The Buleleng Regency's Office of Trade and Industry has one of the tasks to develop and empower Small and Medium Industries (IKM) in Buleleng. One of the ways undertaken by the agency is to provide assistance to Bimtek entrepreneurship training or Technical Guidance. Bimtek is technical guidance assistance from government programs to improving and developing small and medium industries. However, sometimes this assistance is inconsistent because decisions are often changed. For this reason a decision support system was developed using AHP and SAW methods with 8 criterias including: number of monthly production, average product prices, number of equipment owned, number of employees, length of business establishment, annual sales value, total annual raw material and distance to Buleleng Government Commerce and Industry Office. The system developed can help the Buleleng Government Commerce and Industry to determine bimtek beneficiaries according to predetermined criterias. The development of this decision support system was built using the SDLC Method with a waterfall model. There are 4 tests performed including: blackbox testing, whitebox testing, accuracy testing, and user response testing. This study successfully developed a decision support system after passing the blackbox test and the whitebox test. Accuracy test showed very good results with an accuracy rate of 86.67%. The user response test conducted on 4 users including: admin, staff, IKM support and the general public has a mean percentage of 92.3% which is in a very good range.

Connections of cyber-physical system (CPS) components are gradually increasing owing to the introduction of the Industrial Internet of Things (IIoT). IIoT vulnerability analysis has become a major issue because complex skillful cyber-attacks on CPS systems exploit their zero-day vulnerabilities. However, current white box techniques for vulnerability analysis are difficult to use in real heterogeneous environments, where devices supplied by various manufacturers and diverse firmware versions are used. Therefore, we herein propose a novel protocol fuzzing test technique that can be applied in a heterogeneous environment. As seed configuration can significantly influence the test result in a black box test, we update the seed pool using test cases that travel different program paths compared to the seed. The input, output, and Delta times are used to determine if a new program area has been searched in the black box environment. We experimentally verified the effectiveness of the proposed.

A common problem in automated software testing is the need to generate many inputs with complex structure in a black-box fashion. For example, a library for manipulating red-black trees may require that inputs are themselves valid red-black trees, meaning anything invalid is not suitable for testing. As another example, in order to test code generation in a compiler, it is necessary to use input programs which are both syntactically valid and well-typed. Despite the importance of this problem, we observe that existing solutions are few in number and have severe drawbacks, including unreasonably slow performance and a lack of generality to testing different systems.This thesis presents a solution to this problem of black-box structured input generation. I observe that test inputs can be described as solutions to systems of logical constraints, and that more expressive constraints can lead to more complex tests. In order to test effectively and generate many tests, we need high-performance constraint solvers capable of finding many solutions to these constraints. I observe that constraint logic programming (CLP) offers an expressive constraint language paired with a high-performance constraint solver, and thus serves as a potential solution to this problem. Via a series of case studies, I have found that CLP (1) is applicable to testing a wide variety of systems; (2) can scale to more complex constraints than ever previously described; and (3) is often orders of magnitude faster than competing solutions. These case studies have also exposed dozens of bugs in high-profile software, including the Rust compiler and the Z3 SMT solver.

The types of the testing methods were analyzed from the side of development. If changes are made to the code, even minor ones, bugs can appear anywhere in the system. The cost of fixing bugs increases with the time they are discovered. Using effective web testing can prevent unexpected costs. Modern web applications are indeed a place where all the type of the testing is vital for the high-quality product. At the moment, traditional front and back office applications are increasingly moving from desktop computers to web interfaces, so testing web applications is becoming extremely relevant. Thus, learning what to automate and how is an important component of successful web application testing. Web application testing is a software practice that is designed to ensure quality by verifying that the functionality of a particular web application works correctly or according to fixed requirements. Web testing makes it possible to find bugs at any point in time, before release or on a daily basis. On the one hand there are wide range of tools that could be used to pursue this goal by means of using best decisions present for now but on the other hand there are essential advantages and disadvantages present in these tools, which are all in the approach to it, so there are always cons and pros of using one or another. For now, despite on having the ability to test using both black and white box testing it looks like the second one is not the best choice. There are several points on each board for both of them, but black box approach that is being represented with react testing library is more successful and efficient way to cover and application with high- and low-level tests, that could be easily maintained and understood. But white box testing is now the most used decision due to the historic development of the industry. So, it also has some great features and could be chosen to be used on the project, but it should be precise choice with the understanding of all the consequences standing behind. Види методів тестування були проаналізовані з боку розробки. Якщо в код вносяться зміни, навіть незначні, помилки можуть виникнути будь-де системі. Вартість виправлення помилок зростає з часом їх виявлення. Використання ефективного веб тестування може запобігти непередбаченим витратам. Сучасні веб застосування дійсно є місцем, де весь тип тестування є життєво важливим для якісного продукту. На даний момент традиційні фронт та бек-офісні програми все частіше переходять з настільних комп’ютерів на веб інтерфейси, тому тестування веб застосувань стає вкрай актуальним. Таким чином, вивчення того, що і як автоматизувати, є важливим компонентом успішного тестування веб застосувань. Тестування веб застосувань є практикою програмного забезпечення, яка призначена для забезпечення якості за рахунок перевірки того, що функціональні можливості певного веб програми працюють правильним чином або відповідно до зафіксованих вимог. Веб тестування дає можливість знаходити помилки в будь-який час, до релізу або щодня. З одного боку, є широкий спектр інструментів, які можна було б використовувати для досягнення цієї мети за допомогою використання найкращих рішень, присутніх на даний момент, але з іншого боку, є суттєві переваги і недоліки, присутні в цих інструментах, які всі в підході до нього, тому завжди є мінуси і плюси використання того чи іншого. Поки що, незважаючи на можливість тестування з використанням як чорної, так і білої скриньки, останній метод має багато недоліків та не рекомендується до використання. Ці два методи мають місце бути у окремих проєктах, але підхід чорної скриньки, який представлений бібліотекою тестування React є найбільш успішним і ефективним способом покрити і застосування з високими і низькими тестами, які можна легко підтримувати і розуміти. Але тестування білої скриньки в даний час є найбільш вживаним рішенням у зв’язку з історичним розвитком галузі. Отже, воно також має деякі позитивні риси і може бути обрано, щоб бути використаним на проєкті, але повинно бути точним вибором з розумінням всіх наслідків, що за ним слідують.

