To test for implicit requirements, a tester must become an expert in the customers problem domain and in the technology the software uses to solve those problems. Basically its a documentation on which test cases are based, such as requirements, design specifications, product risk analysis, architecture and interfaces. Understand the basic concept of functional and nonfunctional requirements in object oriented software engineering along with a case study and some small examples. Requirements analysis involves all the tasks that are conducted to identify the needs of different stakeholders. Equivalent partition in software testing boundary value. Requirements for test automation software quality methods. During the design phase, testers work to determine what aspects of a design are testable and with what parameters those tests work. It explains what is a business requirement, with requirements. In order to minimize the number of test cases required, design test cases to establish the presence of several related requirements.
