JTemplate is an open-source implementation of the CTemplate templating system (aka "Mustache") for Java. It also provides a set of classes for implementing template-driven REST services in Java. Templates are documents that describe an output format such as HTML, XML, or CSV. They allow the ultimate representation of a data structure to be specified independently of the data itself, promoting a clear separation of responsibility.

YatSpec is an open source library that replaces test tools like Concordion and Fit by allowing your tests to stay maintainable (i.e refactoring support in you favourite IDE) while still producing human readable documentation.

* TableRowTest support for JUnit Methods (like in MBUnit / NUnit)
* Specification support for Junit. Produces readable Html from your test
* "Given / When / Then" support with automatic capturing and display of "givens" and captured inputs and output.

CUTE is an easy to use C++ unit testing framework that leverages modern C++ libraries and features. CUTE is orthogonal, easily extendable and much simpler than other C++ unit testing approaches like CPPUnit. For example, CUTE does not require that you write a derived class for each C++ class you want to unit test.

DbSetup is an open-source Java API that helps you setup your database data to execute DAO/Repository unit tests. It plays in the same league as tools like DBUnit, but is much simpler, and focuses on a single task: populate the database with test data.

Mockator is an open source Eclipse CDT plug-in for C++ Seams and Mock Objects. Mockator offers a header-only mock object library and an Eclipse plug-in to create test doubles in a simple yet powerful way. It leverages new C++11 language facilities while still being compatible with C++03.

Claudia.js makes it easy to deploy Node.js projects to AWS Lambda and API Gateway. It automates all the error-prone deployment and configuration tasks, and sets everything up the way JavaScript developers expect out of the box. This means that you can get started with Lambda microservices easily, and focus on solving important business problems instead of dealing with AWS deployment workflows.

HTTP-RPC is an open-source framework for simplifying development of REST applications. It allows developers to access REST-based web services using a convenient, RPC-like metaphor while preserving fundamental REST principles such as statelessness and uniform resource access. The project currently includes support for consuming services in Java, Objective-C/Swift, or JavaScript.

MarkupKit is an open-source framework for simplifying development of native iOS applications. It allows developers to construct user interfaces declaratively using a human-readable markup language, rather than visually using Interface Builder or programmatically in code.

Webmock.io provides custom http endpoints for testing. It acts like a real webservice, but provided the content it was configured to deliver. The website allows for easy creation of such custom mocks that can then be used under a unique url.
