[embodiment]
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Embodiment one,
The method flow diagram of the determination regression test scope that Fig. 1 provides for the embodiment of the present invention one, as shown in Figure 1, the method can comprise the following steps:
Step 101: determine the functional unit in software to be tested.
The functional unit related in this step can be the visible functional unit of user, and the visible functional unit of so-called user refers to operating or the minimum black box function point of observable software of can seeing from software interface.
The determination of the visible functional unit of these users can based on the user's request document of software to be tested or feature list, one of them user's request can the visible functional unit of corresponding multiple user, and a function in feature list also can the visible functional unit of corresponding multiple user.Usual software development team has user's request document or the feature list of functional unit definition granularity for software, the list of a requirement developing sequencing can be enumerated out in user's request document or feature list, namely the priority of the visible functional unit of each user realizes sequential list, just can determine the visible functional unit of all users of software to be tested by traveling through this user's request document or feature list.Certainly, the usual quantity of the visible functional unit of the user in usual software is not too large, also by the mode of artificial combing, can determine the visible functional unit of each user according to artificial input.
Certainly, except the visible functional unit of above-mentioned user, also can be the functional unit of other smaller particle size or more coarsegrain, realizing in the present invention be similar, at this only for the visible functional unit of user, repeats no longer one by one.
Step 102: according to the dependence between the functional unit determined, constructing function dependent tree.
After determining functional unit, need to determine the dependence between each functional unit, this dependence embodies the dependence of priority on function technology realizes.Restrained by the description in step 101, the list of a requirement developing sequencing can be enumerated out in user's request document or feature list, when traverse user requirement documents or feature list, the functional unit that each functional unit relies on can be determined, thus automatically generating a function dependence table, each list item of this function dependence table comprises: the dependence of functional unit, this functional unit and other functional units.
Above-mentioned functions dependence table can realize in two steps, first shown intermediateness form as shown in table 1 is generated, suppose to determine that it comprises functional unit A00 by traverse user requirement documents in certain software to be tested, B00, C00, D00, give one example, when traversing A00, determine this functional unit A00 on technology realizes at B00, realize after C00, and depend on B00 respectively, C00, automatic generation B00 and C00 in the list item of " institute relies on functional unit numbering " that functional unit A00 is corresponding in Table 1 so automatically, other functional units are similar, no longer describe in detail.
Table 1
| Functional unit is numbered | Numbered by dependence functional unit | Rely on functional unit numbering |
| A00 | Empty | B00, C00 (automatically generating) |
| B00 | Empty | Empty |
| C00 | Empty | D00 (automatically generating) |
| D00 | Empty | Empty |
After generation table 1, according to the content in " functional unit numbering " in each list item and " rely on functional unit number ", logically relation generates the content in " being numbered by dependence functional unit " automatically, as shown in table 2.
Table 2
| Functional unit is numbered | Numbered by dependence functional unit | Rely on functional unit numbering |
| A00 | Empty | B00、C00 |
| B00 | A00 (automatically generating) | Empty |
| C00 | A00 (automatically generating) | D00 |
| D00 | C00 (automatically generating) | Empty |
Like this, the dependence between each functional unit has just been embodied in table 2, namely function dependence table, a function dependent tree just can be constructed according to this, the node of this function dependent tree is each functional unit, line between node embodies the dependence between each functional unit, and this dependence can be embodied by the sequence of positions of each node of function dependent tree.Such as can be embodied by bottom-up order, such as, according to bottom-up order, present node depends on the node of its low one deck, and in table 2, the dependence of each node can be as shown in Figure 2 a.Also can be embodied by the form of arrow points, such as, the node that present node is pointed to by it rely on, in table 2, the dependence of each node can be as shown in Figure 2 b.
Above-mentioned steps 101 and step 102 can perform in advance.
Step 103: when carrying out regression test, from the functional unit of amendment, the functional unit depending on amendment is searched in function dependent tree, and depend on the functional unit of the functional unit respectively found, using the functional unit of amendment and all functions unit that finds as regression test scope.
That is, in function dependent tree from the functional unit of amendment, according to by dependence successively locating function unit.If function dependent tree is according to bottom-up sequential build, then all functions unit according to bottom-up sequential search Existence dependency relationship from the functional unit of amendment in function dependent tree.
As shown in Figure 2 a, suppose that the functional unit revised is D00, be then C00 according to bottom-up sequential search to the functional unit with its Existence dependency relationship in function dependent tree, searching with the functional unit of C00 Existence dependency relationship is A00 again, then using D00, C00 and A00 as regression test scope.
As shown in Figure 2 b, suppose that the functional unit revised is D00, then in function dependent tree, according to the points relationship of arrow, determine that the functional unit that D00 points to is C00, then search C00 point to functional unit be A00, therefore using D00, C00 and A00 as regression test scope.
After determining regression test scope, determine as test case corresponding to each functional unit of regression test scope, adopt these test cases to perform regression test, this partial content no longer describes in detail.
