Example 1 with NodeSelectorSlot

use of com.alibaba.csp.sentinel.slots.nodeselector.NodeSelectorSlot in project Sentinel by alibaba.

the class DefaultSlotChainBuilderTest method testBuild.

@Test
public void testBuild() {
    DefaultSlotChainBuilder builder = new DefaultSlotChainBuilder();
    ProcessorSlotChain slotChain = builder.build();
    assertNotNull(slotChain);
    // Verify the order of slot
    AbstractLinkedProcessorSlot<?> next = slotChain.getNext();
    assertTrue(next instanceof NodeSelectorSlot);
    // Store the first NodeSelectorSlot instance
    NodeSelectorSlot nodeSelectorSlot = (NodeSelectorSlot) next;
    next = next.getNext();
    assertTrue(next instanceof ClusterBuilderSlot);
    next = next.getNext();
    assertTrue(next instanceof LogSlot);
    next = next.getNext();
    assertTrue(next instanceof StatisticSlot);
    next = next.getNext();
    assertTrue(next instanceof AuthoritySlot);
    next = next.getNext();
    assertTrue(next instanceof SystemSlot);
    next = next.getNext();
    assertTrue(next instanceof FlowSlot);
    next = next.getNext();
    assertTrue(next instanceof DegradeSlot);
    next = next.getNext();
    assertNull(next);
    // Build again to verify different instances
    ProcessorSlotChain slotChain2 = builder.build();
    assertNotNull(slotChain2);
    // Verify the two ProcessorSlotChain instances are different
    assertNotSame(slotChain, slotChain2);
    next = slotChain2.getNext();
    assertTrue(next instanceof NodeSelectorSlot);
    // Store the second NodeSelectorSlot instance
    NodeSelectorSlot nodeSelectorSlot2 = (NodeSelectorSlot) next;
    // Verify the two NodeSelectorSlot instances are different
    assertNotSame(nodeSelectorSlot, nodeSelectorSlot2);
}
