SuiteScript Unit Testing

Introduction to SuiteScript and Unit Testing

SuiteScript is a powerful tool for customizing and automating workflows in NetSuite. To ensure the reliability and correctness of your SuiteScript code, unit testing is essential. Unit testing involves testing individual units of code to validate that each unit performs as expected. For SuiteScript, Jest is a popular testing framework that allows developers to write robust test cases efficiently.

Setting Up Jest for SuiteScript

Before you start writing tests, you need to set up Jest in your project. Follow these steps to get started:

• Install Node.js if you haven't already. Jest is a Node.js framework.
• Create a new Node.js project using npm init.
• Install Jest using npm by running npm install --save-dev jest.
• Configure your package.json to include a test script:

Writing Your First SuiteScript Unit Test with Jest

Let's write a simple unit test for a SuiteScript function. Suppose you have a function that adds two numbers:

To test this function using Jest, create a test file with a .test.js extension:

Running Your Tests

With your test file in place, you can run your tests using the following command:

npm test

This command will execute all test files in your project and display the results in the terminal.

Advanced Jest Features for SuiteScript

Jest offers several advanced features that can enhance your SuiteScript unit testing:

• Mocking: Jest allows you to mock functions and modules, making it easier to isolate the code under test.
• Coverage Reports: You can generate code coverage reports to identify untested parts of your codebase.
• Watch Mode: Jest can run in watch mode to automatically rerun tests when files change.
