Salesforce B2C Commerce Developer Practice Exam

Regression testing is crucial for Salesforce B2C Commerce deployments because it ensures that any recent changes or updates to the code do not adversely affect the existing functionality of the e-commerce platform. After modifications such as new features, bug fixes, or updates, regression testing allows developers to verify that the software remains stable and performs as expected. This type of testing helps in identifying any unintended side effects that might arise from changes, ensuring a seamless user experience remains intact.

While user acceptance testing is important for validating that the solution meets business needs from a user's perspective, and load testing is essential to ensure the platform can handle the expected number of users and transactions, the primary focus during deployments is on regression testing. Integration testing is also significant as it validates that different system components work together, but in the context of a specific deployment phase, ensuring that previous functionalities continue to work is the primary concern, which is covered effectively by regression testing.
