Code.
Step S30: default automatic test cases are executed, the covering of the source code is obtained by the code of pitching pile
Rate report.
It will be appreciated that in order to test the source code, to obtain covering for the source code according to test result analysis
The report of lid rate, can write multiple UI automatic test cases previously according to the function of the destination application, i.e., described default
Automatic test cases, by the way that in the UI automatic test cases that execution Java language is write in a browser, UI automates foot
Originally the survey of public module (such as homepage account page), each service line (service lines such as oxygen is borrowed or i is borrowed) functional sequence is specifically included
Case script on probation, can automatic imitation manually operated on APP, click button or input etc., after enabling JSCover service, execute
The default automatic test cases obtain the report of H5 code coverage, i.e., the coverage rate report of the described source code.The present embodiment
In, before the step S20, further includes: the service line functional sequence for obtaining the destination application, according to the service line
Functional sequence writes default automatic test cases.
In the present embodiment, the step S30, comprising:
Default automatic test cases are executed, test result is obtained；
According to the test result, reported by the coverage rate that the code of pitching pile obtains the source code.
It should be noted that can be generated by writing the build mode of report report as a result, generate report, by with
Lower step operation, for example, being respectively there are three the ec files of the test result of the execution default automatic test cases
Yyb1.ec, yyb2.ec and yyb3.ec.The classes.zip that coverage rate is packaged in result is dropped into template root and is solved
Pressure；The address svn and version number when according to packing, remove source code and are put into src catalogue, svn is the abbreviation of Subversion, is
The version control system of one open source code；Ec file (yyb1.ec, yyb2.ec and yyb3.ec) is all dropped into template root
In catalogue；Build_property file is modified, title is write as into value (removing ec suffix)；Build file, such as nothing
Path change, it is basic not have to modify, the build_group that build file takes, respectively<group name=" YYB ">,<
Group name=" plugin_power_save " >；Ant is executed, report catalogue will generate；After report catalogue generates,
The coverage rate report can be obtained by entering to execute index.
In the concrete realization, js code coverage can be obtained by establishing JSCover service, JSCover service is realized
Principle is exactly to realize to H5 code pitching pile, is ordered as follows: java-jar target/dist/JSCover-all.jar-ws--
Document-root=doc/example--report-dir=target；After enabling JSCover service, executes automation and survey
Training sheet obtains the report of H5 code coverage.
Step S40: extract that target is not carried out code and corresponding target is not carried out duration from coverage rate report.
It will be appreciated that the coverage rate report includes performing which code, the time that code executes and code to execute
The information such as a result can then extract from coverage rate report and be not carried out code.For row coverage rate, from the coverage rate report
Announcement finds out that a total of first quantity row has covered the second quantity row.The coverage rate report is analyzed by executing java script
And corresponding source code, show which code is not carried out in the source code, and generate how many days how many row are not used
It arrives, i.e., the described target is not carried out duration, generates dead code analysis report.Java is a kind of programming language, can write Java
Script is reported coverage rate and source code carries out processing analysis, specifically includes in the file to coverage rate report and source code
Hold the processing of character string and create the processing logic of object, is realized especially by bottom code, the purpose of the java script
It is the analysis coverage rate report and the source code, to export which code is not carried out.It is described in the present embodiment
Step S40, comprising: coverage rate report and the source code are analyzed by default script, from the coverage rate report
Extract that target is not carried out code and corresponding target is not carried out duration in announcement.
It should be understood that being directed to extra cascading style sheets (Cascading Style Sheets, write a Chinese character in simplified form CSS) pattern generation
Code can also analyze never call after which id style definitions by java script, not used layout pattern or picture resource etc., from
And it can also obtain CSS dead code analysis report.For example, CSS be defined pattern daohang, caidan, leibiao and
Biaoti, but only used in the page in implementation of test cases: caidan and biaoti, that is to say, that also
The two model codes of daohang and leibiao are not carried out, then this extra two model code is that the target is not held
Line code.
Step S50: being not carried out duration using the target and be not carried out code to the target and screen, obtain target without
Use code.
It should be noted that default execution duration rule can be set in conjunction with type of code according to previous experiences, it is described pre-
If executing duration rule includes that the corresponding code of each H5 code executes duration threshold value, extracted from the default execution duration rule
The target is not carried out the corresponding object code of code and executes duration threshold value out, and the target is not carried out duration and the target
Code executes duration threshold value and is compared, if the target, which is not carried out duration, executes duration threshold value more than the object code,
Assert that the target is not carried out duration and the default execution duration rule match success, the target of successful match is not carried out duration
Corresponding target is not carried out code, that is, is more than that the object code executes the target of duration threshold value to be not carried out duration corresponding
Target is not carried out code, screens as the target dead code.For example, in above-mentioned example, daohang and leibiao the two
Model code is that the target is not carried out code, if the target of the two model codes of daohang and leibiao is not carried out duration
The default execution duration rule can be matched, then the two model codes of daohang and leibiao can be screened as the mesh
Mark dead code.In the present embodiment, the step S50, comprising: obtain default execution duration rule, do not held using the target
Row duration be not carried out from the target filtered out in code meet it is described it is default execute duration rule code it is useless as target
Code.
Step S60: the target dead code is deleted from the source code.
It should be understood that can be by the target dead code from the application program of current version (Application, abbreviation
APP it is deleted in installation kit (AndroidPackage writes a Chinese character in simplified form APK)), to reduce dead code, mitigates the APK of APP
Backpack body product, improves user experience.Such as in above-mentioned example, daohang and the two model codes of leibiao be the target without
With code, by daohang and leibiao, the two model codes are deleted from the APK of the destination application, APK
Volume reduces, and in downloading installation process, the flow of consuming is also accordingly reduced, and the installation waiting time can also reduce, for product
Itself, it is meant that downloading conversion ratio improves, to improve user experience.

