Salesforce Platform Developer Practice Exam

Why would a developer use Test.startTest() and Test.stopTest()?

1. To avoid Apex code coverage requirements

2. To indicate test code for execution

3. To create an additional set of governor limits

4. To boost execution speed of the test

The correct answer is: To create an additional set of governor limits

Using Test.startTest() and Test.stopTest() is crucial in testing within the Salesforce platform, especially when it comes to governor limits and ensuring that tests accurately reflect production scenarios. When a developer invokes Test.startTest(), it effectively resets the governor limits for the code that is executed in the scope of the test. This means that the code executed between Test.startTest() and Test.stopTest() can consume a fresh set of the governor limits, which allows the developer to simulate conditions that might occur during actual implementation and utilize the maximum limits available for computation or DML operations without interference from prior test methods. This practice is beneficial because it enables developers to rigorously test how their code behaves when it is under the full load of what Salesforce allows, rather than being constrained by previous operations in the test. After Test.stopTest() is called, normal limits are restored, thus ensuring proper separation of test logic and a more accurate measurement of execution conditions. The other options don’t correctly capture the purpose of these methods in testing. Avoiding Apex code coverage requirements is not a function of these methods, nor do they specifically indicate test code for execution or boost execution speed. Instead, they play a critical role in managing and maximizing the resources available during the execution of
