Background: Integrating e-commerce platforms with Enterprise Resource Planning (ERP) systems is crucial for businesses aiming to enhance operational efficiency and deliver a better customer experience. This enables the synchronization of real-time data between online sales channels and backend operations such as inventory management, order processing, financial accounting and customer relationship management. For a Software Testing project, ensuring the reliability and functionality of this integration is paramount, as it involves validating that data flows correctly between the systems, processes are automated accurately, and there are no disruptions in business operations.
Strategy:
1. Assessment and Requirement Gathering:
1.1 Analysis: Determined the business requirements and objectives for the integration. Identify key data points and processes that need to be synchronized.
1.2 System Evaluation: Evaluated the current eCommerce and ERP systems to understand their integration capabilities and limitations.
1.3 Prioritize Requirements: Identified complex areas and high-priority business requirements give the highest priority
2. Understanding Business Requirements
Goals and Objectives: The team clearly defined what the integration aims to achieve. For this project, it was identified as streamlining the order processing and enhancing the customer experience. Therefore, gathering inputs from relevant stakeholders to understand their expectations and requirements was done in this stage.
3. Test Planning
The Test Plan was prepared by identifying the scope and out-of-scope features. Apart from the main things of a Test plan, the communication channel, test templates, and test environment setup were finalized initially.
Data Synchronization: Ensuring real-time data updates between eCommerce and ERP systems.
Order Processing: Validating the end-to-end order lifecycle, from placement to fulfillment.
Inventory Management: Checking accurate inventory updates and stock levels.
Financial Transactions: Verifying accurate and timely financial entries and updates.
There were workflows to do approval and rejections and it was handled via the Admin module. This had to be done based on the user's segregation. Therefore, this is also taken for the Test scope.
4. Test Case Development:
4.1 Functional and Integration Testing: The team developed test cases to validate the functionality of the integration. Ensure that data synchronization, order processing, inventory updates, and financial transactions work as expected.
As the Order processing was flexible with cancellations/rejections, test cases were developed to test the accuracy of inventory and financial entries. Apart from that many edge cases were considered to test the system's restrictions for invalid user transactions that can cause a major impact to the inventory and finance modules.
Apart from verifying the flow, the team developed many negative test cases to identify
whether the user can skip certain steps and complete the flow
whether the user can make certain modifications to the utilized data. (Ex: Changing item price details when that item was utilized in a Sales invoice, etc...) At that time there was no version management for these modifications.
whether the user can do flow steps without going through the flow's order
These verifications were heavily dependent on the responsibility of the Admin user. Therefore, most of these test cases were developed as System Limitations. Many improvements were suggested along with a detailed audit log.
For eCommerce:
4.2 Apart from verifying the order processing of the eCommerce system, test cases were generated for UI/UX Testing and Compatibility Testing. Based on the client's requirements, browsers and devices were selected.
4.3 Test cases for data mapping
The team developed test cases specifically for data mapping validation. Test the end-to-end data flow to ensure data is accurately transferred and transformed.
For this project, the team did not do Performance and Security testing. We plan to include "Business Intelligence Testing" for the next projects.
Challenges & Solutions:
Incorrect Data Mapping: Data fields in the eCommerce platform are not correctly mapped to corresponding fields in the ERP system. There were some differences in data formats, structures, or values between the eCommerce platform and ERP system.
As the solution, detailed Mapping Documentation was prepared and its validation was checked initially. The data mapping documentation was reviewed and approved by all stakeholders.
Handling many critical issues: The team had to handle many issues and most of them were encountered due to unavailability of restrictions and version management. Therefore, some master data were overridden with the latest modifications and there were many inconsistencies in the final reports. Some transactions were crashed without giving proper error messages. And there were no revert mechanisms to handle certain finance transactions.
As the solution, once the team identified these critical issues, they handled test data with proper identifications. Testing of the negative test cases and edge cases was done at the last after completing the happy paths.
Issues in workflows: The issues and weaknesses in the workflows brought up many distractions to testing. As a solution, this testing is also done at the last stage after identifying the status of the application. The team suggested many recommendations to implement the restrictions to avoid flaws in the workflows.
Results:
Optimized Efficiency: The incorporation of the systems made sure that processes were simplified, leading to less manual data entry and lesser errors. Order processing lengths were significantly decreased, causing order delivery to happen quickly and delighting customers.
Real-time Data Synchronization: This well-tried integration ensured timely updates between eCommerce and ERP systems by providing correct levels of inventories, financial details, and information about clients.
Better Reporting and Analytics: The integration of data has allowed for detailed analysis and report generation that provides knowledge on sales patterns, stock management, and financial performance.
Conclusion:
The integration of eCommerce platforms with ERP systems is essential for businesses looking to enhance their operational efficiency and customer experience. A well-planned and thoroughly tested integration can lead to significant improvements in data accuracy, process automation, and business agility. By addressing challenges such as data inconsistencies, integration downtime, scalability, and security risks through meticulous testing and robust solutions, businesses can achieve a reliable integration that drives growth and success.
