What is parameter, Software Engineering

Assignment Help:

In software QA or software testing, a parameter is an item of information - like a name, number, or selected option - that is approved to a program, by a user or another program. By definition, in software, a parameter is a value on which something else depends. Any desired numerical value might be given as a parameter. In software development, we use parameters when we want to permit a specified range of variables. We use parameters when we require differentiating behavior or passing input data to computer programs or their subprograms. Therefore, when we are testing, the parameters of the test can be varied to produce dissimilar results, because parameters do affect the operation of the program receiving them.
