Order, so that first node service switchover state.
In the present embodiment, first node executes the switching of service condition, example after the order for receiving service switchover state
It such as is switched to leader node from follower's node, or is switched to follower's node from leader node, specific switching side
Formula is determined by the order of service switchover state, switches form so as to be accurately controlled the service condition of first node, into
And working condition of the first node when service condition switches can be tested.
Two, time delay.
The specific implementation of time delay are as follows: injector manager is default first after intercepting and capturing the first request message
The rear order that service switchover state is sent to first node of period, so that first node delayed switching service condition.
In the present embodiment, time delay belongs to a kind of operation irregularity state, therefore, prolongs to test first node in the time
Working condition under late, through injector manager after intercepting and capturing the first request message, deliberately service switchover state is replied in delay
Order time, the time span of delay: the specific duration of the first preset time period can be by tester according to actually making
It is adjusted with demand, so as to accurately detect under different delay state, whether the working condition of first node is normal.
Three, abnormality code is sent.
Sending the specific implementation of abnormality code are as follows: injector manager sends abnormality code to first node, so that
Obtain the working result of the first node output error.
In the present embodiment, injector manager is sent out after the request message for receiving first node transmission to first node
Abnormal code is sent, so that the first node becomes an error node (or Byzantium's node), and then is tested, when first
When node is error node, can entire block catenary system fault-tolerant to the error node, to ensure the work of entire block catenary system
Work is not influenced by the error node.
Four, it sends and restores code.
Sending the step of restoring code can carry out after above-mentioned transmission abnormality code step, specific implementation are as follows:
Injector manager is sent to first node restores code, restores code and is used for suppressing exception code, so that first node is defeated
Correct working result out.
In the present embodiment, in real work, after state supervisor has sent abnormality code to first node, condition managing
Device itself may perceive this exception, and reissue recovery code to first node, so that first node restores to transport again
Make, therefore, during test block chain node, need to detect this mechanism whether can normal operation therefore sending
After complete abnormality code, injector manager is sent to first node restores code, and then tests after receiving recovery code, the
Can one node be restored to normal working condition in abnormal operation, input correct working result.
It should be noted that above-mentioned first scene operation is a kind of citing, in practical work process, tester can be with
According to test needs, any abnormal operation is edited, later by injector manager by abnormal operation injection the
In one node, to realize the detection to first node, further, this method can also be used to detect simultaneously multiple nodes, right
