Examples with OriginsInventory com.hotels.styx.client.OriginsInventory used on opensource projects

Example 1 with OriginsInventory

use of com.hotels.styx.client.OriginsInventory in project styx by ExpediaGroup.

the class StyxBackendServiceClientFactoryTest method createsClients.

@Test
public void createsClients() {
    StyxBackendServiceClientFactory factory = new StyxBackendServiceClientFactory(environment);
    OriginsInventory originsInventory = newOriginsInventoryBuilder(backendService.id()).metrics(environment.centralisedMetrics()).connectionPoolFactory(simplePoolFactory()).initialOrigins(backendService.origins()).build();
    OriginStatsFactory originStatsFactory = mock(OriginStatsFactory.class);
    BackendServiceClient client = factory.createClient(backendService, originsInventory, originStatsFactory);
    assertThat(client, is(instanceOf(StyxBackendServiceClient.class)));
// note: for more meaningful tests, perhaps we need to add package-private accessor methods to StyxBackendServiceClient
// there is also the issue that the Transport class assumes it will get a NettyConnection, so mocks can't be used
// these problems are both outside the scope of the current issue being implemented
// so for the time being, this test is mostly a placeholder
}
