Answer A

A developer creates an Apex class that includes private methods. What can the developer do to ensure that the private methods can be accessed by the test class?

A. Add the TestVisble attribute to the Apex class
B. Add the SeeAllData attribute to the test methods.
C. Add the TestVisible attribute to the apex methods.
D. Add the SeeAllData attribute to the test class

Answer C

Considerations for the @IsTest(SeeAllData=true) Annotation

• If a test class is defined with the @isTest(SeeAllData=true) annotation, the annotation applies to all its test methods whether the test methods are defined with the @isTest annotation or the (deprecated) testMethod keyword.
• The @isTest(SeeAllData=true) annotation is used to open up data access when applied at the class or method level. However, if the containing class has been annotated with @isTest(SeeAllData=true), annotating a method with @isTest(SeeAllData=false) is ignored for that method. In this case, that method still has access to all the data in the organization. Annotating a method with @isTest(SeeAllData=true) overrides, for that method, an @isTest(SeeAllData=false) annotation on the class.
• @isTest(SeeAllData=true) and @isTest(isParallel=true) annotations cannot be used together on the same Apex method.

 

What is the proper process for an Apex Unit Test?

A. Query for test data using SeeAllData = true. Call the method being tested. Verify that the results are correct.
B. Query for test data using SeeAllData = true. Execute runAllTests(). Verify that the results are correct.
C. Create data for testing. Execute runAllTests(). Verify that the results are correct.
D. Create data for testing. Call the method being tested. Verify that the results are correct.

What is a capability of a StandardSetController?Choose 2 answers

A. It allows pages to perform mass updates of records
B. It allows pages to perform pagination with large record sets
C. It enforces field-level security when reading large record sets
D. It extends the functionality of a standard or custom controller

Answer A, B

StandardSetController objects allow you to create list controllers similar to, or as extensions of, the pre-built Visualforce list controllers provided by Salesforce.
The StandardSetController class also contains a prototype object. This is a single sObject contained within the Visualforce StandardSetController class. If the prototype object's fields are set, those values are used during the save action, meaning that the values are applied to every record in the set controller's collection. This is useful for writing pages that perform mass updates (applying identical changes to fields within a collection of objects).
public class opportunityList2Con {
     // ApexPages.StandardSetController must be instantiated
     // for standard list controllers
     public ApexPages.StandardSetController setCon {
          get {
               if(setCon == null) {
                    setCon = new ApexPages.StandardSetController(Database.getQueryLocator(
                              [SELECT Name, CloseDate FROM Opportunity]));

               }
               return setCon;
          }
          set;

     }

     // Initialize setCon and return a list of records
     public List<Opportunity> getOpportunities() {
          return (List<Opportunity>) setCon.getRecords();
     }
}

 

<apex:page controller="opportunityList2Con">
     <apex:pageBlock>
          <apex:pageBlockTable value="{!opportunities}" var="o">

               <apex:column value="{!o.Name}"/>
               <apex:column value="{!o.CloseDate}"/>
          </apex:pageBlockTable>
     </apex:pageBlock>
</apex:page>
