Amount constructs measurement system based on the quantitative composite metric.
It include the mapping relations of quantitative information demand in measurement system.In order to be based on unifying in development project measurement
Degree amount thought designs measurement model of the invention, therefore, proposes from the angle of test item process and test product quality multiple
Right amount, clearly measurement hierarchical relationship, generate measurement system, and then establish measurement model.When generating measurement system, specifically
Ground, firstly, process measurement and product measurement in Extraction and determination information requirement, for each letter in quantitative information requirement
Breath demand measures the measurement target of information requirement, obtains quantitative multiplicity according to the measurement index of information requirement
Amount;It is then determined that the calculation formula of quantitative composite metric, arranges information requirement, measurement index, measurement target, quantitative multiplicity
Mapping relations between amount and calculation formula.The process for repeating above-mentioned generation mapping relations, obtains quantitative information demand
Quantitatively mapping relationship, and using Quantitatively mapping relationship as measurement system.
In the specific implementation process, comprehensively consider and process measurement and the product measurement of Software Testing Project are covered entirely
Lid proposes the measurement system generated based on quantitative information requirement, wherein quantitative information requirement specifically includes: understanding software
The rule of test item changes in demand ensures that the quality of delivered product meets the requirements, provides rule for similar projects estimation and decision
Mould reference, be similar projects estimation and decision provide progress reference, for similar projects estimation and decision provide workload refer to, skill
The monitoring of art ability.In this way, can be to determine 10 measurement targets for quantitative information requirement, and then according to this 10 measurement targets
To generate measurement system.
It should be noted that due to the measurement target of information requirement " providing scale reference for similar projects estimation and decision "
" evaluation item scale " corresponding measurement index be it is variable, test case scale deviation can be divided into and testing requirement scale is inclined
Difference, therefore, information requirement " providing scale reference with decision for similar projects estimation " can provide 2 kinds of different measurement targets,
That is the first evaluation item scale, the second evaluation item scale;And information requirement " provides progress ginseng for similar projects estimation and decision
Examine " the corresponding measurement index of measurement target " monitoring software testing progress " be also it is variable, milestone schedule variance can be divided into
Rate and schedule deviation rate, therefore, information requirement " providing progress reference with decision for similar projects estimation " can provide 2 kinds it is different
Measure target namely the first monitoring software testing progress, the second monitoring software testing progress;And information requirement " ensures to deliver and produce
The quality of product is met the requirements " measurement target " defect of monitoring evaluation course with closing situation " corresponding measurement index is also can
Become, process evaluation defect concentration can be divided into and evaluation defect averagely closes number of days, therefore, information requirement " ensures delivered product
Quality meet the requirements " can provide 2 kinds of different measurement targets namely first monitoring evaluation course defect and close situation,
The defect and closing situation of second monitoring evaluation course.Wherein it is possible to indicate that information requirement, measurement refer in the form of table
Mapping relations between mark, measurement target, multiple composite metrics and calculation formula, in conclusion based on quantitative information requirement
The measurement system of generation is as shown in table 1.
Table 1
2012, measurement system is normalized, obtains measurement model.
The case where due to each composite metric in measurement system, is different, and lays particular emphasis on different software metrics dimensions, can
Poorer than property, some composite metric dimensionless (such as workload uses deviation ratio), some composite metrics have dimension (such as defect concentration
Dimension is a defect/KLOC), without comparativity.In order to be integrated into a Xiang Zhibiao, it is necessary to be included in the compound of index for all
Measurement goes dimension, the normalization numerical value for each composite metric being comparable, and then can just apply in calculating.Separately
Outside, the order of magnitude of the dimensionless number of each composite metric is identical, at most differs 1 order of magnitude.If each composite metric number
Value differs greatly, it may occur that big data " floods " the case where small data (i.e. small data, which is ignored, disregards), obtained normalization number
Value can not just reflect the contribution of the composite metric of " being flooded ".In conclusion the physics of the dimensionless number of each composite metric
Meaning is obvious, meets the cognitive law and visual sense of people, therefore, by the way that measurement system is normalized, obtains
Measurement model.
