I want to create an integration test with CamelBlueprintTestSupport. I start my Camelcontext which looks ok at first:
[ main] ingRestJobAdvertApiOfFirstbird INFO Skipping starting CamelContext as system property skipStartingCamelContext is set to be true. [ main] BlueprintCamelContext INFO Apache Camel 2.15.1.redhat-620133 (CamelContext: camel-1) is starting
Routes are also starting. But then I just get this message within my console:
In main loop, we have serious trouble: java.lang.NullPointerException java.lang.NullPointerException at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:303)
Camel Version: 2.15.1.redhat-620133
The Unit Test:
public class WhenUsingRestJobAdvertApiOfdemo extends CamelBlueprintTestSupport {
@Override
protected String getBlueprintDescriptor() {
return "OSGI-INF/blueprint/blueprint.xml";
}
@Override
protected String[] loadConfigAdminConfigurationFile() {
return new String[]{"src/test/resources/jobwebsite.connector.properties", "jobwebsite.connector"};
}
@Test
public void testRoute() throws Exception {
context.addRoutes(new MockServiceEndpoints());
JobRequest jobRequest = readJoData();
template.sendBody("direct:createjobIndemo", jobRequest);
String expectedBody = "<matched/>";
template.sendBodyAndHeader(expectedBody, "foo", "bar");
}
public JobRequest readJoData() throws IOException {
ObjectMapper mapper = new ObjectMapper();
JobRequest jobRequest = mapper.readValue(new File("src/test/resources/demo-data/job-Advert/job-123.json"), JobRequest.class);
return jobRequest;
}
}
There is a known issue in camel: https://issues.apache.org/jira/browse/CAMEL-7985
Solution, which works for me posted here: https://issues.jboss.org/browse/ENTESB-2225. Let's copy useful comment here:
When stepping up projects to 6.2 GA - my camel-test-blueprint unit tests all throw this NullPointerException excessively. I looked at the resolution of the bug report and applied that to my poms, and it cleared up all the NPEs. Here is what I did:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-test-blueprint</artifactId>
<scope>test</scope>
<!-- Exclude in order to prevent -->
<!-- java.lang.NullPointerException at org.apache.felix.fileinstall.internal.DirectoryWatcher.run(DirectoryWatcher.java:303) -->
<exclusions>
<exclusion>
<groupId>org.apache.felix</groupId>
<artifactId>org.apache.felix.fileinstall</artifactId>
</exclusion>
</exclusions>
</dependency>
Additionally, I had to add the following dependency:
<dependency>
<groupId>org.apache.felix</groupId>
<artifactId>org.apache.felix.utils</artifactId>
<scope>test</scope>
</dependency>
