Test Cases for Inventory Management System

How to Write Test Cases for an Inventory Management System

Inventory management systems are highly complex software applications that track the inventory of products within a supply chain. Each product is tracked and typically provides real-time updates on status and location. Data security is critical as is scalability and ensuring integrated apps, databases, and APIs work as expected. 

For example, a hospital may use inventory tracking to manage medications and supplies. Each time a medical provider uses a bandage or provides a prescription or OTC drug to a patient, the system updates the quality still on hand, which medical provider used the product, and whom it was provided and when. 

Most inventory management systems use barcoding or GPS tracking options to track inventory counts and movements. All movements are part of an audit trail to ensure compliance with various regulatory requirements. 

When creating test cases for an inventory management system, be sure to include tests for business analytics data and reporting for accuracy. 

The tests include the following:

• Usability

Customer experience is critical for applications in a highly competitive space like inventory management. 

Usability is a manual type of testing used to verify customer workflows work correctly for all application functions.

• Exploratory

Exploratory testing is handy for not only testing usability but all functionality manually to ensure workflows are logical and perform as expected. 

• Functional (Feature or Story)

Functional testing includes testing for new features or user stories during the SDLC (software development lifecycle). 

Tests are either automated or manual and created and executed during an Agile sprint. 

Tests verify the application meets all stated requirements and acceptance criteria.

• Data management

Data verification is best done with automated tests for improved accuracy. 

Ensures the data stored, transferred, and received is valid. 

• Security

Any application requires thorough security testing to ensure data security and compliance with standards for all countries where the provider does business. 

Most security and vulnerability tests are manual but may be automated for repeat execution. 

• API 

API tests are easily covered with automated tests that can be executed on a schedule to ensure APIs continue to function. 

Modern applications depend heavily on APIs to share and transfer data securely. 

• Integration

Integration testing provides assurance that all components and dependencies work together as expected. 

Critical to ensure the application works as expected for customers when all integrated applications, databases, and other dependencies are functional. 

• End-to-end (system)

Testers can leverage automation to execute end-to-end or system tests to ensure the application functions for all customer workflows. 

Automation is helpful to run end-to-end tests repeatedly during subsequent development cycles to identify any new defects. 

For more thorough test coverage, include both positive and negative tests. The best way to create negative tests is to reverse positive tests or execute steps out of order. Another option is to do exactly the opposite of what the application expects. The purpose is to identify defects when users don’t follow the expected workflow pattern.

In the next section, we’ll provide examples of tests to create for an inventory management system. 

Sample Test Cases for an Inventory Management System

Test cases for inventory management systems require thorough test cover meaning your test strategy must include the testing types previously mentioned. 

Test types to write inventory management test cases include:

• Usability

• Exploratory

• Functional (Feature, or Story)

• Data management

• API

• Integration

• End-to-end (system)

• Security

Security is typically performed by an external testing source. In this case, substitute security testing with load or performance testing. Performance and load testing can ensure the customer experiences a highly performant system and can get their work done productively. No one wants to wait endlessly for a process to complete. Better performance often translates into a more positive customer experience with an application. 

Sample test objectives to include in one of the test types above:

• Verify part numbers, serial numbers, and barcodes are unique per product. 

• Verify unique ID numbers are generated for each product. 

• Configure product categories and subcategories and map items to both. 

• Set the bay, bin, or bucket settings for a variety of products. 

Negative test suggestion: Set one or more products to the same bay, bin, or bucket. Users should get an error as each should have to be unique. 

• Set item reorder levels that trigger inventory replacement. 

Negative test suggestion: Leave a reorder level blank or null so the product is not reordered. Users should get an error or warning to set a reorder level value. 

• Configure a base price and depreciation settings for products. 

• Set up a lot number allocation for bulk storage products. 

• Add stock adjustment notes to one or more products. 

• Move, ship, or use inventory products within the same physical location. 

• Move, ship, or use inventory products between different locations. 

• Execute inventory management counts and verify count data. 

• Export inventory data or batch data to a central warehouse or control center.

• Import inventory data or batch data from a central warehouse. 

Negative test suggestion: Use an invalid count number or invalid characters that are numeric. 

• Run reports for the day, week, or month and review item quantities. 

• Search for products that are in stock and ones that are out of stock. 

• Move, use, or ship a product in inventory. Reverse or cancel the process. 

Negative test suggestion: Allocate a product to a bin or storage location that is not valid. 

• Alter the price of a product right after a transfer.

• View product storage layouts in a graphical or visual mode. 

• Edit a product to require special storage bins with freezing temperatures. 

• Upload new product images using valid formats and sizing. 

Negative test suggestion: Upload an image using an invalid format or where the size is too large. 

• Approve a product return and verify inventory count.

The above test cases are a sampling of what you may find when testing an inventory management system. You likely will create more tests based on application requirements or user stories. Every inventory management system can function differently. Be sure to keep abreast of any design or functional changes within the application. Keeping your knowledge and test cases updated is critical to make testing more efficient and productive. 

How to Create Test Cases for Inventory Management Systems Using Test Management by Testsigma

Test Management by Testsigma is an Agentic-AI-driven codeless test management tool that helps you plan, design, execute, and track tests across your entire application lifecycle. Whether you’re creating a test case for inventory management system workflows like stock entry, order processing, or inventory reconciliation, Testsigma simplifies the process with Agentic AI support and zero-code configuration.

Here’s how you can manage your test cases for an inventory management system using Testsigma:

Step 1. Generate Inventory Test Cases with AI Agents

• Go to the Test Cases tab in the Test Management by Testsigma’s dashboard.
• Create a new folder named “Inventory Management” or similar to organize your test cases.
