A developer has a Batch Apex process, Batch_Account_Sales, that updates the sales amount for 10,000 Accounts on a nightly basis. The Batch Apex works as designed In the sandbox. However, the developer cannot get code coverage on the Batch Apex class.The test class is below: What is causing the code coverage problem?

The executeBatch must fail within test. startTest ( ) and – test. stopTest().

The batch process will not recognize new accounts created in the same session

The account creation already sets the sates amount to 0.

The executeBatch must fail within test. startTest ( ) and – test. stopTest().

The batch needs more than one account record created.

Universal Containers has an Apex trigger on Account that creates an Account Plan record when an Account is marked as a Customer. Recently a workflow rule was added so that whenever an Account is marked as a Customer, a 'CustomerSince' date field is updated with today's date.Since the addition of the workflow rule, two Account Plan records are created whenever the Account is marked as a Customer.What might cause this to happen?

The workflow rule is configured to evaluate when a record is created and every time it is edited.

The workflow rule field update is marked as 'Re-evaluate Workflow Rules After Field Change."

The Apex trigger does not use a static variable to ensure it only fires once.

The Apex trigger is not bulk safe and calls insert inside of a for loop.

A developer is working with existing functionality that tracks how many times a stage has changed for an Opportunity. When the opportunity's stage is changed, a workflow rule is fired to increase the value of a filed by one.
