used (as setup by the prepare.sh script)
e.g. -DSTAGING_ROOT=$HOME/staging
USE_NETWORK_SERVICESspecifies to use the Doorman/NMS service to perform setup of an Enterprise network. By default both OS and Enterprise scenarios will use the Network Bootstrapper utility to create a Corda network.
e.g. -DUSE_NETWORK_SERVICES
DISABLE_CLEANUPto prevent clean-up of runtime directories after successfully running tests.
e.g. -DDISABLE_CLEANUP
