PDI Leak Questions

ISV Package Development:

The ISV is developing a managed package.

They have an Apex class BodyFat with a method calculateBodyFat().

Requirement:

Ensure calculateBodyFat() is accessible by consumers outside the package namespace.

Solution:

To allow methods in a managed package to be accessible outside the package namespace, they must be declared as global.

Option B: Declare the class and method using the global access modifier.

Correct Approach.

Explanation:

Global Classes and Methods:

In managed packages, only classes and methods declared as global are accessible outside the package namespace.

Declaration:

global class BodyFat {

global void calculateBodyFat() {

// method implementation

}

}

Important Notes:

Public classes and methods in managed packages are accessible only within the namespace.

Global is required to expose the functionality to subscribers.

Unit tests in Salesforce are designed to test Apex code functionality and can execute certain operations within the testing context.

Option C: Generate a Visualforce PDF with getContentAsPDF

Explanation: In unit tests, you can generate a PDF from a Visualforce page using the getContentAsPDF() method. This is allowed within test methods and is a valid operation for unit testing.

When deploying Apex code to production, Salesforce requires that all Apex triggers have at least 1% code coverage and the overall code coverage must be at least 75%.

In this scenario:

The developer has a test class that covers 95% of the helper class.

The deployment fails because the trigger has 0% coverage.

The error message indicates that the trigger needs at least 1% coverage.

Solution:

Option A: Create a test class and methods to cover the Apex trigger.

Correct Action.

Explanation:

Write a test class that specifically tests the trigger's functionality.

Ensure that the trigger is executed within the test context.

This will increase the trigger's code coverage above the required 1%.
