@testVisible and @testSetup in salesforce

Hello Madhulika,

@testVisible: Some methods are declared as private so you won’t be able to call them outside the class. However, sometimes you really want to be able to invoke it from a unit test method.To resolve this, you can mark the method with a @TestVisible annotation. Then although it is still private, it is invokable from your unit test methods.

@testSetup: For most unit tests in Salesforce, we need to generate some test data. And for different test methods within one single test class, the required test data set is usually very close. In order to serve for this purpose, Salesforce has introduced TestSetup annotation. The data generated in TestSetup will be persisted for every test method within the test class to use. And the data will only be rolled back after the execution of the whole test class completes.Methods defined with the @testSetup annotation are used for creating common test records that are available for all test methods in the class.
Thanks.

@TestVisible Annotation.

This annotation enables a more permissive access level for running tests only. TestVisible annotation allow test methods to access private or protected members of another class outside the test class. These members include methods, member variables, and inner classes.
