Final answer:
Maintenance testing methodologies include Breadth Test and Depth Test, Re-testing, Confirmation Testing, and Sanity Testing.
Step-by-step explanation:
Maintenance testing is an important part of software development. It involves various methodologies to ensure that the software remains functional and bug-free after updates or modifications. Some of the commonly adopted methodologies for maintenance testing include:
- Breadth Test and Depth Test: These are two types of testing that aim to cover a wide range of functionalities (breadth) and the deep aspects of a system (depth).
- Re-testing: This involves running tests on specific areas or functionalities that have been modified or fixed.
- Confirmation Testing: This is done to validate the fixes made in the software and ensure that they have resolved the reported issues.
- Sanity Testing: This is a quick and basic test to check if the software is stable enough for further testing.
