Example 1
When network oscillation usually occurs, the current common method is that the client test software reconnects the network tester and restarts automatic testing, but this method is time-consuming, especially the reliability or stability test generally requires a test time not less than 48 hours. Therefore, the problem that the network tester is interrupted in the test caused by the network oscillation is solved, and the test efficiency can be improved.
Under the condition, the network tester is still ensured to carry out normal test, the network tester updates and caches the test result to the local, and the test data is sent to the client test software after the network is recovered to be normal. This eliminates the need to spend a significant amount of time and labor again for testing. The specific method comprises the following steps:
1. the network tester device serves as a server and configures the session delay disconnection duration. When the network tester detects that the network is abnormally disconnected with the client, the network tester still continues to test within the session delay disconnection duration, and the network tester stops testing only when the specified delay duration is reached, so that local resources are released. The method ensures that the network interruption does not influence the test within a certain time, but the test can be stopped after the delay time if the network is actually interrupted.
2. The client stops the test by sending an application layer message to the network tester and disconnects the network connection. The method can ensure that the test interruption is caused by the normal request of the client.
3. And after the connection is disconnected, the client reestablishes the network connection at regular time, and after the connection is recovered, the network tester actively reports the test result to the client. This avoids loss of test data.
The method for preventing the network tester from being interrupted due to the network oscillation comprises the following steps:
step M1: the client test software establishes network connection with the network tester equipment, and after the test is started, the network tester returns a test data result to the client test software for processing in real time;
step M2: if network oscillation occurs, the network connection between the client test software and the network tester is disconnected, the server side detects that the application layer message request is not interrupted, the network tester still normally tests at the moment, the internal record of the network connection state is abnormal, and meanwhile test data are cached to the local;
step M3: after detecting the network interruption, the client continuously tries to reestablish the network connection according to the configuration retry time and the retry times. After the network connection is reestablished, the network tester sets the connection state to be normal, and the cached test data is uploaded to the client;
step M4: if the network is still not recovered after the delay time, the network tester judges the network fault, stops testing and releases local resources.
The system for preventing the network tester from being interrupted due to the network oscillation comprises the following components:
module M1: the client test software establishes network connection with the network tester equipment, and after the test is started, the network tester returns a test data result to the client test software for processing in real time;
module M2: if network oscillation occurs, the network connection between the client test software and the network tester is disconnected, the server side detects that the application layer message request is not interrupted, the network tester still normally tests at the moment, the internal record of the network connection state is abnormal, and meanwhile test data are cached to the local;
module M3: after detecting the network interruption, the client continuously tries to reestablish the network connection according to the configuration retry time and the retry times. After the network connection is reestablished, the network tester sets the connection state to be normal, and the cached test data is uploaded to the client;
module M4: if the network is still not recovered after the delay time, the network tester judges the network fault, stops testing and releases local resources.
