Testing customizations in NetSuite is crucial for maintaining the integrity of your system and ensuring that new features or changes don’t disrupt daily operations. There are several types of testing that organizations should perform when implementing or updating NetSuite customizations:
- Unit Testing: This is the first step in the testing process, where individual components or scripts are tested in isolation. The goal of unit testing is to ensure that each individual script or feature works as expected on its own. For example, if you’ve created a custom SuiteScript to calculate discounts on sales orders, unit testing would focus on verifying that this script runs correctly under various conditions.
- Integration Testing: Once individual components pass unit testing, integration testing is performed to ensure that different parts of the system work together as expected. In a system like NetSuite, which often involves data passing between various modules such as CRM, financials, and inventory, integration testing is essential to identify any issues that might arise when components interact. For example, testing might ensure that a custom pricing script correctly pulls data from your inventory and pricing tables.
- Regression Testing: Any time changes are made to NetSuite, such as adding customizations or applying system updates, regression testing is necessary to verify that the changes do not negatively affect existing functionality. Automated regression testing tools can be useful here, as they can quickly run through a series of test cases to ensure that everything still works as expected after changes.
By combining these different testing types, you ensure that your customizations are stable, functional, and free from bugs before they go live.
