How to set a Camel exchangeProperty from a unit test - apache-camel

Question

I have a bunch of unit tests that run camel routes with code like
// setup code here...
String route = "direct:someroute";
try (CamelContext context = new DefaultCamelContext()) {
Object response = runCamelRoute(context, route, ci);
checkResponse(route, response);
}
but this route expects an exchange property to be set before it gets here - how can I set it? CamelContext has a whole lot of methods but I can't seem to find something like:
CamelRoute cr = context.getRoute(route);
cr.getExchange().setProperty("propertyName", "propetyValue");
Here is my camel run method for unit testing, with a bit of extra code for setting up an Oracle connection, etc.
protected Object runCamelRoute(CamelContext context, String route, Object message) throws Exception {
context.addRoutes(new MyRouteBuilder() {
});
setupRegistry(context);
context.start();
FluentProducerTemplate template = context.createFluentProducerTemplate();
template.withBody(message)
.withHeader("hello", "goodbye")
.withProcessor(e -> e.setProperty("propertyName", "propertyValue")) // fail use header instead
.to(route);
try {
Future<Object> future = template.asyncRequest();
return future.get();
}
catch(Exception ex) {
System.out.println(route + " " + ex.getClass().getCanonicleName() + " " + ex.getMessage());
throw ex;
}
finally {
template.stop();
context.stop();
}
}
private void setupRegistry(CamelContext context) {
DataSource ds = DataSourceHelper.createConnectionPoolDev();
context.getRegistry().bind("dataSource", ds);
context.getRegistry().bind("Transformer", new Transformer());
}
public static OracleDataSource createConnectionPoolDev() {
try {
OracleDataSource ds = new OracleDataSource();
ds.setConnectionCacheName("oraCache");
ds.setURL("jdbc:oracle:thin:#//cluster:1521/server.domain.ca");
ds.setUser("user");
ds.setPassword("pass");
return ds;
}
catch (Exception ex) {
logger.error("Failed to create connection to the database " + ex.getMessage());
}
return null;
}

Something like this may be ?
context.createFluentProducerTemplate()
.withBody(...)
.withHeader(..., ...)
.withProcessor( e -> e.setProperty(propertyName, propertyValue) )
.to("direct:someroute")
.send();
