Definition - What does Risk-Based Testing (RBT) mean?
Risk-based testing (RBT) is essentially a test performed for projects depending on the risks. Risk-based testing strategies make use of risks to prioritize and highlight the right tests at the time of test execution.
Considering that there might not be ample time to check all kinds of functionality, risk-based testing mainly concentrates on testing the functionality that carries the biggest impact and the possibility of failure.
Risk-based testing strategy organizes the testing tasks in such a way that it cuts down the remaining level of product risk at the time of system deployment.
Risk-based testing is done on a project at the very early stages. This helps identify the project risks that disclose the project quality. This information, in turn, leads to the testing of the planning, specifications, preparations and execution.
Risk-based testing involves both contingency and mitigation. It also features a measuring process, which identifies how well the organization is working at discovering and eradicating faults in crucial areas. Furthermore, it also employs risk analysis to identify proactive probabilities to avoid or remove defects via non-testing routines and to help the organization select the required test activities for execution.
The important processes involved in risk-based testing are as follows:
Identify every requirement with regard to the risks associated with the project.
When it comes to assessing risks, prioritize the needs.
Prepare and outline the tests based on requirement prioritization.
Perform the test as per prioritization as well as approval criteria.
Advantages of risk-based testing:
Enhanced quality -- All vital application functions are tested.
Involves clear, real-time comprehension of project risks. Concentrates mainly on business project risks rather than on the information system functionality.
Association of the product risks with requirements recognizes gaps.
In the course of testing, test reporting always occurs in a language easily understandable by all parties involved.
Always concentrates on the most crucial concerns first; efforts are not misused on low-risk or non-critical functions.
Customer participation, effective reporting and progress monitoring improve customer satisfaction.
