What type of tests can be performed to ensure the reliability of SFCC applications?

The choice of unit tests, integration tests, and end-to-end tests is particularly relevant for ensuring the reliability of Salesforce Commerce Cloud (SFCC) applications.

Unit tests focus on verifying the smallest parts of the application in isolation, ensuring that individual components behave as expected. This helps identify bugs early in the development process and ensures that each unit of code is functioning correctly before it is integrated with other components.

Integration tests take this a step further by examining the interactions between different modules or services. In the context of SFCC applications, this could involve testing how various services such as payment processing or product catalog interacts with one another. This type of testing is crucial for identifying issues that might not be visible when testing components in isolation.

End-to-end tests validate the complete workflow of the application from start to finish in a real-world scenario. This ensures that all the integrated components work together seamlessly and that the application provides a coherent experience to users, from browsing products to completing a purchase.

Other options may include tests that serve specific purposes, such as performance or security testing; however, the combination of unit, integration, and end-to-end tests provides a comprehensive approach to testing that covers the fundamental levels necessary for reliable application development in SFCC.
