Study Notes

Aura Components and Flows

To display a Flow named "accountOnboarding" created in Flow Builder within an Aura component, a developer should use the lightning:flow tag.

Debugging Apex Triggers

To troubleshoot an Apex trigger causing record duplication, the most effective approach is to use the Apex Interactive Debugger. This allows stepping through the code line-by-line and identifying the issue.

Implementing Decommissioning Logic

A Validation Rule should be used to ensure only decommissioned containers can be deleted. The validation rule should check the "Status" field and only allow deletion if the value is "Decommissioned".

Validating Lead Email Addresses

To enforce a valid email address for new leads with additional automation, the best solution is to use a before-save Apex trigger on the Lead object. The trigger should validate the email address using a built-in function and display an error message if it is invalid.

Source-Driven Development

For source-driven development with independent work and different org configurations, Scratch Orgs are the recommended type of org.

Custom Form for Account Record

To allow users to complete a form on an Account record that creates a record for a custom object, a Dynamic Action can be added to the Account Record Page.

Preventing Record Creation with Conditions

The correct implementation to prevent the creation of Request__c records under specific conditions is to use a before insert trigger on the Request__c object. The trigger should call a helper class like RequestLogic to validate the records before they are inserted.

Opportunity Follow-Up Task Automation

The most efficient way to automatically create a follow-up task for each new Opportunity, assigned to the Opportunity Owner, is using a Record-triggered flow on Opportunity. The flow can be triggered on "Opportunity: Created" and create the Task record with the correct information.

Retrieving User's Default Opportunity Record Type

To get the current user's default Opportunity record type, a developer can use the schema.userinfo.opportunity.getDefaultRecordType() method.

Master-Detail Relationship and Automation

In a master-detail relationship between Account and Branch, the following are true:
- Rollup summary fields on the parent record (Account) will trigger a Save operation on the parent record.
- Duplicate rules are executed only once all operations are committed to the database.
- A trigger may execute multiple times during a transaction.
- Validation rules will not cause the trigger to fire again.

Handling Unique Custom Fields

To handle a unique custom field (e.g., PrimaryId__c) on a custom object (e.g., Candidate__c), the best option is to mark the field as an External ID. This ensures that Salesforce properly handles uniqueness and prevents duplicate data.

Adding Test Accounts to Developer Edition

To add test accounts to a Developer Edition org, use the Data Loader tool to import a CSV file containing the new account data.

Accessing Standard Price Book in Test Class

To access the standard price book in a test class covering an OpportunityLineItem trigger, use the Test.getStandardPricebookId() method.

Lightning Component for Contact Creation

The correct Lightning component tag for creating a Contact record with a custom field (Salary__c) is lightning:input type="currency" value="Salary__c">.

Code Coverage and Test Classes

Viewing Code Coverage:
- Code coverage percentage can be viewed in the Overall Code Coverage panel within the Developer Console Tests tab.
- The Class Test Percentage tab on the Apex Class list view in Salesforce Setup also shows coverage.
- The Code Coverage column in the Apex Classes page list view displays coverage information.
Test Class Scenarios:
- To resolve a coverage warning for a helper class, increase the test class coverage on the helper class.
- A separate test class should be created to cover the Apex trigger directly.
- Failing test methods should not be removed from the test class but fixed to improve coverage.
- Using the "Run All Tests" method only executes existing tests and won't automatically create new tests.
