Questions tagged [black-box-testing]

"Black box" testing tests a device, program, application, etc., as a whole. Inputs are provided and the results monitored. The internal workings of the tested item are not relevant and may be unknown. "Functional testing" is a type of "Black box testing", but not all "black box" tests have to be "functional".

Black box testing tests a device, program, application, etc., as a whole.

Inputs are provided and the output results monitored. The internal workings of the tested item are not relevant and may be unknown.

Black box testing and Functional testing are sometimes used synonymously, but Functional testing is really a subset. "Non functional" tests, like Stress testing are often done in a "black box" manner.

Compare and contrast to Unit testing and White box testing.

Can black box testing alone catch all errors that white box testing catches?

Is possible to find an error with white box testing that cannot be found with black box testing? If it is, then why? As I understand it, this is not possible, but I'd like to know for sure.

Which techniques for unit tests with poor functional requirements and no design specifications?

In my understanding, design specifications help to formulate unit test cases which make use of internal knowledge (white-box techniques), while if we only have functional requirements, the black-box techniques are more suited. What happens if we…
