Description
Technical field
The present invention relates to computer software fields, in particular to a kind of code tester coverage rate statistics reallyDetermine method and device.
Background technology
In correlation technique, the code coverage in test refers to after operation test case, the code having coveredLine number, and then the lines of code that adopts the lines of code having covered totally to comprise divided by tested object is this surveyThe code coverage of examination. Suppose that tested object is a function, and this function has 100 line codes altogether, works as instituteAfter some test cases are finished, cover 60 line codes, and also had the code of 40 row not to be covered to,The code coverage of this function is 60% so.
It should be noted that, the code line of mentioning in above-mentioned example is only a kind of comparatively conventional metric form.
To severally be introduced for the metric form that represents code coverage degree conventional below:
1) statement covers (StatementCoverage)
The row that is otherwise known as covers (LineCoverage), and section covers (SegmentCoverage), and basic block covers(BasicBlockCoverage), this for the most frequently used be also modal a kind of coverage mode, it is measured in tested codeWhether each executable statement has been performed. Here refer to " executable statement ", therefore, just can not comprise asThe header file statement of C Plus Plus, code annotation, null etc.
The code that this kind of coverage mode only added up to carry out has been performed how many row. It should be noted that separatelyThe brace { } of a line is also usually entered by statistics. Statement covers and is conventionally identified as " the most weak covering ", and it is only negativeDuty covers the execute statement in code, but without the combination of considering various branches. The defect of this statement coverage mode existsIn: expend time in and energy, still, the test effect obtaining not obvious, is difficult to find to exist in code testerProblem.
2) judge and cover (DecisionCoverage)
The branch that is otherwise known as covers (BranchCoverage), and all borders cover (All-EdgesCoverage), itsFor whether tested the completing of branch of each judgement of tolerance program.
3) Condition Coverage Testing (ConditionCoverage)
For measuring each subexpression result true of judgement and whether false is tested completes. For example: statement ifA > 0orb > 0, this is a combination condition, if condition is set up, has both likely met a > 0, also likely meetB > 0, the two is called as the sub-condition of whole conditional statement. In some cases, tester need to clearly know softPart run time version is to complete test because which sub-condition meets actually.
It should be noted that, " Condition Coverage Testing ", compared with " judge and cover ", implementation dynamics is stronger, and its reason is:Condition Coverage Testing need to make the each decision condition in each decision process all obtain two different result of determination; PhaseInstead, judge and cover be more concerned about whether whole condition is set up, and cannot guarantee that each decision condition has all obtained twoDifferent result of determination.
4) path covers (PathCoverage)
Be otherwise known as and assert covering (PredicateCoverage), its for each branch of measuring function whether byComplete, all possible branch is all performed one time. But, in the time having multiple branches nested in execute statement,Need to carry out permutation and combination to multiple branches, easily cause test path along with the quantitative indicator rank of branch increases.
At present, in the time of performance element test operation, code coverage is usually used to as weighing the fine or not index of test;Even, once code coverage had been used as to the important performance assessment criteria of test assignment performance.
In order completing, code coverage to be tested, multiple testing tool to be provided in correlation technique, for example: pythonThe storehouse of the coverage of language, the detection to code coverage all supported in JCov storehouse and the lpc language of java language.
Subversion (referred to as SVN) is the version control system of an open source code. At present, the overwhelming majorityOpen source software all uses SVN as code release management software.
Subversion is as Version of new generation, its with respect to other version managements such as RCS, CVSSoftware, has adopted unique branch management system, thereby in free Version Control service on the internet, occupies leadingStatus.
The version repository of Subversion can be by access to netwoks, thereby user can be carried out on different computersOperation. From to a certain degree, allow user in space separately, to revise and manage same group of data and can promote groupTeam's cooperation. Because amendment is no longer that single line carries out (being serial operation), therefore development progress is also significantly improved. ThisOutward, due to all versioned of all work, also just needn't worry because maloperation affects software development quality, because ofThis, if there is wrong change operation, as long as cancel wrong change operation. In addition, some Version ControlSystem itself is also software configuration administrative system (SCM), and this system, through exquisite design, is used for managing speciallySource code tree, and possess many characteristics relevant with software development, for example: to the support of programming language, provide journeyOrder the build tool. But Subversion is not such system, it is a general-purpose system, can manage and appointThe file set of what type.
Existing coverage rate instrument can only be described the coverage condition to certain file entirety, input need test single orMultiple files, then carry out the judgement test of various conditions, and final output covers result.
And in the process of product maintenance, programming personnel or attendant have conventionally just revised some and have existed veryA part of content of code of a specified duration. For example, need to modify to file A because of function adjustment, suppose file AOriginally comprised 1000 row logical codes, and this amendment is only in file A, to increase by 100 row logical codes, therefore,What this time code tester operation was in fact only paid close attention to is the coverage condition of this 100 row logical code, and is not wholeThe coverage condition of 1100 row logical codes.
The solution of easily expecting in correlation technique is by this 100 row logical code separating treatment from file A, singleSolely be set to file A1, and then file A1 is tested. But true not so simple, its reason is:This 100 row logical code is dispersed in file A in original 1000 row logical codes, not easily separated; Moreover,Just this 100 row logical code can be separated, this 100 row logical code is owing to being not a complete logicUnit, so cannot independently carry out.
For above-mentioned problem, effective solution is not yet proposed at present.
