Which one of the following is true of software development models?
A. In Agile development models, the number of test levels for an iteration can vary depending on the project B. There must be at least four test levels for any software development model C. There are always four test levels in the V-model D. In a Rapid Application Development (RAD) project, there are four test levels for each iteration.
Explanation: In agile development model developers write every test case they can think of and automate them. Every time a change is made in the code it is component tested and then integrated with the existing code, which is then fully integration-tested using the full set of test cases.
