distributed_test's Introduction

DistributedTest

Run your Elixir tests in a distributed environment!

Usage

Use the default number of nodes (1 master + 4 slaves)

mix test.distributed

Use a specific number of nodes (1 master + n slaves). Note the master is not included in the count.

mix test.distributed --count 7

Installation

If available in Hex, the package can be installed by adding distributed_test to your list of dependencies in mix.exs:

def deps do
  [{:distributed_test, "~> 0.1.0"}]
end

Documentation can be generated with ExDoc and published on HexDocs. Once published, the docs can be found at https://hexdocs.pm/distributed_test.
