QUESTION: 18 Topic: 1, Exam Pool A

Which two statements are true about using the @testSetup annotation in an Apex test class? (Choose two.)

The @testSetup annotation cannot be used when the @isTest(SeeAllData=True) annotation is used.
Test data is inserted once for all test methods in a class.
Records created in the @testSetup method cannot be updates in individual test methods.
The @testSetup method is automatically executed before each test method in the test class is executed.

Answer(s): B,C

Explanation:

The @testSetup annotation is used to create a common set of records that can be used across all test methods in a test class. The primary benefit of using this annotation is to reduce the amount of redundant setup code needed in each individual test method. The @testSetup method is executed once per test class before any test methods are executed. The created data is available to all test methods in the class, but it cannot be updated by individual test methods.

Option A is incorrect because the @testSetup annotation can be used regardless of the @isTest(SeeAllData=True) annotation.

Option D is incorrect because the @testSetup method is only executed once per test class, not before each individual test method.
