Question 1

Which System.assert method should you use when you want to verify that two values are equal and display a custom failure message?

Accepted Answer

System.assertEquals()

Answer

System.assertEquals(expected, actual, message) verifies equality and accepts an optional third parameter for a custom failure message.

Question 2

What is the effect of calling Test.startTest() in an Apex test method?

Accepted Answer

It opens a new governor limit context for the code under test

Answer

Test.startTest() creates a fresh set of governor limits so the code between startTest/stopTest runs with its own independent limits.

Question 3

A developer needs to test a trigger that sends an outbound HTTP callout. Which class must be implemented to avoid a 'You have uncommitted work pending' error in the test?

Accepted Answer

HttpCalloutMock

Answer

Implementing HttpCalloutMock and registering it with Test.setMock() allows Apex tests to simulate HTTP responses without making real callouts.

Question 4

In the Apex debugger, what does the SOQL_EXECUTE_BEGIN log line indicate?

Accepted Answer

A SOQL query is about to be executed

Answer

SOQL_EXECUTE_BEGIN marks the start of a SOQL query execution in the debug log, while SOQL_EXECUTE_END marks its completion.

Question 5

Which debug log level produces the MOST detailed output and is therefore most useful for tracing complex logic, but also consumes the most storage?

Accepted Answer

FINEST

Answer

FINEST is the most verbose log level in Salesforce, capturing granular detail about code execution at the cost of larger log size.
