Unit testing is a method of software testing that verifies the individual parts of your code to ensure they are working correctly. This can help you catch and fix bugs early in the development process, making your code more reliable and easier to maintain. In the context of SuiteScripts, you can use your preferred JavaScript testing framework to test your scripts. One commonly used framework is Jest. You can use Node.js to run your tests. When testing SuiteScripts, you might find it helpful to use dependency injection. This is a technique where you pass the dependencies of a function as arguments, which makes it easier to replace them with mock objects in your tests. This can be particularly useful when you need to mock the NetSuite API modules. However, it's important to note that you should focus on testing your own code, not the SuiteScript API itself. For example, if you have a function that simply calls a SuiteScript API function, there's no need to test it because you're essentially just re-testing the API. To mock modules in your tests, you can use a virtual mock at the top of your test suite. This allows you to replace the real module with a mock version that you can control. While unit testing can require more work upfront, it can save you time and effort in the long run by helping you catch and fix bugs early. It also helps ensure that your scripts continue to work correctly in the future, even as you make changes to your code.
