[jira] [Commented] (CAMEL-15486) Mocking of Camel Endpoints breaks because adding 3rd party dependency with spring boot

["Michel Erard (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-15486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17191657#comment-17191657 ] 

Michel Erard commented on CAMEL-15486:
--------------------------------------

So, found out what the problem is.

The Wiremock dependency has the class {{WireMockTestExecutionListener}} that does load the application context in the {{TestExecutionListener#beforeTestClass}} method that is executed earlier than the method {{CamelSpringBootExecutionListener#prepareTestInstance()}}. Means when this code is executed the camel context is already started: 
{code:java}
// we are customizing the Camel context with
// CamelAnnotationsHandler so we do not want to start it
// automatically, which would happen when SpringCamelContext
// is added to Spring ApplicationContext, so we set the flag
// not to start it just yet
SpringCamelContext.setNoStart(true);
System.setProperty("skipStartingCamelContext", "true");
{code}
 

I see two solutions: 
 # Imlement {{beforeTestClass }}as well and move this code there
 # Check if the context is already started and stop it in that case.

> {code}
> {code:java}
> java.lang.AssertionError: mock://file:output Received message count. Expected: <1> but was: <0>
