Salesforce DEX-450 Exam - Topic 5 Question 105 Discussion

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.

Test.loadData() Method

Static Resources

Options Not Suitable:

Option A: Use test.loadData() and reference a JSON file in Documents.

Incorrect.
