Detailed Description
In order to make the technical solutions of the present disclosure better understood by those skilled in the art, the present disclosure is further described in detail below with reference to the accompanying drawings and examples.
In which the terminology used in the embodiments of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used in the disclosed embodiments and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
In the following, some terms in the present disclosure are explained to facilitate understanding by those skilled in the art:
the LOC (Line of Code) metric is a measure of the software scale, which represents the number of lines of source Code. Is a common code complexity measuring method at present.
The McCabe measurement method is a complexity measurement method based on program control flow. The McCabe complexity metric is also known as a loop metric. It considers that the complexity of a program depends largely on the complexity of the program diagram. The single sequence structure is the simplest, and the more loops are formed by loops and selection, the more complicated the procedure. The method uses graph theory as a tool, firstly draws a program graph, and then uses the loop number of the graph as a measure value of program complexity.
Covariance, Covariance (Covariance), is used in probability theory and statistics to measure the overall error of two variables. Variance is a special case of covariance, i.e. when two variables are the same. Covariance represents the error of the sum of the two variables. In covariance, define
Figure BDA0002528825430000041
Is the (Pearson) correlation coefficient of the random variables X and Y.
The software complexity measurement is used as an important component of software engineering, and can provide support for the control and degradation of software, the resource allocation of software testing and the development of high-quality software. The software complexity measurement is used as an important branch of the software measurement, and the complexity of a software product can be effectively evaluated. The complexity of the software is pre-warned through complexity measurement, so that people can be helped to objectively analyze and evaluate the complexity conditions of different stages of the software life cycle, and certain complexity control and degradation measures are taken to reduce the software defect rate and improve the software quality, but the convenience of quantitatively analyzing the complexity of the open source software is basically a single complexity measurement method at present, so that the codes cannot be comprehensively evaluated and the test task quantity cannot be estimated, and the test resources cannot be reasonably distributed during testing, so that the efficiency is low; this makes management and risk assessment of software inadequate.
The following describes the technical solutions of the present disclosure and how to solve the above technical problems in specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a distributed software testing method provided in an embodiment of the present disclosure, including:
step S101: dividing the software engineering into a plurality of modules according to a preset minimum test quantity;
step S102: acquiring the test task quantity T of each module; and the number of the first and second groups,
step S103: and arranging test resources for each module according to the test task quantity T of each module.
The disclosed embodiments propose a concept of integration complexity, so-called integration complexity, i.e. the minimum number of tests that must be tested at the time of testing. Firstly, module division is carried out on the whole project, and then the testing task quantity of each module is calculated, wherein the testing task quantity not only comprises the complexity of software, but also needs to consider the requirements of the software project and the resources during actual testing. Therefore, the reasonable allocation of resources is carried out by measuring the task amount of the distributed modules, and the efficiency of the distributed test is improved.
Further, the obtaining the test task amount T of each module includes:
calculating the complexity C of each module;
acquiring a complexity coefficient lambda of software engineering; and the number of the first and second groups,
and calculating the testing task quantity T of each module according to the complexity C of each module and the complexity coefficient lambda of the software engineering.
Because the same test tool has the same test cost for testing different files, the calculation of the complexity coefficient is obtained by testing open source engineering simulation in advance. The workload generated during defect analysis is obtained by judging the engineering complexity of the code to be detected, and is matched with the available resources of the system, so that the test resources of the distributed defect detection system are utilized to the maximum extent.
Further, the obtaining of the complexity coefficient λ of the software engineering includes:
selecting a preset number of modules from the plurality of modules as modules to be tested;
acquiring a memory D consumed by testing each module to be tested; and the number of the first and second groups,
and calculating the complexity coefficient lambda of the software engineering according to the complexity C of each module to be tested and the memory D consumed by testing the module to be tested.
With the increasing complexity of software engineering, the software engineering is increasingly huge, and the huge amount and high complexity of large engineering codes are the most basic characteristics, so that the preprocessing of the codes to generate intermediate information has higher requirements on the internal memory, and the higher the complexity of the codes is, the larger the memory occupied by the codes is. Therefore, when large-scale software is subjected to distributed computation, not only the complexity of software engineering itself but also the requirement on a memory during actual testing are considered. Dividing the software engineering into a plurality of modules; selecting a preset number of modules to be tested; calculating a complexity coefficient according to the complexity of each module to be tested and the memory consumed by testing the module; and calculating the test task quantity of each module to be tested according to the complexity coefficient and the complexity of each module, and reasonably arranging the test task quantity of the whole software engineering. The efficiency of distributed software testing is improved, and the codes are comprehensively evaluated from multiple angles, so that the distributed software testing system is more comprehensive.
Further, the preset number of the modules to be tested is more than or equal to 3.
The complexity coefficient can be calculated by performing simulation test on open source engineering in advance, and can also be tested in real time, and in order to improve the accuracy of the complexity coefficient, enough samples are required during testing, so that the preset number of the modules to be tested is generally 3-10.
Further, the complexity C of each module is calculated by the following formula:
Ci=ω1LOC(i)+ω2McCabe(i),ω12=1
wherein, CiComplexity of the i-th module, 1<i is less than or equal to m, m is the total number of modules divided by the software engineering, LOC (i) is the single complexity of the ith module calculated by the LOC measurement method, McCabe (i) is the single complexity of the ith module calculated by the McCabe measurement method, omega1The weight, ω, of relative importance of the LOC metric2Is the weight of relative importance of the McCabe measurement method.
In order to improve the credibility of the integration complexity, a credibility evaluation index is defined, respective single complexity is obtained by calculation from the two aspects of the LOC measurement method and the McCabe measurement method, and the comprehensive complexity of the LOC measurement method and the McCabe measurement method is obtained according to the weight of relative importance.
Further, the complexity coefficient λ of the software engineering is calculated according to the complexity C of each module to be tested and the memory D consumed by testing the module to be tested, and the formula adopted is as follows:
Figure BDA0002528825430000071
wherein Cov (C, D) is covariance, and the calculation formula is:
Figure BDA0002528825430000072
wherein n is the total number of the modules to be tested, CiComplexity of the ith module under test, DiTo test the memory consumed by the ith module under test,
Figure BDA0002528825430000073
represents the average of the complexity of all the modules under test,
Figure BDA0002528825430000074
the average value of memory consumed by testing all the modules to be tested is shown.
D (c) and d (d) represent the complexity and variance of the consumed memory, respectively. The variance is a mature calculation method used for describing the degree of correlation between two variables, if the degrees of deviation of the two variables from the mean are more consistent, the numerical value is larger, and through the relationship between the complexity C and the two dependent variables of the memory D consumed during testing, the complexity coefficient, namely the (Pearson) correlation coefficient of the complexity and the consumed memory can be obtained.
Further, the test task quantity T of each module is calculated according to the complexity C of the module and the complexity coefficient λ of the software engineering, and the formula is as follows:
Ti=λ*Ci,λ>0
wherein, TiTest task volume for the ith module, CiComplexity of the i-th module, 1<N is less than or equal to i, n is the total number of the modules to be tested, and lambda is the complexity coefficient of the software engineering.
The complexity coefficient is a positive number because the larger the general software complexity value is, the higher the memory consumed during testing will be. The execution strategy of the distributed defect detection method of the test task can be given through the obtained test task amount of all the modules, and the modules with large task amount are distributed to the nodes with sufficient resources for testing so as to reasonably promote the execution of the test task.
