Issue Description
I use sentinel to implement resiliency for by web services.
I found it is very difficult to write multiple tests for the same resource with different rules because sentinel keeps context from the previous test.
For example sentinel_block_requests_total is already not null when the second test is running.
How to reset/clean all sentinel counts before each test using public API?
I use the following code:
ClusterNode node = ClusterBuilderSlot.getClusterNode(nodeName);
if (node!=null) {
node.reset();
node.metrics().clear();
node.metrics().values().clear();
}
But it does not help
I still see that node.totalExceptiopnI() is not set to 0
Describe what happened (or what feature you want)
I need to reset all counters to null

Hi, if you're resetting the metrics of resources, you may just use
ClusterBuilderSlot.getClusterNodeMap().clear()to clear the ClusterNode map.7rfyedvj2#
Thanks for the response. It breaks all next tests since no resources exist anymore. For example if I call such method,ClusterBuilderSlot.getClusterNodeMap().clear(), then when I run my tests the code fails on NPE because the line below returns null: ClusterNode node = ClusterBuilderSlot.getClusterNode(nodeName); So I need to reload all rules for all resources and to allow to get cluster node by resource name I run ClusterBuilderSlot.resetClusterNodes(); but it does not help - still getting NPE because ClusterBuilderSlot.getClusterNode(nodeName) is null. Do you know how to resolve it?…

Hi Eric,
please update if you have a fix to reset all counters to 0 when ClusterBuilderSlot.getClusterNodeMap().clear() is called
