TinyUtil is a tiny set of tiny utility functions for testing Meteor packages with Meteor's
Tinytest. It is intended for use with peterellisjones:describe.
Emulates the use of beforeEach and afterEach methods of a test class to set up and tear down a
property of an object. Useful for mocking values that only persist for the duration of the test.
describe "MyClassUnderTest", ->
# Wrapper that creates a temporary instance of `MyClassUnderTest` and attaches it to each wrapped
# test function under the `obj` property.
wrapped = swap @, 'obj', -> new MyClassUnderTest
it "can do the foo", wrapped (test) ->
test.isTrue @obj.foo()
