For deployment to production, individual Apex classes must achieve at least 75% code coverage, and Apex triggers must have at least one line of code covered by unit tests.

Common mistakes.

• C. Not all methods within a test class must use the @isTest annotation; only the class itself needs it, or individual methods can be marked testMethod if the class is not annotated.
• D. Test methods can be declared with the testMethod keyword, but they can also simply be public static methods within a class annotated with @isTest.
