    Roboelectric

    Roboelectric

    Android unit testing framework

    Robolectric is the industry-standard unit testing framework for Android. With Robolectric, your tests run in a simulated Android environment inside a JVM, without the overhead of an emulator. Running tests on an Android emulator or device is slow! Building, deploying, and launching the app often takes a minute or more. That’s no way to do TDD, there must be a better way. Robolectric is a framework that brings fast and reliable unit tests to Android. Tests run inside the JVM on your workstation in seconds. Robolectric is built using Gradle. Both IntelliJ and Android Studio can import the top-level build.gradle file and will automatically generate their project files from it. Robolectric supports running tests against multiple Android API levels. The work it must do to support each API level is slightly different, so its shadows are built separately for each. If you would like to live on the bleeding edge, you can try running against a snapshot build.

    Roth

    Roth

    Roth is a full-stack enterprise application development framework.

    Roth is a full-stack framework for enterprise web application development in Java. Though it can be characterized as an M.V.C. framework, a more accurate description would be a M.U.S.I.C. framework (Model Utility Servlet Interface Client). The Model and Utility components provide a simple persistence-like interface to database back-ends, without the complexity or overhead of JPA or Hibernate. The servlet component provides a simple and easy way to generate concise controller code with automatic POST processing. The Interface and Client components provide simple and easy components which reduce the code necessary to create UI pages. All components are designed to work in concert to provide a consistent code set, however you have the freedom to use portions with other frameworks as desired. Roth is a continuation and successor of the JpPortal framework. (Roth is an Irish word pronounced 'row-h' which means 'wheel' -- as in "Why reinvent the wheel?" -- "To make it better!")
