you are asked to test the log10 function (double log10(double a)) in Java Math library. You do not have the source code for the function however the specifications of the function are available. The specifications of the function as follows:Function returns the base 10 logarithm of the given double value.If the argument is equal to 10n for integer n, then the result is n.If the argument is NaN or less than zero, then the result is NaN.If the argument is positive infinity, then the result is positive infinity.If the argument is positive zero or negative zero, then the result is negative infinity.*NaN is a numeric data type value which stands for “not a number” (e.g. Double.NaN) 1. Explain why performing exhaustive testing (testing with all possible inputs) on this method might not be considered efficient testing and propose an efficient testing strategy.2. Explain how the proposed testing strategy is performed and list the minimum amount of test inputs required to perform it.

Question

you are asked to test the log10 function (double log10(double a)) in Java Math library. You do not have the source code for the function however the specifications of the function are available. The specifications of the function as follows:

Function returns the base 10 logarithm of the given double value.
If the argument is equal to 10ⁿ for integer n, then the result is n.
If the argument is NaN or less than zero, then the result is NaN.
If the argument is positive infinity, then the result is positive infinity.
If the argument is positive zero or negative zero, then the result is negative infinity.

*NaN is a numeric data type value which stands for “not a number” (e.g. Double.NaN)

1. Explain why performing exhaustive testing (testing with all possible inputs) on this method might not be considered efficient testing and propose an efficient testing strategy.

2. Explain how the proposed testing strategy is performed and list the minimum amount of test inputs required to perform it.
