What is the minimum Apex code coverage requirement for a user story?

The minimum Apex code coverage requirement for deploying Apex code in Salesforce, including user stories, is 75%. This level of coverage is essential because it ensures that a significant portion of the code has been tested, which is indicative of the code's reliability and quality. Code coverage measures the percentage of code that has been covered by tests, helping to identify untested areas that may contain bugs or functionality issues.

In the context of Salesforce development best practices, achieving 75% coverage not only pertains to individual classes and triggers but also to the code being deployed to production. This requirement reinforces the importance of writing comprehensive tests that validate the behavior of the code across various scenarios. It ensures that critical paths of the application are functioning as expected before the code is released into a live environment, thereby minimizing potential disruptions.

While other percentages, such as 50%, 80%, or 90%, may be discussed in different contexts or for specific use cases, they do not represent the standard minimum requirement for successful deployment within the Salesforce ecosystem. Therefore, aiming for 75% coverage is a key benchmark for developers to meet when working with Apex code in user stories.