In this way, measurement system to be integrated into the index value formula of a reflection project entirety state of progress, thus subsequent
The integrated index that the assessment project of target software is calculated based on the index value formula is realized by the assessment to integrated index
Assessment to assessment project.Specifically, firstly, obtaining the quantitative weighted value of Quantitatively mapping relationship in measurement system respectively and quantifying
Parameter value, namely according to the attention rate and importance of composite metric in measurement system, to multiplicity different in measurement system
Amount assigns different weights.Subsequently, based on the sum of products of quantitative weighted value and quantitative composite metric value, building index value is public
Formula, using index value formula as measurement model.Wherein, the integrated index value being calculated according to index value formula is absolute number
Value, dimensionless.During practical application, being expressed as follows for index value formula is stated shown in formula 1 in the measurement model of foundation.
Formula 1:
Wherein, V is integrated index value, value range [0,1];αiFor the weighted value of each composite metric, value range
[0,1];βiFor the parameter value of each composite metric, value range [0,1];N is to be included in integrated composite metric item number, N >=
1;Which composite metric i indicates, and value is from 1 to N.
It should be noted that the β in formula (1)iFollowing four situation can be further divided into:
I class: the parameter value of composite metric inherently positive rate, as a percentage, composite metric are a kind of forward directions
It measures (i.e. metric is the bigger the better).Such as testing requirement coverage rate, value range [0,1].Such situation is most simple, directly takes multiple
The parameter value of right amount itself.
II class: the parameter value of composite metric inherently deviation ratio, as a percentage.Whether it overgauge or bears
Deviation is all above the expection of project, can all affect to project, therefore will consider.Solution takes deviation ratio
Absolute value.In order to guarantee value range [0,1], it is also necessary to the minimum value to take absolute value with 1.It is a kind of anti-in view of deviation rate metric
It is negative effect to project bring to measurement (i.e. the absolute value of metric is the smaller the better), it is therefore desirable to it is influenced to deduct,
Solution is that minimum value is subtracted from 1.It is noted that user demand volatility can also be included into II class.
III class: the parameter value band dimension of composite metric is indicated, composite metric is a kind of reverse metrics with specific value
(i.e. metric is the smaller the better).If the defect concentration of project is 10 defect/KLOC, the smaller quality of defect concentration is better.To this
A little composite metrics must go dimension.Solution is to set its target value as benchmark (Benchmark) value, takes composite metric
Parameter value and a reference value ratio.In order to guarantee value range [0,1], it is also necessary to take the minimum value of ratio and 1.In view of multiple
Right amount is a kind of reverse metrics, it is therefore desirable to be negatively affected deduction, solution is that minimum value is subtracted from 1.
IV class: the parameter value band dimension of composite metric indicates that composite metric is a kind of positive measurement with specific value
(i.e. metric is the bigger the better).As project productivity be 10LOC/ people when, productivity is bigger, and efficiency is higher.To these multiplicities
Amount must go dimension.Solution is to set its target value as a reference value, takes the ratio of parameter values and a reference value.In order to
Guarantee positive result, needs to subtract 1 from ratio.In order to guarantee that value is positive value, need to take its maximum value with 0.In order to protect
Demonstrate,prove the value range [0,1] of final result, it is also necessary to be maximized the minimum value with 1.
Therefore, after comprehensively considering above-mentioned four kinds of situations, being expressed as follows for index value formula states public affairs in the measurement model of foundation
Shown in formula 2.
