Debugging Techniques: Test Cases for Identifying and Fixing Bugs

This project involves debugging a Java-based hotel booking application by identifying, replicating, and correcting errors within the code. The debugging process utilizes techniques such as incremental testing, trace back testing, and sanity checks to pinpoint and rectify bugs. The project emphasizes the importance of generating test cases to reliably reproduce buggy behavior, simplifying tests for clarity, and tracing errors back to their origin through hypothesis and testing. NetBeans is used as the primary tool for implementing and testing the code, with the goal of achieving a fully functional and error-free hotel booking application. Desklib provides access to this assignment, offering valuable insights into debugging methodologies and practical application.

Introduction
This project checks, detects and corrects the bugs for the given code file. Debugging
is a part of the software testing process. It analyzes the data and corrects the code. It is an
integral part of software development lifecycle. The computer program contains lot of errors.
It tests the code and displays the error in the program. The error will be rectified by using the
software testing concept. Debugging’s main concept is to correct the error and display the
proper program with respective output. In this project, we check and detect the errors of the
java file and correct the entire code. It is a hotel booking based java code, where it is required
to check the error and display the proper code in the java file.
Debugging
Debugging means checking and detecting the error in the particular code. If you have
error in the code file then it corrects the error. It finds the errors and solves the problems. It is
one of the software testing problem (Grötker, 2012). It tests the code and displays the error.
The programmer makes the mistake in writing the program. The error is rectified by the
software testing developer. In this project, the java code provides the correct code. It is hotel
booking based java file, which has many mistakes in running the code. We run the file by
using the net beans.
Hotel Booking
In out project based on the hotel booking website using the java files. It contains
booking, checking, credit, entities and service. The credit file contains credit authorizer,
credit card and credit card type (Honarmand & Torrellas, 2014). The entities file contains the
booking, guest, hotel, room, room type, service charge and service type. We are checking the
error for this java file and detect the error. Finally we correct the error and display the output
of a proper code.
Debugging techniques
It is a debugging methods, whose types include incremental testing, trace back testing,
and sanity checks etc. The incremental testing works from the lower level to the higher level.
The code has several errors when using the incremental testing. The sanity checks to correct
the low level code. Its main advantage is detecting the error, early. The trace back technique
is used to detect the Boolean error.

Code error
In this project, the main file refers to booking. It is a package java file for all the files.
Import all the files depending on the main file. The booking file has the credit file, room file,
room type file, service charge file and service type file. Sometime when the code is run, it
will detect the error. The main java file has all the files. The main file has all the java package
file. The maim package file is hotel. In this file, all the sub files are present (MA, ZHOU,
ZHANG, LI & LI, 2012). The main error is detected and it affects the sub files. First, import
all the files depending on the hotel package file. Then, run the code to check the file and
detect the code file. Finally, it corrects the error code and it displays the output for the proper
code.
Testing and Debugging
Testing means it just shows the presence of error. Debugging corrects the bugs.
Testing means it tests the entire code and it displays the error of the code. It also checks and
detects the error. Debugging is one of the software testing. Debugging corrects the entire
error. In our project, the hotel booking java file has many mistakes. Every file is imported
step-by-step. We take the main hotel java. It has the importing file and imports all the files
such as, credit, room, booking, service charge, and service type and room charge. The file has
some import file. Every package file is a hotel booking file.
Software interface
Here, net beans is used for implementing the program. The java file can be run by the
net beans or eclipse. We run the java file in net beans. The hotel project is created and it
imports all the files to detect the error (Tracey, 2010). Next, the process of checking and
detecting the errors, using net beans is carried out and finally the complete code is corrected.
Conclusion
This project solves the error file. First, we check and detect the available errors. The
net beans is used for running the program. It detects all the errors. The given project file is a
java file. It is based on the hotel booking webpage. It has booking file, credit authorizer file,
card type, room file, room type file, guest file, service charge file and service type file. The
main file is hotel. Each file imports through the main file. Finally, correct the code and
display the proper code with appropriate output.
