NetSuite’s twice-yearly updates introduce new features, enhancements, and security improvements. However, each update can also impact customizations and configurations critical to your workflows. A robust regression testing strategy helps identify and mitigate these risks, ensuring that your ERP environment remains stable and reliable. Here’s a look at effective strategies for regression testing in NetSuite.
1. Prioritize Business-Critical Customizations
Focus on the customizations and scripts essential to your business operations. For example, prioritize custom SuiteScripts, workflows, integrations, and saved searches. Testing these core elements first ensures that the features crucial to day-to-day operations remain unaffected by the update.
2. Automate Key Tests with SuiteScript and Selenium
Automating tests for frequently used functionalities saves time and reduces human error. SuiteScript 2.0 is ideal for testing backend functionality and APIs, while Selenium is well-suited for automating UI tests. Combining both tools allows for end-to-end testing, covering both data handling and user interactions.
3. Maintain a Comprehensive Regression Test Suite
Build and maintain a regression suite that includes test cases for standard NetSuite functionality, custom workflows, and third-party integrations. Organize tests by modules (e.g., financials, CRM, inventory) so you can execute targeted regression tests based on the scope of the update.
4. Leverage NetSuite Release Preview
NetSuite provides a Release Preview environment, enabling you to test updates before they’re applied to your production instance. Use this environment to run your regression suite, catching potential issues early and allowing time for adjustments before the changes reach production.
5. Test Integrations and Data Flow
NetSuite often integrates with other systems (e.g., CRM, e-commerce). Regression tests should verify that these integrations remain intact, checking for seamless data transfer and validation. Any update could introduce changes affecting field mappings or data transformations, so testing these areas is crucial.
6. Validate Reports and Saved Searches
Reports and saved searches are frequently used for data analysis, and any discrepancies here could lead to poor decision-making. Include tests to validate report accuracy, saved search criteria, and data consistency after the update.
7. Execute Post-Update Validation in Production
After the update, conduct a round of quick validations in the production environment. Ensure critical workflows, permissions, and data records remain unaffected. For example, validate that users can still complete key transactions and access essential reports without issue.
8. Document and Continuously Update Test Cases
With each update, NetSuite may change how specific fields or forms function. Regularly update test cases to align with new NetSuite functionality, removing outdated cases and adding new ones as required. This continuous improvement keeps your regression suite relevant and effective.
Conclusion
A well-defined regression testing strategy prepares your NetSuite instance for updates while ensuring system stability and data integrity. By prioritizing automation, leveraging NetSuite’s Release Preview, and focusing on integrations, you can confidently navigate each update, keeping your ERP processes running smoothly.
