FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -One level of maintenance testing is the in-service inspection or inspection, which typically is a test or series of tests performed on a frequency established by the manufacturer based on prior experience with the system/equipment/component or upon engineering analysis of the probable failure rate for the equipment.

Detailed explanation-2: -Unit Testing is a kind of white box testing, whereas Integration Testing is a kind of black-box testing. For Unit Testing, accessibility of code is required, as it tests the written code, while for Integration Testing, access to code is not required, since it tests the interactions and interfaces between modules.

Detailed explanation-3: -There are four main stages of testing that need to be completed before a program can be cleared for use: unit testing, integration testing, system testing, and acceptance testing.

Detailed explanation-4: -Integration testing focuses on ensuring various components within a program or system can function together well. Acceptance testing focuses on the client’s use of the system and how it functions as a whole unit, rather than on the specific interaction between different aspects.
