Which member function there occurs that code is changed in class files, and the plurality of class nodes can be analyzed successively.
For each class nodes in the first metadata set, by taking class nodes 1 as an example, test case screening unit can
To be searched and the class nodes 1 target class nodes of the same name in the second metadata set, if in the second metadata set
Search less than target class nodes, then it is the brand-new class nodes of current compiling generation to illustrate the class nodes 1, i.e., should
All member functions under class nodes 1 there occurs that code is changed.Now, test case screening unit can be by the class
The change attribute of all member functions is labeled as the first attribute (such as True) under node.Member function A is included with class nodes 1
Exemplified by member function B, the change attribute that can mark member function A and member function B is True.By the first attribute to generation
The member function that changes of code is marked, can be in order to subsequently obtaining the confirmation and acquisition to these member functions.
And if finding target class nodes in the second metadata set, then illustrate under the class nodes 1 at least
Code change does not occur for one member function.Now, test case screening unit can be further right by performing step 304
The class nodes 1 are analyzed, to determine the situation of code change.

Exemplified by member function B, the change attribute that can mark member function A and member function B is False.
And if the summary info that includes of the class nodes 1 is different with the summary info that target class nodes are included, then
Illustrate that 1 time at least one member function of the class nodes there occurs that code is changed.Now, test case screening unit can be with
Further all method nodes under the class nodes 1 are analyzed, are which member function there occurs code to determine
Change.
In the embodiment of the present invention, under the method nodes under the class nodes 1 and target class nodes
The process that method nodes carry out variance analysis may comprise steps of a to b：
A, for each method nodes under the class nodes 1, read the title of the method nodes, this second
Target method nodes are searched in metadata set, target method nodes are identical with the title of the method nodes；If looked into
Target method nodes are can not find, then by the change attribute of the corresponding member function of method nodes labeled as first category
Property；
In the embodiment of the present invention, due to there is multiple method nodes under each class nodes, and each method nodes pair
A member function is answered, can be to the class in order to determine that 1 time which member function of the class nodes there occurs that code is changed
Multiple method nodes under node 1 are analyzed successively.
For each method nodes under the class nodes 1, by taking method nodes 1 as an example, test case screening unit
It can be searched in the second metadata set and the method nodes 1 target method nodes of the same name, if in the second metadata
Concentrate and search less than target method nodes, then illustrate that the corresponding member function of method nodes 1 there occurs that code is changed.
Now, test case screening unit can be by the change attribute of the corresponding member function of method nodes 1 labeled as the first category
Property (such as True).By taking the corresponding member function A of the method nodes 1 as an example, the change attribute that can mark member function A is
True。
And if finding target method nodes in the second metadata set, then illustrate that the method nodes 1 are corresponding
Member function has been likely to occur code change.Now, test case screening unit can be by performing step b, further really
Whether the fixed corresponding member function of method nodes 1 there occurs that code is changed.
If b, target method nodes are found, according to the byte code sequence of the method nodes and the target
The byte code sequence of method nodes, calculates Levenstein distance, if Levenstein distance is more than or equal to pre- gating
Limit value, then be labeled as first attribute, if the Levenstein by the change attribute of the corresponding member function of method nodes
Distance is less than predetermined threshold value, then the change attribute of the corresponding member function of method nodes is labeled as into second attribute.
In the embodiment of the present invention, Levenstein distance can be used for weighing the similarity between two byte code sequences.Survey
Example screening unit on probation, can after it is determined that there is the target method node of the same name with method nodes 1 in the second metadata set
According to assignment algorithm, to calculate between the byte code sequence of method nodes 1 and the byte code sequence of target method nodes
Levenstein is apart from D.
If D is more than or equal to predetermined threshold value, illustrate the byte code sequence and target method of method nodes 1
Similarity is relatively low between the byte code sequence of node, it is believed that the corresponding member function of method nodes 1 there occurs code
Change.In this case, test case screening unit can mark the change attribute of the corresponding member function of method nodes 1
For the first attribute (such as True).
