Embodiment Construction

[0032] In order to make the purpose, content, and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] The idea of ​​the traversal search method generated by pairwise combination test cases of the present invention is briefly described as: to traverse all possible test cases one by one, not only to make the current test case cover as many uncovered combinations as possible, but also to take into account when looking for the next test case , to have the opportunity to cover as many uncovered combinations as possible. It can be briefly summarized as follows: not only the current multi-coverage, but also the subsequent multi-coverage should be considered. The trade-off between the two can be realized by weighting factors, the weight a of the current multi-coverage, and the weight b of the subsequent multi-coverage. ...

Abstract

The invention discloses a traversal search method generated by pair combination testing, which comprises: determining a combination of values of all parameters; forming a combination of all two values to form a set of combinations of two parameters; setting the combination of all paired parameters to a set of values that are not covered; setting a set of test cases; selecting a set of values T belonging to all sets of parameter values but not belonging to the set of test cases; counting the combination T covers the number of combinations G in all combinations of values that are not covered; S8, counting the combination T has the largest number of occurrences of H in all combinations not included in all unsetable combinations of values; S9, calculating F = a * G-b * H; finding out the maximum combination of all F values belonging to all parameter value combination sets but not belonging to test case sets. The combination of the values covered by the element Tmax is eliminated in all combinations of values that are not overwritten.

Description

technical field [0001] The invention provides a novel and efficient traversal search method for the problem of pairwise combination test case generation. Background technique [0002] When testing software, it is necessary to test various states of the system. When generating pairwise test cases, it is necessary to select multiple test cases to complete the test. [0003] For example, the system has multiple parameters, and each parameter has multiple values: [0004] Suppose the system has 3 parameters: [0005] The first parameter has 2 values ​​= {Windows XP, Windows 2000}; [0006] The second parameter has 3 values ​​= {English, Chinese, Japanese}; [0007] The third parameter has 2 values ​​= {Word 2003, Word 2007}; [0008] Each parameter in the test takes a value to form a test case, for example: [0009] A test case: (Windows 2000, Japanese, Word 2007). [0010] For example, in the following 5 test cases: [0011] Test case 1: (Windows 2000, Japanese, Word 200...
