Notes
In Salesforce, we use test classes to test our Apex code and ensure that it behaves correctly in different scenarios. Test classes are an essential part of the Salesforce development process because they allow developers to verify that their code meets the expected behavior and performance requirements before deploying it to production.
Here are some of the main reasons why we use test classes in Salesforce:
-
Verify functionality: Test classes help us to verify that our Apex code works as expected and produces the correct results. We can test different input values and scenarios to ensure that our code behaves correctly in different situations.
-
Ensure quality: By testing our code, we can identify and fix bugs before deploying the code to production. This helps to ensure that the quality of our code is high and that it meets the requirements of the business.
-
Meet Salesforce requirements: Salesforce requires that a minimum of 75% of all Apex code is covered by unit tests, and that all triggers and classes that are part of a managed package must have associated test classes. Test classes ensure that our code meets these requirements and can be deployed to production.
-
Facilitate collaboration: Test classes help to facilitate collaboration between developers and ensure that changes made by one developer do not break existing functionality. By testing code before deployment, we can catch issues early and collaborate on fixes before they cause problems in production.
Overall, test classes are an essential tool for Salesforce developers, enabling them to create high-quality code that meets the requirements of the business and performs reliably in production.
