The present disclosure relates to a method and a system for generating a test suite comprising test cases. In one embodiment, the method generates the test cases based on functional requirements, service requirements and performance requirements received from a user such as a quality engineer associated with a software product or application. The method analyzes the interdependencies among the received requirements, generates sequences of the requirements based on the interdependencies and generates intermediate test cases based on the sequences. Further, the method deploys a test modeling tool on the intermediate test cases to generate final test cases which are then tested to evaluate the performance of the software product or the application. The test suite comprising the final test cases thus generated is rigid and provides a new dimension to the quality engineer to avoid the production failures and defect slippages and sustain the quality assurance (QA) of the business.
