Which two statements are true about using the @testSetup annotation in an Apex test class? Choose 2 answers

@testSetup methods run once per test class, inserting common test data that every test method can access, saving governor limits. They cannot be used in a class annotated with @isTest(SeeAllData=true); that combination is explicitly unsupported.

A. Records can be updated inside a test method; updates are isolated to that method.

C. testSetup executes only once per class, so its DML counts once, not once per test method.

1. Apex Developer Guide, “Test Setup Methods” (v59.0) – runs once, data shared, cannot be used with SeeAllData=true.

2. Apex Developer Guide, “Isolation of Test Data” (v59.0) – explains visibility and mutability of setup records within individual test methods.
