Test-driven database development. Write readable, easy-to-maintain unit and integration tests for your database code. DBFit is a part of FitNesse, itself an implementation of the FIT acceptance testing framework. DBFit is directly targeted at database testing. Tests are written as wiki tables with a query or procedure execute followed by a listing of the expected results.  It can handle direct SQL, stored procedures, or, with a bit of simple customization, custom procedures. 

XMLUnit is an open source project licensed under the BSD license. It provides a small library of interrelated classes that simplify each of the different ways to test XML pieces that have been outlined in the previous section. Special APIs are provided to simplify writing unit tests with J/NUnit, but the library itself is fully usable without any testing framework at all. There is a Java and a .NET version of XMLUnit. XMLUnit’s APIs will accept “pieces of XML” as input using several different forms. In most cases they can be provided as InputStreams, Readers, Strings, InputSources or readily parsed DOM Document instances. XMLUnit also provides a Transform class that can be used to apply an XSLT transformation to an existing input.

AdaControl is a free (GMGPL) tool that detects the use of various kinds of constructs in Ada programs. Its first goal is to control proper usage of style or programming rules, but it can also be used as a powerful tool to search for use (or non-use) of various forms of programming styles or design patterns. Searched elements range from very simple, like the occurrence of certaine entities, declarations, or statements, to very sophisticated, like verifying that certain programming patterns are being obeyed..

NBehave framework is based on the behavioral domain specific language (DSL) of Behavior Driven Design (BDD). The primary goal of NBehave is a framework for defining and executing application requirement goals. These characterizations are modeled after the Behavioral Driven Design (BDD) terms Story, Scenario, Given, When, Then. Relying on a syntax that is lightweight and targeted at product owners (a few "quotes" mostly), the code becomes an executable and self-describing requirements document. The definitions within the actual unit test of the application along with the nature of the architecture and the domain model makes these concepts a sound framework.

FlexUnit is a unit testing framework for Flex and ActionScript 3.0 applications and libraries. It mimics the functionality of JUnit, a Java unit testing framework, and comes with a graphical test runner. FlexUnit 4 was created to modernize testing with ActionScript 3.0 and Flex, bringing parity with the tools and techniques available to the Java community. It provides full support for unit testing in the tradition of FlexUnit .9 , but goes further with rich asynchronous support, meta-data defined testing, support for integration-level testing and an extensibility layer for new types and methods of testing.

PHPUnit is a unit testing software framework for the programming language PHP. Created by Sebastian Bergmann, PHPUnit is one of the xUnit family of frameworks that originated with SUnit. It uses assertions to verify that behavior of the unit of code under test behaves as expected. PHPUnit is the de-facto standard for unit testing in PHP projects. It provides both a framework to write the tests as well as the functionality to run the tests and analyze their results. It supports the development of object-oriented PHP applications using the concepts and methods of Agile Programming, Extreme Programming, Test-Driven Development, and Design-by-Contract Development.

Celerity is a JRuby library for easy and fast functional test automation for web applications. Celerity is a JRuby wrapper around HtmlUnit – a headless Java browser with JavaScript support. It provides a simple API for programmatic navigation through web applications.Celerity provides a superset of Watir's API.

T3 is a powerful automated unit testing tool to test Java classes. Given a target class to test, it randomly generates sequences of calls to the class' methods to test it. It catches unexpected exception; but if you had written assertions in the class, then violations to those will be caught as well. T3 is the successor of T2. The main idea is still the same as T2, however the engine has been completely revamped. Internally, T3 makes a lot of use of Java 8's closures, to make its generators infrastructure more customizable

AQtime is available as a standalone application with its own rich UI, or as a plug-in to Microsoft Visual Studio and Embarcadero RAD Studio IDEs.

Anteater is a testing framework designed around Ant, from the Apache Jakarta Project. It provides an easy way to write tests for checking the functionality of a Web application or of an XML Web service. It can test either HTTP requests or replies in various sophisticated ways. The ability to wait for incoming HTTP messages is unique to Anteater, which makes it especially useful when building tests for applications that use high level SOAP-based communication and asynchronous SOAP messages. Anteater provides XML and text logging support and the ability to render the logs into HTML reports.

HtmlUnit is a "GUI-Less browser for Java programs". It models HTML documents and provides an API that allows to invoke pages, fill out forms, click links, etc. just like in the "normal" browser. It has fairly good JavaScript support, and is able to work even with quite complex AJAX libraries, simulating either Firefox or Internet Explorer depending on the configuration you want to use. It is typically used for testing purposes or to retrieve information from web sites.     

Expect is a tool for automating interactive applications such as telnet, ftp, passwd, fsck, rlogin, tip, etc. Expect is a program to automate interactions with programs that expose a text terminal interface. Expect uses pseudo terminals (Unix) or emulates a console (Windows), starts the target program, and then communicates with it, via the terminal or console interface. Tk, another Tcl extension, can be used to provide a GUI.

AgitarOne Agitator provides a unique interactive understanding of code behavior as a developer writes or modifies Java classes or methods. Agitation helps developers validate the expected behavior of their code and discover unexpected behaviors. Agitator automatically creates dynamic test cases, synthesizes sets of input data, and analyzes the results. When objects depend on other objects, Agitator automatically constructs those objects, enabling full analysis of the possible behaviors of the code, even if it depends on third-party libraries.
