In step S101, obtain respectively the test case of each code line association, this test case covers the code line associated with it.
In the present embodiment, before step S101, can be by all test cases of the baseline test case library set of all test cases of baseline version code tester (for) be carried out to coverage rate analysis, thereby get the code line of each source file to the mapping relations of this baseline test case library, every line code of knowing source file is all covered by which test case, thus, according to the mapping relations that get, in step S101, can get respectively the test case of each the code line association in each source file, in the incidence relation of this " code line-test case ", being used to indicate each code provisional capital is covered by which test case, be that the associated test case of each code line all covers the code line associated with it.
It should be noted that, in embodiments of the present invention, coverage rate analysis can adopt corresponding coverage rate statistical tool to complete according to the difference of code programming language used, at this, is not used in restriction the present invention.
In step S102, when having code line that change occurs, extract the test case of this code line association.
In the present embodiment, can to the code of new and old two versions, compare by for example diff order, obtain the modification information of new version of code, when finding that there is code line, change, comprise newly-increased, when deleting or revising, extract the associated test case of code line that change occurs, for carrying out regression test.
For example, when modification information indication has code line deleted, extract the associated test case of deleted code line and carry out regression test; When modification information indication has code line to be modified, also extract the associated test case of code line being modified and carry out regression test.
Therefore, in the present embodiment, by test case is screened, in regression test, only need test can reach the test purpose of expection completely with the test case that the code line that change occurs is associated, under the prerequisite that guarantees test case validity, greatly improved testing efficiency.
As one embodiment of the present of invention, due to when code generation increases code line newly or revises the alteration of code line, may occur that the code line that occurs to change possesses the situation of the test case associated with it in addition, now, as shown in Figure 2, the embodiment of the present invention also comprises:
Step S103, if do not have test case associated with the code line that change occurs, feeds back the information of this code line.
In the present embodiment, the information of code line comprises the source filename of this code line place source file and the line number of this code line, by feeding back the above-mentioned information of this code line, the test case that tester can be associated according to the newly-increased code line with there is change of above-mentioned information, has effectively avoided the omission to function logic in test.
For example, for newly-increased code line, test case in baseline version use-case storehouse all cannot cover this code line, need to feed back the filename of newly-increased code line place source file and the line number of code line to tester, to point out the newly-increased corresponding test case of tester to carry out regression test.
