Best Sample Test Cases for Library Management System

In this article, we’ll look into how to write test cases for Library Management System. It is one of the common manual testing interview questions that usually catches the candidate off guard.

A library management system has multiple functions and features, we have to make sure that we provide proper coverage to the library management system.

We can discuss test cases for library management systems in this article, here we use a generic library application to explain the test cases for library management systems.

As software testing process is a critical step that is involved in the overall development of any application. Library management systems are interesting projects that one can work on and implement in the real-time world.

Let’s look into the basic requirements for the library management system:

• Ensure that End users can register and log in.
• Ensure that the end user can search for the added books and check in or out.
• Ensure that the end user can pay the fine or extend the duration of the borrowed period.
• Ensure that the end user can change the password and other profile details.
• Ensure that the end user can add books.
• Ensure that the end user can place the holds and modify existing holds.
• Ensure that the admin user can manage the inventory of the books.

The above-mentioned features are some of the common functionality expected from any library management system. Hence you have a baseline for the list of things in the system you need to check for which in turn provides us with a starting point to write test cases for the library management system. In addition to these test scenarios, you should also check the graphical user interface (GUI) of the application to check for bugs, usability, and functionality.

Login test cases for the library management system

• Verify whether the username field accepts a valid username and if the password field accepts a valid password.
• Verify whether the wrong username and valid password allow access to any specific account.
• Verify whether the valid username and wrong password allow access to any specific account.
• Verify whether the forgotten username link leads to a username recovery page.
• Verify whether the forgot password link leads to the password recovery page.
• Verify whether the invalid username and password trigger any warning.
• Verify whether the invalid credentials open the random account.
• Verify whether the user is logged in, allows you to log out by using the link at the bottom of the application.
• Verify whether the logout link functions as expected.
• Book borrow/return interface test cases for the library management system
• Verify whether add, delete, update, search and exit button is seen.
• Verify whether the book gets added to the user’s borrow list when the user clicks on add button.

• Verify whether the new user is possible to add to the system using the member’s tab.
• Verify whether the password can be presented in this tab.
• Verify whether the user can be removed using the delete member feature.

Search functionality test cases for library management system

Search functionality is one of the crucial features of a library management system. It should allow the user to search for either other member profiles or books. There should be tabs that act as filters to let you choose between the user and the book. 

Verify whether the search function allows the user for search books as per title, ISBN, author, genre, or all of the criteria.

• Verify whether the profile search has the results listed as a table with profile information containing member info.
• Verify whether the right spelling of the book/author is displayed when the user enters the book/author’s name with a spelling mistake.

Resources inventory test cases for library management system

Every library has a resources system where the user can either search for the books available or can add or remove the books in the system. This module will have resources like books, magazines, courseware, CDs, or other resources.

• Verify whether you can add copy information for the resource.
• Verify whether you can add a category for the resource.
• Verify whether each field is for the limit of the text fields and also a valid input for the form.

Non-functional test cases for library management system

• Verify whether the system is reliable i.e. it should be available 24 x 7.
• Verify whether the system is accessible from any location which has an internet and it should be independent of the underlying devices i.e system should be responsive enough for mobile or tablet devices.
• Verify whether the user interface of the proposed system has an easy learning curve.
• Verify whether the user interface can guide the user for the next appropriate action during executing an operation.
• Verify whether the system can handle a huge number of transactions at a time.
• Verify whether the proposed system has a low throughput time to provide excellent performance.
• Verify whether the system has secure privacy for the users along with the confidentiality, integrity and availability of the data.

Basic functionality in the library management system

• Verify whether all the books listed in the system are sorted in ascending order
• Verify the functionality of the login field works as expected

Conclusion

The above scenarios might have given an idea of writing test cases for a library management system. You can expand it by creating more test cases for each input field, link and button. More possibilities can be derived from that, if you read the above cases they are the most common test scenarios which you can use.

When the question ” Write test scenarios for library management system” is asked by an examiner or interviewer without mentioning the specifics, you can use this article as a guideline for writing test cases for a generic library management system.
