Nowadays ensuring high-quality software product requires a lot of testing efforts. Automated tests in the 21st century are a must. Whether it’s code peer-review, unit, integration, system or exploratory user testing – it all has to be done with given insurance and expertise! Therefore, we look to automate our testing where is conceivable. Most applications today have the equivalent of Web and Mobile versions for the same functionality, but different platforms of action in order to facilitate the users. Therefore, parallel testing of both subtypes is required to provide smooth maintenance and rapidity. Running as many builds as possible, including tests to ensure quality is essential when comes up to reliable software product and agile development. With the implementation of Continuous Integration and Continuous Delivery tools, we guarantee a better way to deploy automated tests across multiple instances and execute them against those environments. BrowserStack is one common cloud solution to these requirements. It is a very powerful tool, which can be attached to our development process. This article explores detailed approach on the automation of cross-browser, device and compatibility testing in BrowserStack platform, using a custom extended automation framework to provide direct configuration output to this environment and give ease in the future Web and Mobile development.

This article discusses the features of automation of discrete manufacturing processes. The peculiarities of application of industrial robots are analyzed. Emethod proposed for the study of roll-over systems, which allows the choice of the optimal solution under specific conditions

All production processes in the world are implementing Industry 4.0 by using the basic technologies such as robotics & automation, intelligent sensors, 3D printers, radio frequency identification – RFID, cloud computing, Internet of Things and Internet of Services. Implementation of Industry 4.0 in all production processes is not possible without the use of both industrial and service robots, their development and implementation. In addition, there are other technologies on which the fourth industrial revolution is based that will provide us with intelligent devices, intelligent production processes, intelligent logistics in production processes, i.e. intelligent factories. The Cyber-Physical Systems (CPS) in the global environment provide machine networking in production processes and logistics systems. This paper provides an example of the use of service robots and their role in solving smart transport in production processes.

In the paper is described a new computerized test bench for strength testing of roll over protective structures (ROPS) in tractor cabs. The static test procedure complies with international labor safety standards accepted in the Republic of Belarus.

Over the last two decades, software testing has expanded in terms of both the tools used to perform different types of activities and mind-set of the people using those tools. Automated testing involves use of strategies and instruments that perform testing activities of a software product and where the interference of a person is mainly related to the research of the results of these activities. Automated testing processes are popular because of the benefits that make them an indispensable tool in everyday work for testing activities. The main advantage of automation is the abstraction of rehearsal processes within the tested system. In this way, a complete separation of the human operations from the system is achieved, as only the functionality that needs to be programmed. This article presents the development of an automation-based testing framework “Stassy” – System Stable Testing, which supports and helps to implement easily new tests related to Web platforms. The implementation includes the following structure: Object repository, Functional libraries, Global variables and Constants, Data Provider, Test scripts, Configuration files, Recovery scenarios, Loggers, Clean-up scripts and Reporting mechanism. With the advantages of Page Object Pattern and using of the following technologies: Java programming language, JUnit and TestNG extended libraries. The created scripts represent automated acceptance, functional and non-functional tests in which Page Object is used to separate those tests into individual fragments and subsequently call them in a different order according to the automation requirements and business logic. We will track the overall preparation and creation of “Stassy” automated framework and explain the benefits of such approach.

Prevention 4.0 as part of the enterprise’s safety culture is developing HSE management system to address new challenges in prevention. Industry 4.0 anticipates new linkages between technology, man, and management systems to apply the most efficient IT systems to ensure the flexibility of the production process so that its output is a product that takes into consideration customer requirements. These changes include the existence of new types of risk due to the change of the position of man from the classical production centers to the area of superstructure activities, programmer, setter, maintainer, security technician for the digitization of production processes. Risk identification is based on defining the hazards and threats of a complex manufacturing system in the context of Safety and Security – Sa&Se, their formulation so that characteristic parameters can be efficiently digitized within the manufacturing process.

Intelligent production is the future of industrial production. They are leading the way to a new industrial era and best define the concept of the Fourth Industrial Revolution. And getting real-time data on quality, resources and costs provides significant advantages over classical production systems. Intelligent production must be built on sustainable and service-oriented technological and business practices. They are characterized by flexibility, adaptability and self-learning, resilience to failures, and risk management. The high levels of automation, on the other hand, become a mandatory standard for them, which is possible thanks to the flexible network of production-based systems that automatically monitor the production processes. Flexible systems and models that are capable of responding in real time allow internal processes to be radically optimized. Production benefits are not limited to one-off production conditions, and the capabilities include optimization through a global network of adaptive and self-regulating manufacturing components belonging to more than one operator.

Controlling of objects with the feedback negative loop is widely used in industry, intelligent technologies, robotics and transport systems. A negative feedback loop by comparing of the prescribed value of the output value with measured value of it generates a control signal, which adjusts the output value of the object. Typically, the number of controlled output values is equal to the number of feedback channels acting on the object, but in some cases, the number of the channel can be more. This situation is especially frequent in transportation systems. In the problem of the design of regulators, they pay the most attention to ensuring the required static and dynamic control accuracy, but recently the attention to the conservation of the resource manager increased. This saves fuel or energy costs, which is especially important, for example, in space technology. The task of saving resources in the control of an object with an excess amount of control channels was not previously considered in the literature. In this paper, the problem is investigated by numerical optimization with simulation. In some cases, the cost of resource of the control by the different channels may vary. At the same time the cheaper resources can have the worst quality of the control, for example, it can has a discrete form or (and) less speed and so on. In this paper, we study such state of the problem and give its solution. It is shown that for a suitable choice of the cost function one can preserve rather high quality of the control, while ensuring saving of the controlling resources. Resource saving can reach in some cases 96%, which is illustrated by an example.
