ex_unit_clustered_case v0.3.1 ExUnit.ClusteredCase.Node
This module handles starting new nodes
You can specify various options when starting a node:
:name
, takes either a string or an atom, in either long or short form, this sets the node name and id.:boot_timeout
, specifies the amount of time to wait for a node to perform it’s initial boot sequence before timing out:init_timeout
, specifies the amount of time to wait for the node agent to complete initializing the node (loading and starting required applications, applying configuration, loading test modules, and executing post-start functions):erl_flags
, a list of arguments to pass toerl
when starting the node, e.g.["-init_debug"]
:env
, a list of tuples containing environment variables to export in the node’s environment, e.g.[{"PORT", "8080"}]
:config
, aKeyword
list containing configuration overrides to apply to the node, should be in the form of[app: [key: value]]
:post_start_functions
, a list of functions, either captured or in{module, function, args}
format, which will be invoked on the node after it is booted and initialized. Functions must be zero-arity.
