Roll-Up summary fields are a great way to perform calculations on a set of detail records in a master-detail relationship. roll-up summary fields that automatically display a value on a master record based on the values of records in a detail record

41. What does the View State represent in a Visualforce page?

Visualforce pages that contain a form component also contain an encrypted, hidden form field that encapsulates the view state of the page. This view state is automatically created, and as its name suggests, it holds the state of the page – state that includes the components, field values and controller state

42. What are the advantages of using External Id fields?

When importing custom objects, solutions, or person accounts, you can use external IDs to prevent the import from creating duplicate records. An external ID is a custom field that has the External ID attribute, meaning that it contains unique record identifiers from a system outside of Salesforce.

43. What are the differences between static and non-static variables in Apex?

Static methods, variables, and initialization code have these characteristics.

  • They’re associated with a class.
  • They’re allowed only in outer classes.
  • They’re initialized only when a class is loaded.
  • They aren’t transmitted as part of the view state for a Visualforce page.

Instance methods, member variables, and initialization code have these characteristics.

  • They’re associated with a particular object.
  • They have no definition modifier.
  • They’re created with every object instantiated from the class in which they’re declared.

Local variables have these characteristics.

  • They’re associated with the block of code in which they’re declared.
  • They must be initialized before they’re used.

The key methods to use in your unit tests are the system.assert() methods. There are three types of system.assert() methods.

  • System.assert(condition)
  • System.assertEquals(x,y)
  • System.assertNotEquals(x,y)

For the security review, every test method must have at least one system.assert() method. We need use assert methods not only for the pass the security review but also as a best practice. It will be help us to keep track the failures of Apex classes or triggers.

45. Difference between Workflows and Triggers?

Workflow

  • Workflow is automated process that fired an action based on Evaluation criteria and rule criteria.
  • can access a workflow across the object.
