Test Techniques Overview

Test techniques are systematic approaches used to design ana analyze tests to uncover deects or verify the conformance of a system or software product to its requirements.

Various techniques:

1. Black Box Testing

• Test system without knowledge of internal structure or implementation details.
• Equivalence partitioning, boundary value analysis, decision table testing, state transition testing, etc.

2. White Box Testing

Also known as structural testing, white box testing invovles testing the internal structure, design.

3. Experience-based test techniques

• Also known as heuristic or information techiques, relies on the tester’s knowledge, skills, and experience to identify potential defcts.
• Not formal specifications or predefined test cases, but it’s based on intution or gut feeling.
• Experience-based techniques rae highly flexible and can complement other formal techniques
• Relies on a tester’s domain and systems knowledge which makes their intuition an effecitive tool for identifying potential issues tool that could be missed by formal test cases or specs alone.
