             Summary: SpringSamplingThrottlerTest.testSamplingWithPropertyPlaceholder always fails - missing route in Spring XML config
                 Key: CAMEL-23306
                 URL: https://issues.apache.org/jira/browse/CAMEL-23306
             Project: Camel
          Issue Type: Bug
          Components: camel-spring-xml
            Reporter: Guillaume Nodet


The test {{SpringSamplingThrottlerTest.testSamplingWithPropertyPlaceholder}} always fails with a 30-second timeout.

h3. Root cause

The parent test {{SamplingThrottlerTest}} (in {{core/camel-core}}) defines a route:
{code:java}
from("direct:sample-placeholder").sample("{{sample.period}}").to("mock:result");
{code}

The Spring test {{SpringSamplingThrottlerTest}} (in {{components/camel-spring-parent/camel-spring-xml}}) extends the parent and inherits the {{testSamplingWithPropertyPlaceholder()}} method. However, the Spring XML config file {{samplingThrottler.xml}} only defines 3 routes:
* {{direct:sample}}
* {{direct:sample-messageFrequency}}
* {{direct:sample-messageFrequency-via-dsl}}

The {{direct:sample-placeholder}} route is *missing* from the XML config. When the inherited test method sends a message to {{direct:sample-placeholder}}, the message has nowhere to go and the mock endpoint never receives it, causing a 30-second timeout.

h3. Fix

Add the missing route to {{samplingThrottler.xml}}:
{code:xml}
<route>
    <from uri="direct:sample-placeholder"/>
    <sample samplePeriod="{{sample.period}}"/>
    <to uri="mock:result"/>
</route>
{code}

Alternatively, override {{testSamplingWithPropertyPlaceholder()}} in the Spring test to skip it if the route is intentionally excluded.

h3. Affected files
* {{components/camel-spring-parent/camel-spring-xml/src/test/resources/org/apache/camel/spring/processor/samplingThrottler.xml}}
* {{components/camel-spring-parent/camel-spring-xml/src/test/java/org/apache/camel/spring/processor/SpringSamplingThrottlerTest.java}}
