What is the difference between grey box testing and black box testing?

Hi Mark,

Here are some differences between the grey box and black box testing.

  • In grey box testing, QA partially knows the internal structure, design, and interaction in the software application. On the other hand, in black box testing, testers don’t have knowledge about the application’s internal structure, design, components, and interaction.

  • Grey box testing requires basic programming skills, whereas black box testing does not require high-level programming skills.

  • Grey box testing involves four testing techniques: Matrix, Regression, Orthogonal Array, and Pattern Testing. Black box testing involves six testing techniques: Equivalence Class Partitioning, Boundary Value Analysis, Decision Table, State Transitioning, Use Case Testing, and Cause-Effective Graph/ Graph-Based Technique.
