In which testing technique the tester is aware of the internal workings of the product, has accer and in conducted to ensure that all internal operations are performed as per the specifications?

Correct Answer: Option 2) White box testing

Key PointsWhite Box Testing, also known as clear box, structural, or glass box testing, is a testing method in which the tester is aware of the internal logic of the system’s code. The main objective is to verify the internal workings and flow of the program.

• Tester knowledge: Complete knowledge of the internal structure and code.
• Access: Full access to the source code.
• Focus: Verifying internal operations like logic, loops, branches, and conditions.
• Example Techniques: Code coverage, path testing, loop testing, branch testing

Why Other Options Are Incorrect:

• Option 1) Integration Testing: Focuses on combining and testing multiple modules together. It checks the interaction between them but doesn’t necessarily involve knowledge of internal logic.
• Option 3) Acceptance Testing: A type of black-box testing done by end-users to verify if the product meets business requirements. Internal workings are not known.
• Option 4) Black Box Testing: The tester is unaware of internal code. Testing is based on input and expected output.

Additional Information

• White box testing is mainly performed by developers or testers with programming knowledge.
• It is used during unit testing or integration testing phases to ensure logic correctness.
• It helps find hidden errors that are not detectable through UI or functional tests.
