How can a developer check the test coverage of autolaunched Flows before deploying them in a change set?
As of Winter '20 (API version 47.0), Salesforce introduced the ability to test Autolaunched Flows with test coverage.
However, as of the current knowledge cutoff (2023-09), there is no direct way within the Salesforce UI to check the test coverage of autolaunched flows before deploying them via change sets.
To check the test coverage of flows, developers can use the Tooling API to query for test coverage.
Option A: Use SOQL and the Tooling API.
Correct Answer.
Developers can use the Tooling API to query for Flow test coverage information.
By executing a SOQL query on FlowTestCoverage and FlowVersionView objects via the Tooling API, developers can retrieve coverage data.
This allows checking flow test coverage programmatically before deployment.
The Flow Properties page does not provide test coverage information.
It allows configuring flow settings but not checking test coverage.
Option C: Use the Code Coverage Setup page.
Incorrect.
The Code Coverage page in Setup pertains to Apex code coverage, not Flow coverage.
Option D: Use the ApexTestResult class.
Incorrect.
The ApexTestResult class is used for Apex test results.
It does not provide information on Flow test coverage.
Conclusion:
To check the test coverage of autolaunched Flows before deploying them in a change set, a developer should use SOQL and the Tooling API, which is Option A.

Incorrect Options:
Option B: Use the Flow Properties page.
Incorrect.
A developer needs to have records with specific field values in order to test a new Apex class.
What should the developer do to ensure the data is available to the test?
To ensure that specific data is available in test methods, the developer should create test data within the test context.
Option B: Use Test.loadData() and reference a CSV file in a static resource.
Correct Approach.
Test.loadData() is a method that allows test methods to load test data from a CSV file stored as a static resource.
This method creates the records in the test context, ensuring that the data is available during the test execution.
Using a CSV file makes it easy to define multiple records with specific field values.
Usage Example:
@isTest
private class MyTestClass {
@isTest
static void testMethod() {
List<MyObject__c> testRecords = (List<MyObject__c>) Test.loadData(MyObject__c.sObjectType, 'MyTestData');
// Proceed with testing using testRecords
}
}
Where 'MyTestData' is the name of the static resource containing the CSV file.
Test.loadData() does not support loading data from JSON files or from the Documents object.
It uses CSV files stored as static resources.
Option C: Use Anonymous Apex to create the required data.
Not Effective for Testing.
Data created via Anonymous Apex is not available in test methods due to data isolation.
Test methods operate in their own context and cannot access data created outside the test unless SeeAllData=true is used, which is discouraged.
Option D: Use SOQL to query the org for the required data.
Not Recommended.
Test methods should not rely on existing org data.
Tests should create their own data to ensure consistency and avoid dependencies.
Using SeeAllData=true is discouraged.
Conclusion:
To ensure that records with specific field values are available in the test, the developer should use Test.loadData() with a CSV file stored in a static resource.
Therefore, Option B is the correct answer.
Options Not Suitable:
Option A: Use test.loadData() and reference a JSON file in Documents.
Incorrect.
A credit card company needs to implement the functionality for a service agent to process damaged or stolen credit cards. When the customers call in, the service agent must gather many pieces of information. A developer is tasked to implement this functionality.
What should the developer use to satisfy this requirement in the most efficient manner?
The requirement is for service agents to gather many pieces of information when processing damaged or stolen credit cards.
Option A: Screen-based Flow
Correct Answer.
A Screen Flow allows developers to build guided, interactive forms that collect information from users.
Flows can have multiple screens, validation rules, and branching logic.
They can be created declaratively without code, making them efficient to implement.
Benefits:
Efficient Development: No need for code.
User-Friendly: Provides a step-by-step interface.
Maintainable: Easy to update as requirements change.
Building a custom Lightning Component requires development effort.
For simple data collection, a Flow is more efficient.
Option C: Approval Process
Incorrect.
Approval Processes are used for routing records for approval, not for gathering information from users.
Option D: Apex Trigger
Incorrect.
Triggers run in the background and are not used for interactive user interfaces.
Conclusion:
The most efficient way to satisfy the requirement is to use a Screen-based Flow, which is Option A.
Incorrect Options:
Option B: Lightning Component
*Possible but Less Efficient.
