The testing effort required to test a software product depends on various factors, such as the size and complexity of the product, the quality of the requirements and design documents, the testability of the product, the test strategy and scope, the test environment and tools, the skills and experience of the testers, and the quality expectations and standards of the stakeholders1. Among these factors, the requirements for reliability and security in the product will most affect the testing effort required to test a software product1. Reliability and security are quality attributes that measure how well a software product performs its intended functions under specified conditions and protects itself from unauthorized access or harm1. Testing for reliability and security requires more rigorous and thorough testing techniques, such as reliability testing, security testing, penetration testing, stress testing, etc1. These techniques may require more time, resources, tools, and skills to perform effectively1. Therefore, the requirements for reliability and security in the product will most affect the testing effort required to test a software product.
