To develop a test case for the Railway Reservation System (RRS), we will consider Black Box Testing as the testing technique, specifically Equivalence Partitioning and Boundary Value Analysis (BVA), since both are widely used for input domain-based testing in software engineering. These techniques help validate the system by checking functional outputs without knowing the internal code. ### Equivalence Partitioning for Railway Reservation System Equivalence partitioning divides input data into valid and invalid partitions and selects representative values from each partition to reduce the number of test cases while maintaining coverage. #### 1.
