ExUnitEx provides extra assertions for testing process side effects when invoking functions that start or stop several processes. These assertions are assert_processes_started, assert_processes_stopped, and assert_processes_survived macros for use in ExUnit tests.
The assertion macros will take in two arguments - the function that starts or stops the processes and a list of expected process side effects. The expected process side effects will be in the form of a keyword list, where each key represents a process and the value is a list of expected side effects for that process. When assertion succeeds, it returns the result of passed function.
defmodule ExUnitEx.AssertionsTest do
use ExUnit.Case, async: true
import ExUnitEx.Assertions
test "assert_processes_started success" do
assert :processes_started ==
assert_processes_started(
fn -> :processes_started end,
registry: %{
test_registry_one: :agent_foo,
test_registry_two: [:agent_bar, :agent_baz]
},
names: [:foo, :bar, :baz]
)
end
