Screening method and device of test data

Abstract

The invention provides a screening method and device of test data. The method comprises the steps of: inputting a to-be-tested program and a test data set, wherein the test data set comprises a plurality of test data; analyzing the to-be-tested program to obtain a plurality of paths of the to-be-tested program; respectively loading the plurality of test data to the to-be-tested program so as to obtain the corresponding path of each test datum; and screening the plurality of test data in the test data set according to the corresponding path of each test datum. According to the method provided by the embodiment of the invention, business software is not required to provide interfaces and the corresponding paths of the test data in the test data set can be obtained, so that the user access cost is low and the use is convenient; and a screening module is capable of screening the test data set according to the corresponding path of each test datum and extracting the most simplified test data set which covers all the paths of the to-be-tested program from the numerous test data, so that the test speed is greatly accelerated and the test period is shortened.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for screening test data. Background technique [0002] In order to improve the test speed and shorten the test cycle, the test data of the test case is generally screened. Currently, the test data is screened mainly based on the branch coverage. It is necessary to insert the ccover provided by ccover into the test program code under the premise of installing the ccover compiler program. Coverage event statistics interface, after each test data is tested, as long as the coverage rate increases, it means that the test program enters a new branch, that is, the test data is considered valid and stored as the final test data, otherwise it is considered invalid. [0003] However, this data screening method needs to install the ccover compiler program, which is expensive to use, and needs to insert and call the coverage event statistics interface in the test progra...

AI Technical Summary

Problems solved by technology

[0003] However, this data screening method needs to install the ccover compiler program, which is expensive to use, and needs to insert and call the coverage event statistics interface in the test program, and the user needs to modify some files, which is cumbersome to use
