cipra is a simple, TAP-compatible Unit Testing Framework for C++. It's written in 100% standard C++11 and is only a couple of header files, making it easy to include in your C++11 project. TAP, the Test Anything Protocol, is a standard output format for software unit test frameworks which was originally designed for Perl, but can serve other languages. It has a rich number of tools ("harnesses") which parse TAP-formatted output and do useful things with it. TAP, however, is equally human-readable. The name cipra (pronounced /ˈʃi.pɾaː/ "SHEE-prah") comes from the lojban phrase "lo cipra", which means "the test". It is properly written with an initial minuscule "c", even when at the start of a sentence.
Citrus is a test framework written in Java that enables automated integration testing of message-based enterprise SOA applications. The tool can easily simulate surrounding systems across various transports and protocols (e.g. JMS, SOAP WebServices, HTTP, TCP/IP, etc.) in order to perform end-to-end use case testing. Citrus provides strong validation mechanisms for XML message contents and allows you to build complex testing logic such as sending and receiving messages, database validation, automatic retries, variable definitions, dynamic message contents, error simulation, and many more.
Simple Fuzzer is a very simple fuzzer. It is reminiscent of easy-fuzz from 2004, written by priest of the priestmasters. His layout for building a fuzzy test was a "script" file with a preamble, setting some basic state and variables followed by the "meat and potatoes" tests. This approach was borrowed for Simple Fuzzer.
6jack is a framework for testing, analyzing, and fuzzing network applications. 6jack runs a command, intercepts calls to common network-related system calls, and passes them through an external filter. A filter can be written in any language supporting the MessagePack serialization library. 6jack is especially useful for writing tests for clients and servers, debugging and reverse engineering protocols, sketching filtering proxies, and fuzzing.
MASH is a modular, automated script harness. It allows users to implement simple harnesses that perform work external to a system. The framework will invoke that harness as outlined by an XML script. For example, when using the framework to test a system you could create a script that cleans and loads a database, FTPs some data, submits a login form, and verifies HTTP information. Harnesses can easily be built to do almost anything (many harnesses are provided), not just Web page verification. While harnesses are written in Java, the scripts may be run against any type of system as harnesses are intended to act as clients.
The Java Engine for Testing (JET) is a system for running distributed automated tests. It has been used by Sun for testing the High Availability DataBase (HADB), JavaDB, PostgreSQL, Memcached, and the MySQL Cluster Manager. JET should be a good way to write your tests if the product you want to test is distributed or has a client/server architecture, if it is natural for you to write the tests in Java, and if you want to invest time in developing tests and abstractions for later reuse.
