The application provides a broadcast multi-board parallel test method, system, medium and product, relates to the electronic manufacturing board test technical field, and the method comprises the following steps: a broadcast test instruction makes a plurality of to-be-tested boards start executing target test items at the same time. An initial token frame address list to be collected establishes an ordered mechanism for board access, and a first data segment provides a unified data collection space. In a token frame transmission operation, the first to-be-tested board executes differentiated token frame processing operations according to its own test state: in an unfinished state, the token frame is directly forwarded; in a completed state, test completion result data is written into the first data segment and the address list to be collected is updated. This makes the boards that have completed the test automatically exit the loop, and the boards that have not completed the test continue to participate in token transmission until the address list to be collected is empty, and the test results of all the boards are collected into the first token frame. In this way, the technical problem of low time utilization efficiency in the multi-board parallel test process in the prior art is solved.

The invention discloses a gateway host adaptive closed-loop test method and system based on intelligent plan driving, and aims to solve the problems of rigid test process, low efficiency and weak traceability of the existing gateway machine. The core of the technical scheme is to construct a complete closed loop of'plan editing-automatic matching-batch asynchronous testing-intelligent retesting-data tracing '; a multi-level tree structure including equipment types, hardware models and the like is adopted to manage a test plan, a time consumption threshold can be customized to distinguish common / asynchronous cases, and parallel execution is realized; configuration of retest times is supported, and only failed use cases are accurately retested; a structured report associated with the unique detection order number is generated, and full-process tracing is achieved. The system comprises a test plan management core module and the like, and an optional authority management module distinguishes administrator authority from common user authority. The test flexibility and universality are improved, the test time is remarkably shortened, the operation threshold is reduced, and a reliable automatic test scheme is provided for links such as gateway machine production quality inspection and factory acceptance.
