Engineering Assignment Help – Selecting Test Cases

Development in engineering depends on measurement and test. We can select a set of test cases for any engineering products and process that can test products and process.

The following given program based on its specification. Consider the following informal specification for the Classification of triangle process Program. The program reads three input integer values from the standard input. The three input values are interpreted as representing the lengths of the sides of a given triangle. The program then after processing prints a message to the standard output that states whether the triangle, if it can be formed, is scalene, or isosceles, equilateral, or right-angled.

The specification of the given triangle classification program lists a number of inputs for the program as well as the form of output. Further, we require that each of the inputs should be a positive integer. Now, we can determine on next level valid and invalid equivalence classes for the input conditions.

Here, we may have a range of values. If the three input integers we have called x, y and z are all greater than zero, then, they are valid and we have the equivalence class.

Note that we could easily combine the valid equivalence classes. But, we are not allowed to combine the invalid group of equivalence classes. The output message consists of the text ‘strings’ ‘isosceles’, ‘scalene’, ‘equilateral’ and ‘right-angled’. Now, these different values in the input domain map to different elements of the output result to get the equivalence classes. According to the equivalence partitioning process and method we only need to choose one element from each of the classes above in order to test the triangle program.

Engineering Assignment Help could be very useful for student of all most all branches of Engineering and technology. Engineering assignment help provide time bound solution to complex problem of assignments.
