Rapise is a next generation software test automation tool that leverages the power of open architecture to improve application quality and reduce time to market. Using advanced technology and an extensible architecture, Rapise can handle your software application and cross-browser testing needs

TimeShiftX is a date and time simulation software that allows testers to "time travel" their servers and software applications in the future or past to test all date and time sensitive functionality and code such as end of year/month/quarter, daylight savings, leap year, billing, insurance rates, policies, expiration dates, pensions, financial validation, mortgages, etc. TimeShiftX enables you to “time travel” without doing any manual work such as code modifications, changing server clocks, or isolating servers, thus simplifying & speeding up your testing while saving you cost, time, and resources.

Cantata++ is designed as a software testing tool for use mainly with C, C++, but with some useful functionality for Java. It combines the ability to generate test scripts with test coverage analysis. It can be run on all main host platforms (Windows, Linux, Solaris and others), with the same as target platforms plus many embedded platforms. Using Eclipse as the basis for its IDE Cantata++ is able to lead the user through the generation of a template test script, leaving to the user the need only to add chosen input values and expected outputs. The tool also provides the ability to simulate external calls, by means of stub and wrapper functionality. Coverage analysis includes support for Entry Point, Statement, Decision (branch) and Decision coverage.

Inspired by JUnit, csUnit brings the power of unit testing to the .NET framework. csUnit is your key to unit testing and test-driven development using .NET languages such as C#, Visual Basic .NET, Visual J#, or Managed C++.

Effort is a powerful tool that enables a convenient way to create automated tests for Entity Framework based applications. It is basically an ADO.NET provider that executes all the data operations on a lightweight in-process main memory database instead of a traditional external database. It provides some intuitive helper methods too that make really easy to use this provider with existing ObjectContext or DbContext classes. A simple addition to existing code might be enough to create data driven tests that can run without the presence of the external database.

JOSIT (Java Observation Simulation Inspection Toolkit) is an open Application Programmer's Interface for instrumenting applications written in the Java programming language. JOSIT seamlessly integrates with any Java application written using Sun Microsystem's standard library of Java graphical objects. JOSIT observes user actions, inspects the state of objects and scripts graphical events. Tools written in other programming languages may communicate with JOSIT via sockets.

Embedded Unit is unit testing framework for Embedded C System. It's design was copied from JUnit and CUnit and more, and then adapted somewhat for Embedded C System. Embedded Unit does not require std C libs. All objects are allocated to const area.

Embedded Unit is delivered as two part static library. First part delivers the basic unit test framework. The second part adds functionality with additional test result outputters, like XML outputter.

PolySpace Verifier enables embedded software developers to detect run-time errors in C, C++ and Ada before they compile and run the code and prove automatically which operations are error-free.
Overflows, out of bounds array index and divide-by-zero errors, amongst others, are easily detected by PolySpace which models the flow of data through the code.
PolySpace Verifier can also be integrated into Model-Based Design tools such as Simulink from The MathWorks to trace back errors to their root cause in the model.
PolySpace’s Verifier is used extensively for Embedded Software development and more especially in the Transportation, Defense, Aerospace and Automotive industries where there is a high expectation of safety-critical systems.

Concordion is an open source framework for Java that lets you turn a plain English description of a requirement into an automated test — an active specification.

MutaTesting is a mutation testing tool for PHP. Mutation testing (or Mutation analysis or Program mutation) evaluates the quality of software tests. Mutation testing involves modifying a program's source code or byte code in small ways. MutaTesting supports PHPUnit and atoum. You can create an adapter for any PHP testing framework.
