Answer:
d.) black-box testing
Explanation:
Software testing can be regarded as procedures/process engage in the verification of a system, it helps in detection of failure in the software, then after knowing the defect , then it can be corrected. Black Box Testing can be regarded as a type of software testing method whereby internal structure as well as design of the item under test is not known by one testing it. In this testing internal structure of code/ program is unknown when testing the software, it is very useful in checking functionality of a particular application. Some of the black box testing techniques commonly used are; Equivalence Partitioning, Cause effect graphing as well as Boundary value analysis. It should be noted that the purpose of black-box testing is to isolate the behavior of a given component of software.
Answer: Both Agile and waterfall model are software development models to deliver a final outcome in the form of a software product. Waterfall model is sequential process with the requirements beings rigid and defined before beginning the software development.
Agile method basically concerned with the requirements of the client. Here both testing and development is carried out at the same time.
Explanation:
More differences between the two include :
Waterfall model is easy to manage whereas in agile model as the the client requirements changes and wants more functionalities is becomes a bit more difficult to manage. the role of project manager is very crucial in waterfall model whereas the role of developers ans testers is more important in Agile model.
Power is force multiplied by velocity. The engine power is actually (relatively) constant regardless of the gear. So when people say there is "more power" in a lower gear, it's the common misconception that "more powerful" is "more forceful" but that's only part of the equation.
So if P is constant, then that means if you can combine a large force and a low velocity or a low force and large velocity for the same power.
When you put it in a low gear, you produce a large torque -- or a large force -- and a low velocity.
For example, if you are towing a trailer or trying to climb a very steep grade, you need the force to be large which is why you put it in a low gear. If you are on something slippery like snow or ice, a high gear will keep the force at the wheels low so the tires don't exceed the coefficient of friction and spin.
