Integration testing can be very hard, especially when there is no sufficient tool support. Unit testing is flavored with fantastic tools and APIs like JUnit, TestNG, EasyMock, Mockito and so on. These tools support you in writing automated tests. A tester who is in charge of integration testing may lack of tool support for automated testing especially when it comes to simulate messaging interfaces.
In a typical enterprise application scenario the test team has to deal with different messaging interfaces and various transport protocols. Without sufficient tool support the automated integration testing of message-based interactions between interface partners is exhausting and sometimes barely possible.
The tester is forced to simulate several interface partners in an end-to-end integration test. The first thing that comes to our mind is manual testing. No doubt manual testing is fast. In long term perspective manual testing is time consuming and causes severe problems regarding maintainability as they are error prone and not repeatable.
The Citrus framework gives a complete test automation tool for integration testing of enterprise applications. You can test your message interfaces to other applications as client and server. Every time a code change applies all automated Citrus tests ensure the stability of interfaces and message communication.
Regression testing and continuous integration is very easy as Citrus fits into your build lifecylce as usual Java unit test. You can use Citrus with JUnit or TestNG in order to integrate with your application build.
With powerful validation capabilities for various message formats like XML, CSV or JSON Citrus is designed to provide fully automated integration tests for end-to-end use cases. Citrus effectively composes complex messaging use cases with response generation, error simulation, database interaction and more.
