Question

Within the Discussion Board area, write 3 paragraphs that respond to the following questions with your thoughts, ideas, and comments. This will be the foundation for future discussions by your classmates. Be substantive and clear, and use examples to reinforce your ideas:

Describe the importance of integration testing.

Provide example test cases that would be included in the integration test for your GUI application.

Describe 3 debugging techniques you could use if errors are found.

Answer 1

Debugging Techniques

To perform the debugging process easily and efficiently, it is necessary to follow some techniques. The most commonly used debugging strategies are,

Debugging by brute force

Induction strategy

Deduction strategy

Backtracking strategy and

Debugging by testing.

Debugging by brute force is the most commonly used technique. This is done by taking memory dumps of the program which contains a large amount of information with intermediate values and analyzing them, but analyzing the information and finding the bugs leads to a waste of time and effort.

Induction strategy includes the Location of relevant data, the Organization of data, the Devising hypothesis (provides possible causes of errors), and the Proving hypothesis.

Deduction strategy includes Identification of possible causes of bugs or hypothesis Elimination of possible causes using the information Refining of the hypothesis( analyzing one-by-one)

The backtracking strategy is used to locate errors in small programs. When an error occurs, the program is traced one step backward during the evaluation of values to find the cause of bug or error.

Debugging by testing is the conjunction with debugging by induction and debugging by deduction technique. The test cases used in debugging are different from the test cases used in the testing process.