AI algorithms promise solutions for situations where conventional, rule-based algorithms reach their limits. They perform in complex problems yet unknown at design time, and highly efficient functions can be implemented without having to develop a precise algorithm for the problem at hand. Well-tried applications show the AI���s ability to learn from new data, extrapolate on unseen data, and adapt to a changing environment ��� a situation encountered in fl ight operations. In aviation, however, certifi cation regulations impede the implementation of non-deterministic or probabilistic algorithms that adapt their behaviour with increasing experience. Regulatory initiatives aim at defining new development standards in a bottom-up approach, where the suitability and the integrity of the training data shall be addressed during the development process, increasing trustworthiness in eff ect. Methods to establish explainability and traceability of decisions made by AI algorithms are still under development, intending to reach the required level of trustworthiness. This paper outlines an approach to an independent, anthropomorphic software assurance for AI/ML systems as an additional layer of trustworthiness, encompassing top-down black-box testing while relying on a well-established regulatory framework.

In this essay, we explore a new pedagogical framing ofway of pedagogically and teaching the Liskov Substitution Principle (LSP). In addition to, or perhaps even in place of, teaching the specifics of the rule itself, we advocatepropose teaching an operationalised version of the rule: that a subtype must pass its supertype’s black box tests for each of its overriding methods. We leverage the fact that black box tests should be written to capture conformance to a specification without overfitting or checking implementation internalsdetails (as would be checked by glass box tests). A type that violates the rules of substitutability will also fail a potential corresponding black box test for the supertype. Additionally, we argue that the over-strict nature of the classical LSP Postcondition Rule (which has been improved in subsequent work) can be a source of confusion for both instructors and for students learning this crucial concept for the first time. Pleasingly, many of the technical subtleties of this nuanced but important concept drop out naturally when thinking of substitutability via black box tests. Thus we put forward We propose that this test-oriented means of teaching substitutability is a valuable alternative to the classical sense of checking the LSP, with the benefit of being intuitively accessible to students.

A denial‐of‐service (DoS) attack is a serious attack that targets web applications. According to Imperva, DoS attacks in the application layer comprise 60% of all the DoS attacks. Nowadays, attacks have grown into application‐ and business‐layer attacks, and vulnerability‐analysis tools are unable to detect business‐layer vulnerabilities (logic‐related vulnerabilities). This paper presents the business‐layer dynamic application security tester (BLDAST) as a dynamic, black‐box vulnerability‐analysis approach to identify the business‐logic vulnerabilities of a web application against DoS attacks. BLDAST evaluates the resiliency of web applications by detecting vulnerable business processes. The evaluation of six widely used web applications shows that BLDAST can detect the vulnerabilities with 100% accuracy. BLDAST detected 30 vulnerabilities in the selected web applications; more than half of the detected vulnerabilities were new and unknown. Furthermore, the precision of BLDAST for detecting the business processes is shown to be 94%, while the generated user navigation graph is improved by 62.8% because of the detection of similar web pages.

