Testing undoubtedly involves numerous types, methods, and ways of verifying the actual behavior of the system against the expected behavior. Among the fundamental types are black box and white box testing, which are worth getting to know more closely. What are these types, and what checks do they entail?
Black Box Testing is a software testing method in which the functional capabilities of the software are tested without knowledge of the internal code structure and implementation details of the system. Black Box Testing primarily focuses on the input and output information of the product and is entirely based on the requirements and specifications of the software. It is also known as external testing, closed testing, or behavioral testing.
The «black box» can be any resource, whether it's an operating system, website, application, or database. This type of testing does not require knowledge and information about the architecture or structure of the product, so the checks are essentially carried out on behalf of an ordinary user.
Some of the most well-known types of black box testing include functional testing, non-functional testing, and regression testing.
