moonpie.test_helpers¶
Test helpers and extra assertions are provided for the Busted <http://olivinelabs.com/busted/> testing framework.
Array Extensions¶
A number of array helpers are available:
it("has some array elements", function()
local test = { 1, 2, 3, 4 }
assert.array_includes(1, test)
end)
Mock Store¶
Mocks the redux style store that manages state. Allowing easier testing of components that are dependent on the store.
describe("My test harness", function()
local mock_store = require "moonpie.test_helpers.mock_store"
local initial_state = { values = true }
local store = mock_store(initial_state)
it("can track dispatches", function()
system_under_test.do_thing_that_dispatches()
assert.equals(1, #store.get_actions("action_type"))
end)
end)
General helpers¶
- spy_to_func
- Converts a spy routine into a pure function. This can be helpful in situations where the code under test responds differently to tables vs functions.