Formula 2:
β1i=Ri, i=1 ..., N1
β2i=1-M in 1, | D Ri|, i=1 ..., N2
0≤αji≤ 1, i=1 ..., Nj;J=1 ..., 4
0≤βji≤ 1, i=1 ..., Nj;J=1 ..., 4
Wherein, V is integrated index value, value range [0,1];α1iFor the weighted value of I class composite metric, value range
[0,1];α2iFor the weighted value of II class composite metric, value range [0,1];α3iFor the weighted value of III class composite metric, value model
Enclose [0,1];α4iFor the weighted value of IV class composite metric, value range [0,1];β1iFor the parameter value of I class composite metric, take
It is worth range [0,1];β2iFor the parameter value of II class composite metric, value range [0,1];β3iFor the parameter of III class composite metric
Value, value range [0,1];β4iFor the parameter value of IV class composite metric, value range [0,1];N1It is I class multiplicity quantifier
Number, N1≥1(N1When being 0, it is not included in formula, the same below);N2It is II class composite metric item number, N2≥1;N3It is III class composite metric
Item number, N3≥1;N4It is IV class composite metric item number, N4≥1;RiIt is the positive rate of I class composite metric;DRiIt is II class composite metric
Deviation ratio;NQiIt is the reverse metrics value of III class composite metric;It is the reverse metrics a reference value of III class composite metric
(target value);PQiIt is the positive measurement value of IV class composite metric;It is the positive measuring standard value of IV class composite metric
(target value).
It should be noted that in β3iAnd β4iIn, when parameter values are identical as a reference value, there is singular point: β3iAnd β4i
Value is 0, i.e., parameter contributes index zero.In charter, index is usually to assign index in the form of " >=" or "≤", when
When parameter values are exactly equal to a reference value, target is also had been carried out, pays attention to such situation in assessment.
Respectively as an example to above-mentioned four kinds of situations, as shown in table 2:
Table 2
Pass through above-mentioned algorithm, the product of the α value that the data of four kinds of situations in table 2 are calculated, β value and α value and β value
As shown in table 3:
Table 3
The measurement model that the formula 2 obtained according to above content is established is more comprehensively, more completely than any single dimension index
Ground reflects development of projects state, and measurement is measured and be segmented better than binary, and measurement results are finer, more objective, can be used as uniformly referring to
Mark comes evaluation item performance (as long as setting evaluation criteria and criterion in advance), has open and scalability, can be at any time according to institute
The additional parameter measurement of the composite metric needed.
202, the metric data of acquisition target software assessment project, is input to measurement model for metric data.
In embodiments of the present invention, after generating measurement model, the measurement of target software assessment project can be acquired
Metric data is input to measurement model, realizes the assessment to target software by data.It wherein, can be with when acquiring metric data
The assessment process of target software is monitored, the data conduct for the project assessed is extracted in entire assessment process
Metric data.Since measurement model is generated based on quantitative information requirement, metric data needs and quantitative information
The quantitative composite metric that demand generates corresponds, to guarantee that measurement model can carry out normalizing to the metric data of input
Change processing.
203, it is based on measurement model, metric data is normalized, the integrated index value of metric data is generated.
In the present invention, since measurement model is generated based on index value formula, by metric data degree of being input to
After measuring model, it is based on the index value formula, can realize and metric data is normalized, to generate the measurement number
According to integrated index value.Specifically, between the position and parameters due to defining parameters in index value formula
Calculated relationship therefore by metric data according to the instruction of measurement model, successively fill in the index value formula of measurement model,
And the value of the index value formula after filling metric data is calculated, thus using value as integrated index value.Continue with above-mentioned
It is illustrated for the example of table 3 in step 201, is α value, β value and the α value and β value of metric data as shown in table 3
Product, in this way, calculating the product of α value, β value and α value and β value, available integrated index value V=0.68.
204, evaluation criteria is obtained, the target scale that integrated index value maps in evaluation criteria is determined, by target mark
Spend the assessment result as target software assessment project.
In embodiments of the present invention, it after generating integrated index, can be realized based on the integrated index to mesh
