Abstract: Requirements engineering (RE) is employed to elicit, model, and analyse the requirements of software. Software requirements elicitation is the first sub-process of RE; and it is used to identify the requirements of software according to the need of the stakeholders. In literature, we identify that goal oriented requirements elicitation process (GOREP) do not support the identification of testing requirements from the functional requirements (FR) of software in early phase of RE. Therefore, to tackle this research issue, we proposed a method for the identification of the testing requirements from the FR in GOREP. In real life applications, only those requirements are implemented and tested, which are selected by the stakeholders. So in the proposed method we used fuzzy based technique for FR selection on the basis of non-functional requirements (NFR). The 'canonical representation of multiplication operation' (CRMO) associated with L⁻¹ R⁻¹ inverse arithmetic principle and 'graded mean integration representation' (GMIR) based on 'triangular fuzzy numbers' (TFNs) have been applied for the selection of the FR. In our work, an Institute Examination System (IES) is used as a case study to explain the steps of the proposed method.

Keywords: functional requirements; non-functional requirements; NFR; testing requirements; test cases; fuzzy based approach; triangular fuzzy numbers; TFNs.
