Question 175 Explanation:
Statement-1:
→ Regression testing is re-running functional and non-functional tests to ensure that previously developed and tested software still performs after a change. If not, that would be called a regression.
→ Changes that may require regression testing include bug fixes, software enhancements, configuration changes, and even substitution of electronic components.
→ As regression test suites tend to grow with each found defect, test automation is frequently involved.
Statement-2: Black box testing methods are
1. Graph-Based Testing Methods
2. Equivalence Partitioning: It is a black box testing technique that divides the input domain of a program into classes of data from which test cases can be derived.
3. Boundary Value Analysis
4. Orthogonal Array Testing
