Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, embodiment of the present invention is described further in detail.
A kind of computer implemented method that the embodiment of the present invention provides test case to screen, with reference to shown in Fig. 1, the method comprises:
101, at least one test elements in the goal systems that will test is obtained;
102, the weighted value of test elements is set;
103, according to the weighted value of test elements, the weighted value comprising the combination of at least one test elements is set;
104, basis comprises the weighted value of the combination of at least one test elements, from the test case that test case memory storage stores, at least screen a test case.
A kind of computer implemented method that the embodiment of the present invention provides test case to screen, by the weighted value screening test cases of at least one test elements in goal systems, ensure that the integrality of test case, and improve the screening effeciency of test case, improve the reliability of test case screening.
A kind of computer implemented method that the embodiment of the present invention provides test case to screen, in embodiments of the present invention, can according to the test elements chosen, form State Tree, this State Tree is formed when being selected test elements generation power set element, according to leaf node in State Tree, export the combination of test elements and the weighted value of respective combination.The combination of test elements that State Tree is formed is orderly, complete, comprehensively and effective, and the test set that test deviser exports according to State Tree, the i.e. number of test elements and weighted value selection test case in test set.
With reference to shown in Fig. 2, the method comprises:
201, at least one test elements in the goal systems that will test is obtained.
Wherein, this test elements is selected in system under test (SUT), separate and can combination in any mutually.
202, the weighted value of test elements is set according to preset algorithm.
Concrete, preset algorithm comprises:
Defect reference value B* the 3rd number percent of complexity O* the second number percent+test elements of importance reference value I* the first number percent+test elements of the weighted value=test elements of test elements.
Wherein, weighted value comprises importance reference value I, complexity O and defect reference value B.
Concrete, the basis of design of weighted value: importance, the complexity of considering test elements.If the version before system had test, then it is also conceivable to the distribution situation of defect.
Each test elements sets its importance reference value
i, complexity
oand defect reference value
b(optional).Therefore the weighted value of each test elements is
t=I+O+B;
The defect of 80% appears in the middle of the code of 20%, thus in the weighted value of test elements each element rate of specific gravity be set as importance reference value
ithe first number percent be 20%, complexity
othe second number percent be 80%(zero defect reference value
bwhen making reference, the 3rd number percent is 0%), if the situation that system under test (SUT) has last version to test makes reference, then the first number percent of significance level accounts for 13%, and the second number percent of complexity accounts for 67%, defect reference value
bthe 3rd number percent account for 20%, if partial test element value does not have test defect, then also can give a small amount of weighted value.
Wherein importance reference value
isetting principle: all test elements are sorted according to significance level, ensure that the importance reference value of test elements is inconsistent.Complexity
osetting principle: sort according to the size of code that test elements relates to; Defect reference value
bsetting principle: the bug situation of testing according to front edition system, bug is more, then the defect reference value of this test elements
bhigher.
Each test elements according to after the sequence of importance reference value, complexity and defect reference value, according to centesimal system test elements weighted value established standards is: total test elements number is respectively
n, the weighted value of adjacent test elements difference after sequence
x=[100/
n], represent 100/
nafter round, the test elements weighted value that importance reference value (complexity or defect reference value) is the highest
i=100, the weighted value of an adjacent rear test elements importance reference value (complexity or defect reference value) is: 100-
x, by that analogy.
Table 1 test elements weight table
203, the weighted value of all test elements included by the combination comprising at least one test elements is added respectively, obtains the weighted value comprising the combination of at least one test elements.
Concrete, generate State Tree according to selected test elements, this State Tree illustrates the whole process that test elements is combined to form, and the leaf node generating State Tree contains all array configurations of test elements.
Each test elements in test elements combination can be a set, or empty set, or contains an element in test elements set, or two elements or multiple element in test elements set, also can equal test elements set.Otherwise from each unit of test elements set usually, it only has two states: it or belong to test elements combination, or do not belong to test elements combination.Can regard as in the hope of test elements anabolic process and each element in selected test elements " got " successively or the process of " giving up ".
Can by a State Tree: represent the process that test elements assembled state changes.State Tree has
n+1layer,
nrepresent the number of test elements in the test elements set selected.The original state (for empty set) that the test elements that represents root node in tree combines; Leaf node, represents its final state.
State Tree forming process is: the 1st layer is root node (for empty), and the 2nd layer of left sibling represents gets the 1st element, and right node represents succession father node; Accept or reject the 2nd element in 3rd layer, on the 2nd layer of basis, increase the 2nd element in left sibling on the basis of father node, right node keeps last layer father node value constant, by that analogy; Represent and to carry out and the
ithe branch node of layer, then represent to front
i-1process is got/given up to individual element, until the
n+ 1 layer, represent right
nindividual test elements is got/is given up, and the leaf node of this State Tree is exactly the end-state of test elements combination, and the process therefore asking test elements to combine is the process traveling through whole State Tree.
State Tree has following features:
The level of node defines from root node, and root is ground floor, and the child of root is the second layer.If certain node is
ilayer, then the root of its subtree is just the
i+1layer, does not have subtree.
Each node only has two stalk trees at the most, and the subtree of State Tree has dividing of left and right, and its order can not be put upside down arbitrarily, and namely this tree also can be referred to as state binary tree.
Concrete, in the State Tree generated, leaf node is all combination of test elements, and mark the test weighted value W of this leaf node, this test weighted value W is all test elements weighted value sums in leaf node.That is:
(
for the weighted value of i-th test elements in leaf node, n represents test elements numbers whole in leaf node), export according to the weighted value size descending of leaf node.
204, according to the size order of the weighted value of the combination of all test elements, from the test case that test case memory storage stores, a test case is at least screened.
Concrete, test deviser, according to certain rule, selects corresponding test case.Under normal circumstances, need the number considering test elements in testing combination, and these two factors of weighted value of test elements combination, testing combination can be selected to comprise a test elements, two test elements ... and
nthe multiple situation such as individual test elements.
