Building the fabric

The following instructions assume that you have already set up your development environment.

To build the Fabric:

cd $GOPATH/src/
make dist-clean all

Running the unit tests

Use the following sequence to run all unit tests

cd $GOPATH/src/
make unit-test

To run a subset of tests, set the TEST_PKGS environment variable. Specify a list of packages (separated by space), for example:

export TEST_PKGS=""
make unit-test

To run a specific test use the -run RE flag where RE is a regular expression that matches the test case name. To run tests with verbose output use the -v flag. For example, to run the TestGetFoo test case, change to the directory containing the foo_test.go and call/excecute

go test -v -run=TestGetFoo

Running Node.js Unit Tests

You must also run the Node.js unit tests to insure that the Node.js client SDK is not broken by your changes. To run the Node.js unit tests, follow the instructions here.

Running Behave BDD Tests

Note: currently, the behave tests must be run from within in the Vagrant environment. See the development environment setup instructions if you have not already set up your Vagrant environment.

Behave tests will setup networks of peers with different security and consensus configurations and verify that transactions run properly. To run these tests

cd $GOPATH/src/
make behave

Some of the Behave tests run inside Docker containers. If a test fails and you want to have the logs from the Docker containers, run the tests with this option:

cd $GOPATH/src/
behave -D logs=Y

Building outside of Vagrant

It is possible to build the project and run peers outside of Vagrant. Generally speaking, one has to ‘translate’ the vagrant setup file to the platform of your choice.

Building on Z

To make building on Z easier and faster, this script is provided (which is similar to the setup file provided for vagrant). This script has been tested only on RHEL 7.2 and has some assumptions one might want to re-visit (firewall settings, development as root user, etc.). It is however sufficient for development in a personally-assigned VM instance.

To get started, from a freshly installed OS:

sudo su
yum install git
mkdir -p $HOME/git/src/
cd $HOME/git/src/
git clone
source fabric/devenv/

From this point, you can proceed as described above for the Vagrant development environment.

cd $GOPATH/src/
make peer unit-test behave

Building on Power Platform

Development and build on Power (ppc64le) systems is done outside of vagrant as outlined here. For ease of setting up the dev environment on Ubuntu, invoke this script as root. This script has been validated on Ubuntu 16.04 and assumes certain things (like, development system has OS repositories in place, firewall setting etc) and in general can be improvised further.

To get started on Power server installed with Ubuntu, first ensure you have properly setup your Host’s GOPATH environment variable. Then, execute the following commands to build the fabric code:

mkdir -p $GOPATH/src/
cd $GOPATH/src/
git clone
sudo ./fabric/devenv/
cd $GOPATH/src/
make dist-clean all


Configuration utilizes the viper and cobra libraries.

There is a core.yaml file that contains the configuration for the peer process. Many of the configuration settings can be overridden on the command line by setting ENV variables that match the configuration setting, but by prefixing with ‘CORE_’. For example, logging level manipulation through the environment is shown below:



Logging utilizes the go-logging library.

The available log levels in order of increasing verbosity are: CRITICAL | ERROR | WARNING | NOTICE | INFO | DEBUG

See the logging-control document for instructions on tweaking the level of log messages to output when running the various Fabric components.
