Hi all,
I am working on integration test for 4 microservices written in MSF4J.
1 - A Microservice
2 - B Microservice
3 - C Microservice
4 - D Microservice
These are implemented in a way to deploy them separately.
Application code (where we deploy the microservice using microservice
runner) will look similar to this.
public class Application {
public static void main(String[] args) {
Application application = new Application();
application.runMS(8081);
}
public void runMS(int port) {
MicroservicesRunner msRunner = new MicroservicesRunner(port);
msRunner.deploy(new AService())
.addExceptionMapper(
new AKeyExceptionMapper(),
new AExceptionMapper(),
new NotFoundExceptionMapper())
.start();
}
}
For the integration test, I want to start these four microservices with the
exception mappers. To achieve this, I tried to start this microservice in
separate threads as bellow. (in TestNG Suite)
//Run A microservice
new Thread(() -> new pathtoA.Application().runMS(8081)).start();
//Run B microservice
new Thread(() -> new pathtoB.Application().runMs(8082)).start();
//Run C microservice
new Thread(() -> new pathtoC.Application().runMs(8083)).start();
//Run D microservice
new Thread(() -> new pathtoD.Application().runMs(8084)).start();
*But I'm having a problem wherein all the four ports, only DService is
getting deployed. AFAIU this is because having multiple *
org.wso2.msf4j.MicroserviceRunner* classes in the same JVM and only one
getting loaded. *
*I have a requirement where I need to run all 4 microservice in one JVM
because of resource issues. ** Is there a way to achieve this without going
to separate JVM for each service?*
Please note those Exception mappers belong to each of the microservice
packages. And should also be tested with integration test. So that I cannot
run these service like this.
MicroservicesRunner msRunner = new MicroservicesRunner(port1,port2, port3);
microservicesRunner.deploy(serviceA, serviceB,
serivice3).addExceptionMapper(Amapper, Bmapper, cMapper).start();
Thanks and regards.
