The invention relates to the field of testing, and discloses a business
test case library establishment method and device, equipment and a storage medium, which are used for improving the accuracy of detecting a
business function by using a business
test case library. The method for establishing the business
test case library comprises the following steps of matching a preset logical operation formula for each business test case by utilizing a test detection
algorithm to obtain a
business case mapping library; obtaining a target
business function required in the target business task and a corresponding target business test case; executing the target business test case based on the
business case mapping library, generating a target execution logic, calculating an analysis coverage rate based on the target execution logic, and supplementing the
business case mapping library according to the analysis coverage rate; and carrying out clustering operation on the plurality of service test cases by utilizing a clustering analysis
algorithm, and carrying out regression operation on the plurality of service test cases subjected to the clustering operation to obtain a final service test case library. The invention further relates to a block chain technology, and the business test case can be stored in the block chain.