Modeling type is not carried out code to the target and screens, and obtains target dead code.
It should be understood that it is based on machine learning in order to improve the screening efficiency and accuracy rate of the target dead code, it can
It obtains a large amount of history test case and executes data, extract sample from history test case execution data and be not carried out generation
Code, sample be not carried out duration and corresponding sample dead code, code is not carried out according to the sample, sample be not carried out duration and
Corresponding sample dead code is trained convolutional neural networks model, obtains default screening model, the default screening mould
Type have passed through a large amount of sample training, so as to accurately filter out dead code.It can be by the way that the target be not carried out generation
Code and the corresponding target are not carried out duration and input the default screening model, export the target dead code.This implementation
In example, before the step S501, comprising: when the sample for obtaining the destination application is not carried out code, sample is not carried out
It grows and corresponding sample dead code；Be not carried out code according to the sample, the sample be not carried out duration with it is corresponding described
Sample dead code is trained convolutional neural networks model, obtains default screening model.
In the present embodiment, before the step S60, further includes:
The source code and the current code version are carried out backup and deposited by the current code version for obtaining the source code

Announcement finds out that a total of first quantity row has covered the second quantity row.The coverage rate report is analyzed by executing java script
And corresponding source code, show which code is not carried out in the source code, and generate how many days how many row are not used
It arrives, i.e., the described target is not carried out duration, generates dead code analysis report.Java is a kind of programming language, can write Java
Script is reported coverage rate and source code carries out processing analysis, specifically includes in the file to coverage rate report and source code
Hold the processing of character string and create the processing logic of object, is realized especially by bottom code, the purpose of the java script
It is the analysis coverage rate report and the source code, to export which code is not carried out.It is described in the present embodiment
Extraction module 40 is also used to analyze coverage rate report and the source code by default script, from the covering
Extract that target is not carried out code and corresponding target is not carried out duration in rate report.
It should be understood that being directed to extra cascading style sheets (Cascading Style Sheets, write a Chinese character in simplified form CSS) pattern generation
Code can also analyze never call after which id style definitions by java script, not used layout pattern or picture resource etc., from
And it can also obtain CSS dead code analysis report.For example, CSS be defined pattern daohang, caidan, leibiao and
Biaoti, but only used in the page in implementation of test cases: caidan and biaoti, that is to say, that also
The two model codes of daohang and leibiao are not carried out, then this extra two model code is that the target is not held
Line code.

Obtain target dead code.
It should be noted that default execution duration rule can be set in conjunction with type of code according to previous experiences, it is described pre-
If executing duration rule includes that the corresponding code of each H5 code executes duration threshold value, extracted from the default execution duration rule
The target is not carried out the corresponding object code of code and executes duration threshold value out, and the target is not carried out duration and the target
Code executes duration threshold value and is compared, if the target, which is not carried out duration, executes duration threshold value more than the object code,
Assert that the target is not carried out duration and the default execution duration rule match success, the target of successful match is not carried out duration
Corresponding target is not carried out code, that is, is more than that the object code executes the target of duration threshold value to be not carried out duration corresponding
Target is not carried out code, screens as the target dead code.For example, in above-mentioned example, daohang and leibiao the two
Model code is that the target is not carried out code, if the target of the two model codes of daohang and leibiao is not carried out duration
The default execution duration rule can be matched, then the two model codes of daohang and leibiao can be screened as the mesh
Mark dead code.In the present embodiment, the screening module 50 is also used to obtain default execution duration rule, utilizes the target
It is not carried out duration and is not carried out to filter out in code from the target and meet the default code for executing duration rule as target
Dead code.
