In this blog we will show how a WEB API created using Tapestry can be tested. Testing a web service is not straight forward as the PageTester, the default way of testing in Tapestry, doesn't allow for testing API. To overcome this difficulty we must start a Jetty server with custom/test web.xml. The test web.xml allows us to control the construction of objects. In this example we show how a mock service object can be inserted for testing, while using the full implementation for production.
This blog is part of a series of blogs on Tapestry that explains how to build a "simple" hello world example html page and expose the functionality of the page(s) via a WEB API. In a previous blog we showed how to setup a web API that responses in either XML or JSON. If you haven't read it yet, it's probably a good idea to have a look at this blog first before proceeding.
This blog picks things up from another previous blog in the series on testing page. The basic of testing a webpage generated with Tapestry are explained there. In this blog we will build on the code previously created.
