Web applications are a standard part of our everyday lives. Their purpose can vary significantly, from e-banking to social networks. However, one thing is similar – users have generally high expectations from different web applications. To assure such high expectations, proper web application testing is necessary. Non-functional testing is an important part of web application testing. As technology advances and requirements become more complex, the importance of non-functional application aspects becomes even greater. It is necessary to identify non-functional requirements of web applications which are important to users, implement those requirements and test them.
The availability of real-time data on the state of railway facilities and the state-of-the art technologies for data collection and analysis allow transition to the fourth generation maintenance. It is based on the prediction of the facility functional safety and dependability and the risk-oriented facility management. The article describes an approach to assessing the risks of hazardous facility failures using the latest digital data processing methods. The implementation of this approach will help set maintenance objectives and contribute to the efficient use of resources and the reduction of railway facility managers’ expenditures.
