Examples with PredicateArgsEvent org.springframework.cloud.gateway.event.PredicateArgsEvent used on opensource projects

Example 1 with PredicateArgsEvent

use of org.springframework.cloud.gateway.event.PredicateArgsEvent in project spring-cloud-gateway by spring-cloud.

the class WeightCalculatorWebFilterTests method receivesPredicateArgsEvent.

@Test
public void receivesPredicateArgsEvent() {
    WeightCalculatorWebFilter filter = mock(WeightCalculatorWebFilter.class);
    doNothing().when(filter).addWeightConfig(any(WeightConfig.class));
    doCallRealMethod().when(filter).handle(any(PredicateArgsEvent.class));
    HashMap<String, Object> args = new HashMap<>();
    args.put("weight.group", "group1");
    args.put("weight.weight", "1");
    PredicateArgsEvent event = new PredicateArgsEvent(this, "routeA", args);
    filter.handle(event);
    ArgumentCaptor<WeightConfig> configCaptor = ArgumentCaptor.forClass(WeightConfig.class);
    verify(filter).addWeightConfig(configCaptor.capture());
    WeightConfig weightConfig = configCaptor.getValue();
    assertThat(weightConfig.getGroup()).isEqualTo("group1");
    assertThat(weightConfig.getRouteId()).isEqualTo("routeA");
    assertThat(weightConfig.getWeight()).isEqualTo(1);
}

Example 2 with PredicateArgsEvent
