The embodiment of the invention relates to a parameter passing test method and device, equipment and a storage medium, and the method comprises the steps: obtaining out-parameter data corresponding to the in-parameter data from
test flow data as test out-parameter data in response to the in-parameter data matched with a target field condition from the
test flow data of a target
test object, and enabling the out-parameter data to serve as the test out-parameter data; the method comprises the following steps: acquiring in-parameter data meeting a target field condition from reference flow data of a target
test object, acquiring out-parameter data corresponding to the in-parameter data from the reference flow data as reference out-parameter data, and comparing the test out-parameter data with the reference out-parameter data to obtain comparison result information. According to the embodiment of the invention, the test-out parameter data and the reference-out parameter data of the input parameter data meeting the target field condition are obtained from the
test flow data and the reference flow data, and the difference data between the test-out parameter data and the reference-out parameter data is determined through parameter comparison so as to reflect the parameter transfer test result, so that the probability that the application program has a parameter
transfer error is reduced.