Context: In many domains, engineers build simulation models (e.g., Simulink) before developing code to simulate the behavior of complex systems (e.g., Cyber-Physical Systems). Those models are commonly heavy to simulate which makes it difficult to execute the entire test suite. Furthermore, it is often difficult to measure white-box coverage of test cases when employing such models. In addition, the historical data related to failures might not be available. Objective: The objective of the approach presented in this paper is to cost-effectively select test cases without making use of white-box coverage information or historical data related to fault detection. Method: We propose a cost-effective approach for test case selection that relies on black-box data related to inputs and outputs of the system. The approach defines in total six effectiveness measures and one cost measure followed by deriving in total 21 objective combinations and integrating them within Non-Dominated Sorting Genetic Algorithm-II (NSGA-II). The proposed six effectiveness metrics are specific to simulation models and are based on anti-patterns and similarity measures. Results: We empirically evaluated our approach with these 21 combinations using six case studies by employing mutation testing to assess the fault revealing capability. We compared our approach with Random Search (RS), two many-objective algorithm, as well as three white-box metrics. The results demonstrated that our approach managed to improve Random Search by up to around 28% in terms of the Hypervolume quality indicator. Similarly, black-box metrics-based test case selection also significantly outperformed those of white-box metrics. Conclusion: We demonstrate that test case selection is a non-trivial problem in the context of simulation models. We also show that the proposed effectiveness metrics performed significantly better than traditional white-box metrics. Thus, we show that black-box test selection approaches are appropriate to solve the test case selection problem within simulation models.

Given a drawing of a read-once formula (called the blueprint), and a blackbox implementation with the same topology as the blueprint that purports to compute the formula, can we tell if it does? Under a fault model, where the only faults in the implementation are gates that complement their outputs, we show that there is an efficient algorithm that makes a linear number of probes to the blackbox implementation and determines if the blueprint and implementation are identical. We also show a matching lower bound. We further ask whether we can diagnose where the faults are, using blackbox testing. We prove that if the implementation has a property called polynomial balance , then it is possible to do this efficiently. To complement this result, we show that even if the blueprint is polynomially balanced and there are only logarithmically many errors in the implementation, the implementation could be unbalanced and the diagnosis problem provably requires super-polynomially many tests. We point out that this problem is one instance of a general class of problems of learning deviations from a blueprint, which we call conformance learning . Conformance learning seems worthy of further investigation in a broader context.

STIS Polytechnic of Statistics (PS-STIS) is an institutional unit with high work complexity and density. In carrying out its personnel activities, there is no support system that can be used by employees to store and process knowledge related to their work. This may indirectly lead to ineffective and inefficient work in term of costs, time, and other resources. Job-related knowledge is stored in accordance with the decisions of each employee. When needed, knowledge acquisition becomes slow and knowledge is also prone to be scattered or even lost. In this study, we will discuss about design and development of knowledge management system within the scope of PS-STIS. The focus of this research is related to the integration of the system functions to be able to perform knowledge storage, collaboration, and retrieval. The web-based system built applies the basic principles of Knowledge Management System (KMS). it has pages and permissions in accordance with the interests and responsibilities of users. In this research, we used SDLC development method to build the system and evaluated it using blackbox testing method and Survey Usability Scale (SUS). Result of blackbox testing showed that all function performed like expected and SUS score of 74 showed that system built was acceptable to users.

Indonesia is predominantly Muslim country. However, around 54% of Muslims cannot read the Qur'an. Many teenagers and adults argue that this is due to lack of time, shame to learn, not having a teacher and so on. Based on these problems, many methods are formulated to help the community in learning. The Tsaqifa method is one method that is claimed to make people able to read the Qur'an in just 7.5 hours. However, along with technological advances, this method began to be considered conventional. Therefore, there needs to be a new alternative so that learning methods can keep up with technological advances. Utilization of instant messaging can be used as an alternatives to implement existing learning methods especially Tsaqifa method that is expected can help communities learn independently, quickly, easily and interactively. In this study, the application of the Tsaqifa method was carried out by developing an application of chatbot in learning the Al-Qur'an reading media that utilizes the LINE Messaging API. Applications that have been built are tested with 2 methods that is Blackbox Testing and System Usability Scale (SUS). In testing using Blackbox Testing, the overall functionality of the application has been declared successfully run and based on the results of the System Usability Scale (SUS) test, obtained an average score of 73.3 out of 20 respondents which means the application can be accepted by the public (acceptable).

The Bali Institute of Health Sciences (STIKES) is a higher education institution in the health sector. Education in an institution needs to be monitored especially the lecture process. At present, the process of monitoring lectures is carried out by recording into paper documents. Several problems arise, namely at the end of each semester staff who perform lecture attendance recapitulation must open a sheet per lecturer attendance form sheet. Then from the lecturer attendance form, the staff in charge must type back into the Microsoft Excel application. This resulted in 2 problems, namely the occurrence of delays in reporting and the difficulty of monitoring lectures by Puket I. From these problems a system is needed that is able to provide information on the presence of lecturers and is able to present information on lecture activities in realtime. The design of this system is translated through Data Flow Diagrams and built using PHP language, for display using CSS, and database using MySQL. Testing this system uses blackbox testing. The lecture monitoring information system can display information about the implementation of lectures for Chairperson I Assistant in real time and can facilitate STIKES Bali staff in conducting lecturers' attendance.
