Maintain Your Platform Developer I Certification for Winter ’25

Steps to Fix the Issue:
1. Ensure Debug Statement Matches Exactly
- Trailhead might be expecting the debug log to include exactly the string Hello (case-sensitive and with no extra characters)
Ex: System.debug('Hello');
2. Avoid Concatenation or Extra Characters:
- Avoid concatenating the debug message with additional text like 'String: ' + str.
- Instead, directly debug the string itself.
3. Simplify Your Debugging Loop
for (String str : myIterableInstance)
{
System.debug(str); // Ensure only the string is printed
}
4. Check for Logging Levels:
- Ensure that the debug log level is set to include DEBUG statements during the test run.
5. Run the Test in a Clean Environment:
- Delete all previous logs.
- Execute only this test method to avoid confusion with other debug logs.
Updated Test Method :
@IsTest
public class MyIterableTest
{
@IsTest
static void testIterableForLoop()
{
// Prepare a test list of strings
List strings = new List{'Hello', 'World'};

// Create an instance of MyIterable
MyIterable myIterableInstance = new MyIterable(strings);

// Use a for-each loop to iterate over the MyIterable instance
for (String str : myIterableInstance)
{
System.debug(str); // Directly debug the string
}
}
}
Verify on Trailhead:
1. Run the test again in your Salesforce org.
2. Check the debug logs for the exact string Hello.
3. If Trailhead validation still fails, confirm that:
- Your org is correctly connected to Trailhead.
- The class name and method name match what Trailhead expects.
- There are no extra debug logs interfering with the validation.
