Development of technical solutions and equipment cost reduction led to the expansion of digital tools to different fields of activities, computing has become ubiquitous due to formalization and rationalization of living processes. Cognitive activity is also transforming due to the introduction of computing, but it is necessary to measure the degree of digitalization of intelligent processes so that researchers and educators can better understand the practical results of digital learning. The effectiveness of digital learning tools has been evaluated over the past decade based on online courses. Testing is a learning element that easily turns knowledge assessment into routine operations. The study of knowledge creation demonstrates the complex role of networking and communication among students, which is built and structured in preparation for passing tests. Developing test content and design and improving test conditions can help improve learning by transferring and sharing knowledge between students. A survey conducted at the St. Petersburg Polytechnic University allowed researchers to formulate several technical, organizational and methodological recommendations for improving testing and draw conclusions about the social, cultural and intellectual impact of tests on learning outcomes.
