+A series of test cases that show techniques to test Spring Integration applications.
+
+
+Examples
+========
+
+...spelchain.SpelChainTests.java
+
+This test case shows how to test a fragment of a larger integration flow.
+In this example, we have a simple chain containing a header enricher and
+a transformer. It uses Direct channels. The test case shows how to 
+bridge the output channel to a queue channel so we can retrieve the
+output message after the test executes and verify the appropriate
+actions were applied to the input message.
+
+
+...splitter.CommaDelimitedSplitterTests.java
+
+This test case shows both unit testing a custom splitter class as well
+as testing it within a Spring Integration flow fragment.
+
+
+...aggregator.CommaDelimitedAggregatorTests.java
+
+This test case shows both unit testing a custom aggregator class as well
+as testing it within a Spring Integration flow fragment.
+
+
+...aggregator.ExternalGatewaySubstitutionTests.java
+
+This example is a little more complex. The application is based on a 
+travel demo presented at SpringOne in 2010. You do not need to fully understand
+the application for the purposes of this demonstration. Suffice it to 
+say that a zip code is sent to two outbound gateways (one web service, one http) and
+the weather and traffic for that zip code are aggregated together. You 
+can run the "real" application by executing the Main class in src/main/java
+and entering a valid zip code.
+
+In many cases, when integrating with external services, we can't rely on 
+those services being available while we test. Consequently, we need a 
+mechanism to stub out those services so we can run the remainder of the
+flow in a repeatable manner without need for connectivity to the services.
+This example uses dummy service activators in place of the real outbound
+gateways.
