Risk-based testing (RBT) is a software testing technique that evaluates the probability of risk based on several factors such as edge-case scenarios, business impact, effort complexity, and dependencies,... RBT involves identifying those scenarios or test cases that fit into the above factors to determine the most critical or sensitive scenarios to be validated in times of crunch or shorter QA cycles. To summarize, risk-based testing involves testing the functionality which has the highest impact and probability of failure.
