DETAILED DESCRIPTION


FIG. 1 illustrates a system 5 for inspecting source code during software development, in accordance with embodiments of the present invention. Software development may be expressed as a V-shaped lifecycle model, starting from a requirements specification followed by system design, implementation, unit testing, system testing, and user acceptance testing. During software development, source code is inspected for defects. Source code is defined herein as program instructions (in an original format) that must be translated by a compiler, interpreter, or assembler into object code. One method used to determine defects in source code includes measuring software metrics for each source code file (i.e., of multiple source code files) and based on the measured metrics, source code files comprising defects may be located. A software metric is defined herein as a measure of a property or specification of a portion of software. Software metrics may include, inter alia, line of code metrics (e.g., number of lines, number of operators, number of line of comments,) error count metrics (e.g., number of errors and error density,) McCabe software metrics (e.g., cyclomatic complexity and decision density,) etc. Multiple metrics may be used for selecting source code files for inspection. System 2 enables an evaluation function used to analyze multiple metrics and compares an obtained score with a pre-set threshold in order to select source code files for inspection. System 2 provides a means to adjust an evaluation function of a source code file for inspection.


System 5 of FIG. 1 comprises a computing apparatus 8a connected to a computing system 10 through a network 7. Network 7 may comprise any type of network including, inter alia, a local area network, (LAN), a wide area network (WAN), the Internet, etc. Computing apparatus 8a may comprise any type of computing apparatus including, inter alia, a personal computer, a laptop computer, a computer terminal, etc. Computing apparatus 8a may comprise a single computing apparatus or a plurality of computing apparatuses. Computing apparatus 8a is used by end users for communicating with (e.g., selecting a source code file, selecting a past project, viewing source code files, viewing evaluation score graphs as illustrated in FIG. 2, etc) computing system 10. Computing system 10 may comprise any type of computing system(s) including, inter alia, a personal computer (PC), a server computer, a database computer, etc. Computing system 10 is used to retrieve data from computing apparatus 8a and using multiple metric to inspect source code for defects. Computing system 10 comprises a memory system 14. Memory system 14 may comprise a single memory system. Alternatively, memory system 14 may comprise a plurality of memory systems. Memory system 14 comprises a software application 18 and a database 12. Database 12 comprises all retrieved data (i.e., retrieved from computing apparatus 8a such as, inter alia, source code files, metrics data, etc) and any generated data (e.g., evaluation scores, graphs, parameter values, etc). Software application 18 enables a method to calculate an evaluation score based on multiple metrics for source code files. The evaluation score is determined for each source code file and calculated employing an evaluation function. Parameter values for the evaluation function are calculated based on the source code file specified by a user. Parameter values giving a worst evaluation score concerning the source code file specified by the user are found with linear programming.



FIG. 2 illustrates a user interface 200 used to enable system 5 for inspecting source code and determining defects in the source code, in accordance with embodiments of the present invention. User interface 200 may be implemented and presented to a user via a display/monitor (e.g., LCD, CRT, Plasma, laser, etc) that is comprised by computing apparatus 8a. User interface 200 comprises a first display section 202, a second display section 204, and a third display section 208. First display section 202 comprises a graph 202a comprising an evaluation score (i.e., on the Y-axis) for each file (i.e., on the X-axis) of a project to be inspected. Second display section 204 comprises a graph 204a comprising an evaluation score (i.e., on the Y-axis) for each file (i.e., on the X-axis) of an inspected project aaa. Third display section 208 comprises an inspected project list 208a.


Software application 18 (of FIG. 1) performs the following functions associated with user interface 200:


1. A user may confirm source code files included in a project for inspection (or a project implemented in the past) using first display section 202 or second display section 204. For example, the user may select (e.g., by using a mouse to clicks any one of points 202b or 204b) a source code file. The selected source code file is called a reference source code file. Software application 18 enables a method to change parameter values for an evaluation function in response to a selected reference source code file.


2. First display section 202 and second display section 204 provides a function for selecting a reference source code file. When a source code file is selected, an editor is enabled.


3. A user may confirm the names of past projects (or their profiles) using third display section 208 and selects a project. The selected project is called a reference project. Based on all source code files included in the reference project, an evaluation function that is used for the target project for inspection is determined. Using linear programming, parameter values are found so that the sum of evaluation scores of all source code files included in the reference project will be the worst. By employing the evaluation function based on parameter values, an evaluation score of each source code file in the project targeted for inspection is calculated.


User interface 200 in combination with computing system 10 of FIG. 1 enables the following functions:


1. Displaying a list of inspected projects in third display section 208.


2. Determining parameter values for an evaluation function in accordance with a source code file specified by a user. The parameter values will generate a worst evaluation score of the source code file based on obtained metrics data.


3. Allowing a user to select a reference source code file by selecting one of points 202b or 204b indicating a source code file.


4. Determining parameter values for an evaluation function based on the reference source code file.


5. Calculating an evaluation score for each source code file of a project for inspection and a reference project and displaying results in the windows in first display section 202 and second display section 204.


6. Determining parameter values for an evaluation function in accordance with the reference project specified by the user. The parameter values are determined such that a sum of evaluation scores of all source code files included in the project will be the worst based on an obtained evaluation function and metrics data.


