Real-time examples of black box testing include user acceptance testing of a mobile app, where testers evaluate functionality without knowing the code. An example of white box testing is unit testing, where developers test individual functions or methods in the code to ensure they work as intended.

Component testing can be both black box and white box testing, depending on the approach taken. When testers focus on the functionality of a component without examining the internal code, it's considered black box testing. If they analyze the code structure and logic, it's classified as white box testing.

Black box testing in manual testing involves evaluating a software application's functionality based solely on its specifications and requirements, without any knowledge of the internal code. Testers create test cases based on expected outcomes, focusing on inputs and outputs to ensure the software behaves as intended from the user's perspective.

Black box testing in software testing is a method where the tester evaluates the functionality of an application without any knowledge of its internal code or structure. The focus is on inputs and outputs, assessing whether the software behaves as expected according to its requirements. This type of testing is crucial for validating user requirements and ensuring that the application meets its intended purpose. Testers create test cases based on specifications and user scenarios, making it an essential part of the software development lifecycle.

No, black box testing and white box testing are not the same as User Acceptance Testing (UAT). 

- Black Box Testing: Focuses on testing the functionality of the software without knowledge of the internal code. It evaluates whether the software meets specified requirements.

- White Box Testing: Involves testing the internal structures or workings of an application. Testers have knowledge of the code and focus on code coverage, logic paths, and data flow.

- User Acceptance Testing (UAT): A specific type of black box testing conducted by end-users to ensure the software meets their needs and is ready for deployment.

So, while UAT can be considered a form of black box testing, it is distinct in its purpose and execution.

According to QA specialists, neither white box testing nor black box testing is universally better; each serves different purposes. White box testing is effective for identifying internal code issues, while black box testing is valuable for assessing user experience. A combination of both often yields the best results in quality assurance.

Issues in black box testing techniques include limited coverage of internal logic, making it difficult to identify hidden defects. Additionally, it may rely heavily on test cases, which can lead to incomplete testing if scenarios are not well-defined. There’s also a risk of overlooking system integration problems.
