The testing time and cost of developed software can be reduced by automation of the whole or part of testing process. Since the testing automation tools to be used currently have been developed without their interoperability, test case information such as test procedures, test data, and expectation of test results generated at the stage of test execution cannot be shared and reused in other testing automation tools, In order to reduce testing time and cost, in this thesis, we have proposed a software testing automation framework which makes it possible to share and reuse the test case information generated in testing process. To prove the availability and effectiveness of proposed testing automation framework, three testing automation tools that are available in current market were experimented by the test scenario. As a result of experiment, the testing time and cost could be reduced by sharing and reusing the test case information in software testing automation framework.

This study attempts to derive critical success factors and prioritize activities for implementing the automation of software test. Software testing proceeds in five steps of test plan, test case design, test scripting & test environment setup, test execution & evaluation, and test closure. From the literature, twenty influence factors in the five steps were identified. Focus Group Interviews with ten experts in software testing selected fourteen factors on the basis of importance and feasibility. Some factors were further divided to clarify their meanings and the number of influence factors finally became twenty one. A survey on the influence factors was conducted with 75 IT professionals. An importance-feasibility analysis was applied to the survey responses and classified the influence factors into four groups of essential factors, critical factors, low priority factors, and minimal factors. Essential factors include objectives for test automation, strategies for test automation, test automation training, test automation education, setting up test automation environment, setting up test environment, test automation tool selection. Critical factors include management's continued support, management's continued interest, role of automation engineers, and skills of automation engineers. This result suggests that a lot of efforts should be put into SW test plan for the successful SW test automation and SW automation should proceed in consideration with the priorities and resource consumption.

Increased use of software and complexity of software functions, as well as shortened software quality evaluation periods, have increased the importance and necessity for automation of software testing. Automating software testing by using machine learning not only minimizes errors in manual testing, but also allows a speedier evaluation. Research on machine learning in automated software testing has so far focused on solving special problems with algorithms, leading to difficulties for the software developers and testers, in applying machine learning to software testing automation. This paper, proposes a new machine learning framework for software testing automation through related studies. To maximize the performance of software testing, we analyzed and categorized the machine learning algorithms applicable to each software test phase, including the diverse data that can be used in the algorithms. We believe that our framework allows software developers or testers to choose a machine learning algorithm suitable for their purpose.

Due to the rapid development of digital technnology and informantion communication, in the IEC 61850 based substation automation system, the innovative paradigm shift is expected and also required in many substation-related jobs, especially in the device function test area Accordingly a common testing model which can simplify the complex contents of the SAS performance test performed by test engineers has been identified, that can overcome limitations of engineers' own testing knowledge and experience. Testing models and its design system for the comprehensive performance test of the Substation Automation System is developed and the result of the study is reported in this paper.

Korea Electric Power Research Institute has carried out verification of communication conformance on IEC 61850 based IEDs related to power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology". Owing to IEC 61850 international standard and digital substation automation system, IED testing process should be changed from the conventional way to the new way described in the paper. This paper describes IED testing procedures based on substation automation system using UML.

Korea Electric Power Research Institute in charge of the power IT project "Development of Prototype for Advanced Substation Automation System based on the Digital Control Technology" is performing system verification. Breaker Failure protection IED can operate protection activity by communicating with other IEDs such as T/L IED, owing to IEC 61850 international standard and digital substation automation system. Accordingly, IED testing process should be changed from the conventional way by electrical contact test on individual IED to system based testing method by network communication. This paper describes how to test BF IED based on substation automation system and testing procedures using UML, which is used to implement S/W design.

Robot software components can be categorized into two types; the pure S/W component and the H/W-related one. Since interface testing of the robot software component is the labour-intensive and complicated work, an effective automated testing tool is necessary. Especially it is difficult to test all types of H/W-related components because it is hard work to prepare all H/W modules related to them. This paper proposes a new simulation-based interface testing automation tool(SITAT) which generates automatically test cases for interface testing of the robot software component and executes the interface test with the generated test cases where the simulator is used for simulation of the activity of a H/W module instead of the real H/W module. This paper verifies the effectiveness of the suggested SITAT with testing of the real H/W-related robot software component.

Heatcycle testing for aluminum connector is very important. But because of connecting or disconnecting the test circuit, measuring resistance is difficult. Also the previous measuring resistance instrument is analog type. So measuring method is difficult. And four measuring points for one test circuit cause difficulty in automation. In this paper we developed the automatic system for measuring resistance. Automation will allow more information to be gathered, which will lead to the connector aging process being better understood and controlled.

We have developed the testing software for KEPCO operators to maintain the small-scale distribution automation system effectively. The testing software is used to monitor the present status, to measure the analog value(voltage, amperage) and to control the switch and FRTU(Feeder Remote Terminal Unit) in order to find out a disabled part of the system. And at the stage of inspection of the switch and FRTU, it can screen the inferior one.

Agile development is mentioned a lot by developers these days. XP or Scrum is one of the popular development processes, and it says that unit test automation would drive an agile development successful. The success of unit test automation depends on how well to compare an execution result to its own expected result. that is why this paper focuses on the comparison part. This paper introduces how to build test codes for unit testing, and then concludes with mentioning two considerations of unit testing automation. First, test codes for void-typed methods need Mock Framework to monitor their behavior. Second, the comparison of execution results and expected results is hard to implement in case of testing void-typed methods. We check every sentences of a test path to decide if the testing is fail or pass.
