The paper describes developing methods of tests for the requirements checking that provide 100 % coverage of the initial specifications for the system by test cases. Proposed approach of criterion chains are used in the traceability matrix. The criteria chains are used to automatic generation of test scenarios. Also the article describes methods for generating scenarios and selection of scenarios that satisfy the selected integral coverage criteria. The use of suggested integrated tests criteria for the requirements checking at the stage of a formal specification of the system, allows to cover by test scenarios all the initial requirements of the system.
