Salesforce Test Classes Best Practices
Use Descriptive Names: Name test classes clearly to indicate
what functionality they are testing.
Isolate Test Data: Create test data within the test class to
ensure tests are independent of data created in other tests.
Use @TestSetup: Use @TestSetup methods to create common
test data for multiple test methods, improving efficiency.
Use System.assert(): Assert expected outcomes using
System.assert() methods to validate behavior.
Test Positive and Negative Cases: Cover both positive
(expected) and negative (unexpected) scenarios in your test
methods.
Avoid Hardcoding IDs: Use Salesforce's built-in Id creation
methods or query for record IDs dynamically to avoid
hardcoding IDs.
Test Governor Limits: Ensure tests don't exceed Salesforce's
governor limits to prevent deployment failures.
