Problems solved by technology

[0003] At present, redundant samples can only be set through the personal experience of test designers, and the judgment of redundancy is mainly used in hardware equipment or software systems. In the field of software testing, there is a lack of quantitative judgment methods for the redundancy of test data samples. It is also impossible to judge the redundancy of existing test data samples

Embodiment Construction

[0022] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] In the field of software testing, redundant samples can only be set according to human experience, and the redundancy of test data samples lacks quantitative judgment indicators. When designing or selecting test data sample sets, there is a lack of scientific judgment criteria for redundancy. , cannot accurately measure the redundancy of test data samples. Therefore, the purpose of this discovery is to propose a quantitative determination method for the redundancy of data samples according to the characteristics of test data samples in the field of software testing, so as to solve the problem of quantitative determination of the redundancy of data samples in t...

Abstract

The invention provides a data sample redundancy quantitative determination method and system. The method comprises the following steps: determining a uniform value range interval of an input item, and naming the input item according to the value range interval; replacing the test data value in the sample by using the value range interval name; judging whether completely identical interval name samples exist or not; if the completely identical interval name samples do not exist, calculating the occurrence frequency of each interval name of the input item; calculating the redundancy of each test data sample according to the occurrence frequency of each interval name; and calculating the redundancy of the test data sample set according to the redundancy of each test data sample. According to the data sample redundancy quantitative determination method and system provided by the invention, the redundancy of the test data sample set can be quantitatively determined.

Description

technical field [0001] The invention relates to the technical field of software testing, in particular to a method and system for quantitatively judging the redundancy of data samples. Background technique [0002] In the process of software testing, in order to improve the test quality, the test data samples need to cover the combination of each input item as comprehensively as possible. efficiency. Therefore, in order to balance the relationship between test quality and test efficiency, some redundant samples are artificially set up according to the specific conditions such as the importance of the tested part and the test progress requirements, so that the software test can run as fast as possible on the premise of meeting the progress requirements. It is possible to comprehensively cover the combination of various input items. [0003] At present, redundant samples can only be set through the personal experience of test designers, and the judgment of redundancy is main...
