Our approach is based on model and it considers the business criticality value of the function.…”

Abstract-Software maintenance is an important and costly activity of the software development lifecycle. Regression testing is the process of validating modifications introduced in a system during software maintenance. It is very inefficient to re-execute every test case in regression testing for small changes. This issue of retesting of software systems can be handled using a good test case prioritization technique. A prioritization technique schedules the test cases for execution so that the test cases with higher priority executed before lower priority. The objective of test case prioritization is to detect fault as early as possible. Early fault detection can provide a faster feedback generating a scope for debuggers to carry out their task at an early stage. Model Based Prioritization has an edge over Code Based Prioritization techniques. The issue of dynamic changes that occur during the maintenance phase of software development can only be addressed by maintaining statistical data for system models, change models and fault models. In this paper we present a novel approach for test case prioritization by evaluating the Business Criticality Value (BCV) of the various functions present in the software using the statistical data. Then according to the business criticality value of various functions present in the change and fault model we prioritize the test cases are prioritized.

“…Korel et al [13,14] Korel et al [7] presented a comparison between codebased and model-based test case prioritization. The results from the experimental study indicate that model-based test prioritization detects early fault as compare to code-based test prioritization.…”

“…B. Korel et.al. [9] proposed a new prioritization technique to prioritize the test cases by using several model-based test case prioritization heuristics. Model-based test prioritization methods use the information about the system model and its behaviour to prioritize the test suite for system retesting.…”

“…One type of model-based test prioritization methods [7,8] are appropriate for modifications that involve changes in the model and then in the source code. The second type of model-based test prioritization methods [9] are appropriate for modifications that do not involve any changes in models (changes are only made in the source code). In this paper, we have used UML 2.0 for modelling to concentrate on the second type of model-based prioritization method.…”

Abstract-Software maintenance is an important and costly activity of the software development lifecycle. To ensure proper maintenance the software undergoes regression testing. It is very inefficient to re execute every test case in regression testing for small changes. Hence test case prioritization is a technique to schedule the test case in an order that maximizes some objective function. A variety of objective functions are applicable, one such function involves rate of fault detection -a measure of how quickly faults are detected within the testing process. Early fault detection can provide a faster feedback generating a scope for debuggers to carry out their task at an early stage. In this paper we propose a method to prioritize the test cases for testing component dependency in a Component Based Software Development (CBSD) environment using Greedy Approach. An Object Interaction Graph (OIG) is being generated from the UML sequence diagrams for interdependent components. The OIG is traversed to calculate the total number of inter component object interactions and intra component object interactions. Depending upon the number of interactions the objective function is calculated and the test cases are ordered accordingly. This technique is applied to components developed in Java for a software system and found to be very effective in early fault detection as compared to non-prioritize approach.
