Description

Processing method and device based on test flow in test description document Technical Field The application relates to the technical field of automatic test systems, in particular to a processing method and device based on a test flow in a test description document. Background The automatic test is a key link for ensuring the quality and the reliability of products in the modern industry, in particular in the fields of aerospace, national defense electronics, automobile electronics and the like. To address the increasingly complex configuration and management challenges of test systems, the IEEE organization has established the ATML (automatic test markup language) family of standards (e.g., IEEE 1671). ATML adopts standardized schema based on XML for machine-readable description of test description, test configuration, instrument resources and tested object interfaces, and has the core design objective of realizing interoperability, portability and reusability of test assets between different test platforms and tool chains. . In an ATML-based test engineering development environment, test engineers often need to multiplex existing test flow fragments (such as a specific signal stimulus sequence, a functional test set, or a complete diagnostic routine) by copying and pasting in order to improve development efficiency. The prior art copy and paste multiplexing process mainly includes clipboard operations based on plain text or simple XML nodes, limited context copying in Integrated Development Environments (IDEs). The conflict resolution strategy mainly comprises the steps of forcedly overlaying the existing definition by replacing the new copy, automatically renaming to generate a new unique ID (such as adding a random suffix) for the newly pasted element. The prior art has the defects that the process dependence integrity is lost in the copying and pasting multiplexing process, the complete dependence graph of the test flow fragment cannot be constructed, so that a broken chain is caused, when the copied test fragment needs to be used across documents or across test stations, the system support is lost, the systematic support for dependence analysis, conflict intelligent solution and compatibility verification required by cross-environment transplantation is lacking, and the portability is extremely poor. Semantic arbitration is lost in the conflict resolution process, standard library elements (which should be globally unified) and user-defined elements (which can be controllably isolated) cannot be distinguished, and the conflict processing destroys semantics. Disclosure of Invention The application provides a processing method and a processing device based on a test flow in a test description document, which are used for solving the problems of broken chain of test logic caused by incomplete extraction of a dependency relationship, simple and rough conflict arbitration mechanism, test semantic consistency damage, lack of systematic support for cross-document and cross-test station transplantation and extremely low automation degree in the prior art.

In one possible embodiment, the multi-level dependent collection algorithm includes a direct dependent collection mode and an indirect dependent collection mode; The obtaining the direct dependency element and the indirect dependency element of the target test flow node includes: traversing the attribute and the subelement
