bond build status David

the simple stub/spy javascript library

bond only provides stubbing and spy functionality. For test running and assertions, you will need to use other libraries.

This project is a safe and inclusive place for contributors of all kinds. See the Code of Conduct for details.

bond api

bond(object, 'propertyOrMethodName') returns the bond api

bond() returns an anonymous spy

bond().return(value) returns an anonymous spy that returns the given value when called

bond#to(value) replaces the value with a new value; reverts the stub after the current test completes

bond#return(value) replaces the value with a spy that returns the given value; reverts the spy after the current test completes

bond#asyncReturn(values...) replaces the value with a spy that calls the last argument passed to the function with the provided values

bond#through() replaces the value with a spy, but allows it to return its normal value

bond#restore() replaces a spy/stub with its original value; useful for implementing your own cleanup handler (see below)

bond spies

spy.called is a call count for the spy

spy.calledWith(arg1, arg2, ...) is a test for being called with specific values

spy.calledArgs is an array of methods calls, each index holds the array of arguments for that call

usage

npm install bondjs -> bond = require 'bondjs'

with mocha, qunit, jasmine: These frameworks should work with bond as is. Bond looks for a global function named either afterEach or testDone to implement its spy/stub restore functionality. If those exist, as they should when using these frameworks, it should work fine.

with some other test runner: You may need to implement your own cleanup method for bond to work properly. This might look like the following.

bond.cleanup = someTestRunner.registerAfterCallback

tests

see the test.coffee file for examples

use npm test to run the tests
