Language is an important tool for communicating with people. With the continuous development of Sino-Russian relations, the Russian language is becoming more and more significant in exchanges and communication between the two countries. In China, more and more universities offer the specialty "Russian language". As a necessary communication tool, it allows students to apply the acquired knowledge in real conversations and it is aimed at developing students' comprehensive listening, speaking, reading and writing skills, so linguodidactic testing plays an integral role. With the help of the test, the identification of students' shortcomings and their timely correction are of great importance for teaching students, monitoring and improving their level of knowledge of the Russian language. The relevance of the problem under study lies in the fact that a comprehensive and effective testing model is developed to control the knowledge gained by students within the framework of the quality indicators of linguodidactic testing, taking into account the ethnopsychological characteristics of Chinese students. The purpose of the article is to work out a testing model within the framework of the quality indicators of linguodidactic testing, taking into account the implementation of the ethnopsychological characteristics of Chinese candidates. Methods to study the problem are analytical, synthetic, comparative, descriptive and mathematical ones. The main results of the article are that reliability, validity and practicality, taking into account ethnopsychological characteristics, are closely related. In addition, reliability and validity complement each other, but there are also some contradictions. The test site and test model are determined by examining relationships that can be expressed in terms of triangles. The theoretical significance of the article is in the definition of reliability, validity and practicality in relation to psychological characteristics that are important in the preparation of RFL tests, and in the development of a testing model for RFL for Chinese students. The practical significance lies in planning and development of a test model for Russian as a foreign language for Chinese students, in the possibility of using this work for teachers of Russian as a foreign language.
