Examples with CanaryService io.scalecube.services.routings.sut.CanaryService used on opensource projects

Example 1 with CanaryService

use of io.scalecube.services.routings.sut.CanaryService in project scalecube by scalecube.

the class RoutersTest method test_remote_service_tags.

@Test
public void test_remote_service_tags() throws Exception {
    CanaryService service = gateway.call().router(Routers.getRouter(WeightedRandomRouter.class)).api(CanaryService.class);
    Thread.sleep(1000);
    AtomicInteger serviceBCount = new AtomicInteger(0);
    int n = (int) 1e3;
    Flux.range(0, n).flatMap(i -> service.greeting(new GreetingRequest("joe"))).filter(response -> response.getResult().contains("SERVICE_B_TALKING")).doOnNext(response -> serviceBCount.incrementAndGet()).blockLast(Duration.ofSeconds(3));
    System.out.println("Service B was called: " + serviceBCount.get() + " times out of " + n);
    assertTrue((serviceBCount.doubleValue() / n) > 0.5, "Service B's Weight=0.9; more than half of invocations have to be routed to Service B");
}
