After the book is inserted, the code retrieves the newly inserted book, using the ID that was initially assigned to the book when it was inserted.
How is code coverage performed in apex class?
This code coverage is performed by the test classes. Test classes are the code snippets which test the functionality of other Apex class. Let us write a test class for one of our codes which we have written previously. We will write test class to cover our Trigger and Helper class code.
When do you need to rerun regression tests in apex?
