The invention provides a test method, which is applied to a micro-service architecture. The micro-service architecture comprises a first service and a second service, and the method comprises the following steps: monitoring a first transaction request message sent to the second service by the first service; determining whether the first transaction request message can be used for testing the second service; if it is determined that the first transaction request message can be used for testing the second service, generating a plurality of first test request messages used for requesting the service from the second service based on the first transaction request message; sending a plurality of first test request messages to a second service; and monitoring the response of the second service tothe plurality of first test request messages to realize the test of the second service. The invention further provides a device test, an electronic device and a computer readable storage medium.
