Tools for running Quorum clusters and integration tests

Quorum Tools

This project contains tools for running Quorum clusters and integration testing Quorum.

Installation

Install Quorum 2.0 and Constellation so they're on your PATH.

Install Haskell Stack.

Now, in the project directory:

$ stack setup # this is only necessary to run once
$ stack build

At this point, you can run any of the built binaries using stack exec:

$ stack exec -- local-new

Or you can use stack install to install them on your machine (make sure ~/.local/bin is on your $PATH):

$ stack install
$ local-new

To run all integration tests in batch, make sure that you can sudo (for packet filtering), and then run:

$ stack test

The following invocation might help to enable packet filtering during the test suite, if sudo requires a password on your machine:

$ sudo whoami && stack test

To run tests interactively, you can run them from the REPL:

$ stack ghci quorum-tools:lib

Tests

Here are some high-level cluster tests that we include in our suite:

• Continually adding and removing nodes from a cluster until none of the initial members are left
• Partitioning a node from the rest of the network
• Public and private state consistency
• Stopping, then restarting a node
• Revoking a node's membership in the cluster, re-registering it, and bringing it back online

The test sources are located in src/QuorumTools/Test/.

Running a cluster

We also include scripts for running a cluster without necessarily testing it.

• local-new: create and start a new cluster, destroying old data directories (under gdata in the current directory)
• local-start: start a cluster from existing data directories (under gdata in the current directory)
• local-spam: send a rate-limited stream of transactions to a geth node

local-new runs indefinitely, with multiple geths forked from the process. While the cluster is up and running, you can inspect the logs from the geth nodes (e.g. tail -f geth1.log), or send in transactions -- e.g. local-spam -g 1 -r 10 will send 10 transactions per second to geth 1 while it is running. Additionally you can attach to a geth node via its IPC file under gdata: geth attach gdata/geth1.geth.ipc. If the local-new process is stopped, you can restart the cluster from the existing datadirs under gdata by issuing local-start.
