What is a recommended way to test code changes in Salesforce Commerce Cloud?

Testing code changes in Salesforce Commerce Cloud through a sandbox instance is a recommended and effective approach. A sandbox environment allows developers to create, test, and iterate on their code without impacting the live production environment. This helps ensure that any changes made are thoroughly vetted before being deployed.

The sandbox is an isolated environment that mirrors the production setup, enabling developers to simulate real-world scenarios and test the functionality of code changes using all the features of the platform. It allows for testing with various configurations and scenarios, including different product data, customer information, and payment methods.

Using a sandbox instance minimizes the risk of introducing bugs or issues into the live site, where code errors could lead to outages, degraded performance, or poor customer experiences. This practice promotes a more stable and reliable production environment, as only thoroughly tested code gets deployed.

While other options might seem valid, they are not practical or advisable. Testing on a live production environment could lead to immediate and detrimental impacts on users. Utilizing historical data alone may not replicate live site conditions and may miss new scenarios. Manually checking each line of code would be overly time-consuming and inefficient in a real-world application development cycle, lacking automated testing benefits.
