NEW QUESTION # 66
A developer notices the execution of all the test methods in a class takes a long time to run, due to the initial setup of all the test data that is needed to perform the tests. What should the developer do to speed up test execution?
Answer: C
Explanation:
Using the @testSetup annotation to define a method that creates test data before the tests run can significantly speed up test execution by reducing the setup time for each test method in the class. This method runs once before any test method in the class and can be used by all test methods.
NEW QUESTION # 67
Which two best practices should the developer implement to optimize this code? Choose 2 answers
Answer: B,D
Explanation:
To optimize the code in question, it's important to follow best practices that reduce the number of SOQL queries and DML statements within loops, as these can quickly consume governor limits and lead to inefficiencies. Option C is correct because using a collection to hold records and performing a single DML operation outside of loops reduces the number of DML operations, which is a best practice for bulkifying code in Salesforce. Option D is also correct because querying records outside of a loop prevents hitting SOQL governor limits and makes the code more efficient. Options A and B are not correct in the context provided, as there isn't enough information to determine if changing the trigger context is necessary, and removing the DML statement altogether may not be feasible if the logic requires data to be persisted.
