Considerations for the @IsTest(SeeAllData=true) Annotation

• If a test class is defined with the @isTest(SeeAllData=true) annotation, the annotation applies to all its test methods whether the test methods are defined with the @isTest annotation or the (deprecated) testMethod keyword.
• The @isTest(SeeAllData=true) annotation is used to open up data access when applied at the class or method level. However, if the containing class has been annotated with @isTest(SeeAllData=true), annotating a method with @isTest(SeeAllData=false) is ignored for that method. In this case, that method still has access to all the data in the organization. Annotating a method with @isTest(SeeAllData=true) overrides, for that method, an @isTest(SeeAllData=false) annotation on the class.
• @isTest(SeeAllData=true) and @isTest(isParallel=true) annotations cannot be used together on the same Apex method.

 

What is the proper process for an Apex Unit Test?

A. Query for test data using SeeAllData = true. Call the method being tested. Verify that the results are correct.
B. Query for test data using SeeAllData = true. Execute runAllTests(). Verify that the results are correct.
C. Create data for testing. Execute runAllTests(). Verify that the results are correct.
D. Create data for testing. Call the method being tested. Verify that the results are correct.