7. Allowing a user to select a reference project from display section 208.


8. Determining parameter values for an evaluation function based on source code files of the reference project.


9. Calculating an evaluation score for each source code file of the project for inspection and reference project.


The following example illustrates an implementation scenario for enabling a process for inspecting source code during software development:


In this example, it is assumed that a number of the source code files of the project for inspection are represented by I and K metrics are obtained for each source code file. xi,1, . . . , xi,K are given for K metrics of the source code file number i. It is additionally assumed that for each metric, the larger the value, the lower the quality. A relationship between an evaluation score vi of an ith source code file and metrics xi,1, . . . , xi,K is expressed by the following equation 1:

Equation





1







Equation 1 (i.e., an evaluation function) is defined as a weighted sum of metrics and a constant. By changing values of parameters a1, . . . , aK, b (b is a constant), equation 1 expresses various evaluation functions (a linear expression). Alternatively, nonlinear relationships (e.g., a gradual increasing type, a gradual decreasing type, an S-shaped type) may be used. In this case (i.e., by appropriately changing a scale for metrics), they are expressed by a linear expression. In order to calculate parameter values for the evaluation function (i.e., equation 1), it is assumed that the user selects the i0th source code file as a reference source code file. In the following equation 2, the following constraint is introduced: an evaluation score of each source code file is 0 or more and 1 or less and based on the following equation 2, the values of parameters a1, . . . , aK for Equation 1 are calculated.

Equation 2 is used to determine values of parameters a1, . . . , aK so that the evaluation score of the reference source code file will be the maximum (i.e. the worst). After parameter values are calculated, an evaluation score vi for each source code file i (i.e., apart from the reference source code file) is calculated using equation 1. When the user specifies another reference source code file, values of parameters a1, . . . , aK are determined so that its evaluation score will comprise a maximum score. It may be interpreted that an evaluation equation obtained by means of these methods characterizes the defects of the reference source code file. Such an evaluation function may be obtained by a click operation on user interface 200. Each evaluation score for each source code file is calculated using Equation 1 and displayed via user interface 200.


In order to calculate parameter values, a set of source code file numbers comprises the following variables defined as follows:


1. A set R is defined as a collection of source code file numbers of a reference project selected by a user.


2. A set T is defined as a collection of source code file numbers of a project for inspection.


3. A number of source code files I is included in the project for inspection and therefore T={1, . . . , I}. Where both the reference project and project for inspection are a combined a set of source code file numbers expressed as T∪R .


The following constraint (with respect to equation 3 below) is introduced: an evaluation score for each source code file is 0 or more and 1 or less and based on equation 3 below, the values of parameters a1, . . . , aK for Equation 1 are calculated.

Equation 3 is used to calculate values of parameters a1, . . . , aK so that the sum of evaluation scores in the reference project will be a maximum (i.e. the worst). After parameter values are calculated, an evaluation score vi for each source code file i of the reference project is determined by using Equation 1. When the user specifies another reference project, values of parameters a1, . . . , aK are determined so that the sum of its evaluation scores will comprise a maximum.



FIG. 3 illustrates a flowchart describing an algorithm used by system 5 of FIG. 1 for implementing a first method for inspecting source code during software development, in accordance with embodiments of the present invention. In step 301, a computing system (e.g., computing system 10 of FIG. 1), receives a set of source code files associated with a specified project. In step 304, the computing system retrieves metrics data comprising software metrics associated with the source code files. In step 308, the computing system generates a set comprising the software metrics data. In step 310, the computing system generates (or calculates) based on the software metrics, first evaluation scores 1st (vi) associated with a source code file i. The first evaluation scores 1st (vi) may be generated by normalizing the value of an average of the software metrics by enabling the following equation 4:

In equation 4, K equals a number of software metrics, k equals a number of iterations enabled for retrieving the metrics data, x is a metric, v′i is the average of the metrics, and vi is a first evaluation score.


In step 318, the computing system generates a first graph displaying the first evaluation scores (e.g., see graph 202a in FIG. 2) and presents the first graph to a user. In step 320, the computing system receives from the user in response to presenting the first graph, a selection of a first source code file of the source code files. In step 324, the computing system calculates (i.e., based on the first source code file) parameter values associated with an evaluation function used to calculate second evaluation scores associated with the source code files. An objective function for calculating values for parameters a1, . . . , aK comprises the following objective function (i.e., equation 2 as described with respect to FIG. 2):

The objective function comprises a linear objective function and a set of linear inequality constraints. The linear objective function is configured to be solved by a linear programming technique as follows:


The objective of the linear objective function is to find the value of parameters a1, . . . , aK of equation 1 as described with respect to FIG. 2. Given software metrics xi0,1, . . . , xi0,K from the (first) reference source code file i0, the objective function is: aixi0,1+ . . . +aKxi0,K. Maximizing the objective function: aixi0,1+ . . . +aKxi0,K determines that the evaluation score vi0 of the reference source code file i0 is maximized under the following constraints:


There are I+K constraints so that the evaluation scores of all source code files are between zero and 1 as follows:


a1x1,1+ . . . +aKx1,K≦1−b,


a1x2,1+ . . . +aKx2,K≦1−b,


. . .


a1xI,1+ . . . +aKxI,K≦1−b,


a1≧0,


a2≧0,


. . .


aK≧0.


b is a constant value where 0≦b<1 holds. Finding values of parameters a1, . . . , aK so that the objective function: a1xi0,1+ . . . +aKxi0,K is maximized under the aforementioned constraints is solved by a linear programming technique.


In step 328, the computing system calculates second evaluation scores by enabling an evaluation function (i.e., equation 1 as described with respect to FIG. 2) using the parameter values. The evaluation function comprises:
