Code testing method, node and system

The embodiment of the invention provides a code test method, node and system, which can be used in the technical field of test security, and comprises the following steps: each node in a distributed system obtains test data correspondingly required by all test cases configured by the node; each node configures the test data to a corresponding test case in a test environment to generate a test result file; each node compares the test result file with a preset standard file, and if the test result file is consistent with the preset standard file, a comparison result record is uploaded to a public server; and the public server knows the test cases which do not pass the test according to the comparison result records uploaded by the nodes. The method and the device meet the requirement of centralized processing of batch services, automatic testing of the batch services is realized, and the service risk is reduced; manual assertion writing is not needed, and the workload of testers is reduced; and favorable condit
