Continuous Integration is a software development practice where members of a team integrate their work frequently, usually each person integrates at least daily - leading to multiple integrations per day. Each integration is verified by an automated build (including test) to detect integration errors as quickly as possible. Many teams find that this approach leads to significantly reduced integration problems and allows a team to develop cohesive software more rapidly. This article is a quick overview of Continuous Integration summarizing the technique and its current usage.
Myna is a revolutionary new form of A/B testing that learns as you test. It uses multi armed bandit algorithms to optimize your tests in real time, giving you faster results and greater ROI.

ScalaCheck is a powerful tool for automatic unit testing of Scala and Java programs. It features automatic test case generation and minimization of failing test cases. ScalaCheck started out as a Scala port of the Haskell library QuickCheck, and has since evolved and been extended with features not found in Haskell QuickCheck.
There is a perception about usability testing that it is both time consuming and expensive. While it can be time consuming, good usability testing certainly can
ServiceFixture is a fixture library built on top of FIT/FitNesse which enables FitNesse to be the integration test and software collaboration platform for service oriented and distributed systems. These systems usually expose stateless services, such as web service (SOAP or REST), ejb and POJO etc, to its internal or external clients, and complex domain objects are always involved in the service interfaces.
It is difficult to leverage FitNesse for these systems due to the fact that it is not trivial to represent complex domain objects in FIT test table, and hence it would require constant fixture development efforts to support the integration test. ServiceFixture is designed to fill this gap.
ServiceFixture uses expression language to represent domain objects, verify and display the response in FIT test table. Every ServiceFixture test is basically a method invocation to a stateless service. The test starts with setting up the input data, then invoking the service operation, and then checking the response.
Because the ServiceFixture is very generic, to setup ServiceFixture and FitNesse for a project, you only need to write a ServiceFixture extension to encapsulate the invocation logic once, which is pretty trivial. No more fixture development is needed after that. It also provides template creator integrated with FitNesse to make tester's life a lot easier too.
ServiceFixture also provides database service fixtures(SelectFixture and UpdateFixture) which can be used to access databases directly from FitNesse test scripts. See Tutorial for more details.
