Black-Box Testing
Testing an application purely through its external behavior, without any knowledge of its internal code or implementation.

What is Black-Box Testing?
Black-box testing treats the software as an opaque box: the tester provides inputs and checks outputs against expectations, never looking at the source code. This mirrors how real users experience the product and keeps tests focused on behavior rather than implementation detail, which makes them resilient to internal refactors. End-to-end and acceptance tests are inherently black-box. Recording user flows into automated tests is a black-box approach by nature—you capture what a user does and assert on what they see, independent of how the feature is built underneath.
