Black Box Testing

A search engine is a simple example of an application subject to routine black box testing. A search engine user enters text in a Web browser's search bar. The search engine then locates and retrieves related user data results (output).

Black box testing advantages include:

• Simplicity: Facilitates testing of high-level designs and complex applications
• Conserves resources: Testers focus on software functionality.
• Test cases: Focusing on software functionality to facilitate quick test case development.
• Provides flexibility: Specific programming knowledge is not required.

Black box testing also has certain disadvantages, as follows:

• Test case/script design and maintenance may be problematic because black box testing tools depend on known inputs.
• Graphical User Interface (GUI) interaction may damage test scripts.
• Testing only covers application functions.
