Salesforce Platform Developer Practice Exam

To test a new test class in a sandbox before deploying to production, a developer should use?

1. The REST API and ApexTestRun method.

2. The Apex Test Execution page in Salesforce Setup.

3. The Developer Console Test menu.

4. The Run Tests page in Salesforce Setup.

The correct answer is: The Apex Test Execution page in Salesforce Setup.

Using the Apex Test Execution page in Salesforce Setup is the recommended approach for testing a new test class in a sandbox environment before deploying it to production. This page allows developers to run Apex test classes and provides a user-friendly interface to view the results of the tests. It not only allows for the execution of specific test classes but also shows detailed results, including the pass/fail status and any debug logs that might have been generated during the test runs. Running tests in this manner is crucial in a sandbox environment, as it simulates the production environment closely, ensuring that the code behaves as expected before any deployment occurs. This approach also provides crucial insights into code coverage and potential issues that might arise in production, helping to maintain the integrity of the application. Other methods such as using the Developer Console might also allow for test executions, but they may not provide the comprehensive overview of test results across multiple classes as effectively as the Apex Test Execution page in Setup.
