mountebank - Over the wire test doubles

•    HTML

In fact, halfway through we discovered our corporate mocking software couldn’t handle the sheer amount of performance testing we were running as part of this effort (we completely crushed some pretty industrial enterprise software in the process). As a result, we made the call to move the entire program over to a Mountebank OSS-based solution with a custom provision to give us the ability to expand/shrink our mocking needs on demand. mountebank is the first open source tool to provide cross-platform, multi-protocol test doubles over the wire. Just point your application to mountebank instead of the real dependency, and test like you would with traditional stubs and mocks.

mockery - Simplifying the use of mocks with Node.js

•    Javascript

If you've tried working with mocks in Node.js, you've no doubt discovered that it's not so easy to get your mocks hooked up in the face of Node's module loading system. When your source-under-test pulls in its dependencies through require, you want your mocks provided, instead of the original module, to enable true unit testing of your code. This is exactly the problem Mockery is designed to solve. Mockery gives you a simple and easy to use API with which you can hook in your mocks without having to get your hands dirty with the require cache or other Node implementation details.

testdouble.js - A minimal test double library for TDD with JavaScript

•    Javascript

Welcome! Are you writing JavaScript tests and in the market for a mocking library to fake out real things for you? testdouble.js is an opinionated, carefully-designed test double library maintained by, oddly enough, a software agency that's also named Test Double. If you practice test-driven development, testdouble.js was designed to promote terse, clear, and easy-to-understand tests. There's an awful lot to cover, so please take some time and enjoy our documentation, which is designed to show you how to make the most out of test doubles in your tests.

mockery - Mockery is a simple yet flexible PHP mock object framework for use in unit testing with PHPUnit, PHPSpec or any other testing framework

•    PHP

Mockery is a simple yet flexible PHP mock object framework for use in unit testing with PHPUnit, PHPSpec or any other testing framework. Its core goal is to offer a test double framework with a succinct API capable of clearly defining all possible object operations and interactions using a human readable Domain Specific Language (DSL). Designed as a drop in alternative to PHPUnit's phpunit-mock-objects library, Mockery is easy to integrate with PHPUnit and can operate alongside phpunit-mock-objects without the World ending. Mockery is released under a New BSD License.

Cuckoo - Boilerplate-free mocking framework for Swift!

•    Swift

Cuckoo was created due to lack of a proper Swift mocking framework. We built the DSL to be very similar to Mockito, so anyone using it in Java/Android can immediately pick it up and use it. Cuckoo has two parts. One is the runtime and the other one is an OS X command-line tool simply called CuckooGenerator.

dyson - Node server for dynamic, fake JSON.

•    Javascript

Node server for dynamic, fake JSON. When developing client-side applications, often either static JSON files, or an actual server, backend, datastore, or API, is used. Sometimes static files are too static, and sometimes an actual server is not available, not accessible, or too tedious to set up.

Kakapo.js - :bird: Next generation mocking framework in Javascript

•    Javascript

Kakapo its a full featured http mocking library, he allows you to entirely replicate your backend logic in simple and declaritive way directly in the browser. This way you can easily prototype and develop the whole Application without backend and just deactivate Kakapo when you go production. In order to achieve that Kakapo gives you a set of utilities like Routing, Database, Response, Request and so on... Use the kakapo router to declare two custom routes and returning custom data.

node-mocks-http - Mock 'http' objects for testing Express routing functions

•    Javascript

Mock 'http' objects for testing Express routing functions, but could be used for testing any Node.js web server applications that have code that requires mockups of the request and response objects. This project is available as a NPM package.

project-stub - Simple BEM project example

•    Javascript

Project-stub is a template project repository used for BEM projects creation. It contains the minimal configuration files and folders you will need for quick start from scratch. Note: If your operating system is Windows, you must run the following commands in Git Bash with administrator rights. Make sure that you launch Git Bash as an administrator.

api-mock - Creates a mock server based on an API Blueprint

•    HTML

This project is no longer under active development and we're looking for a new maintainer (or owner). Please open an issue if you are interested in helping out. API-Mock is a node.js npm module that generates a mock server (express) from your API specification. Document your API in the API blueprint format, and API-Mock mocks your routes and sends the responses defined in the api spec.

DynamoDBStub

A low-level stub for DynamoDB, designed for test environment, with a default EntityFramework implementation for data access.

Legend Fakes - Fake it easy!

A dynamic fake framework. * Easier semantics, all fake objects are just that - fakes - the use of the fakes determines whether they're mocks or stubs. * Context aware fluent interface guides the developer. * Full VB.Net support.

mock-require - Simple, intuitive mocking of Node.js modules.

•    Javascript

mock-require is useful if you want to mock require statements in Node.js. I wrote it because I wanted something with a straight-forward API that would let me mock anything, from a single exported function to a standard library. The module you that you want to mock. This is the same string you would pass in if you wanted to require the module.

apimocker - node.js module to run a simple http server for mock service responses.

•    Javascript

Then you can visit "http://localhost:7878/first" in your browser to see it work. The quiet and port options can also be set in the config.json file, and values from config.json will override values from the command line. After you get up and running, you should put your config.json and mock responses in a better location. It's not a good idea to keep them under the "node_modules" directory. Make sure another process is not already using the port you want. If you want port 80, you may need to use "sudo" on Mac OSX. Sometimes you only want some service endpoints to be mocked, but have other requests forwarded to real service endpoints. In this case, provide the proxy URL option on startup e.g. apimocker --proxy http://myrealservice.io When the proxy option is set, any requests to apimocker with URLs that are not configured with mock files, will be forwarded to the specified URL.

Amber - Reflective PE packer.
