Salesforce单元测试Assert语句失败，Apex逻辑未触发求助

First, let's pinpoint the core issue: your debug logs show the Case's OwnerId hasn't actually changed to the Queue ID after your update DML. That means the condition o.OwnerId != oldMap.get(o.Id).OwnerId in wmgRemoveOldGroupQueue never evaluates to true, so the field never gets cleared—hence your assert fails.

Root Causes & Fixes #

1. Your Queue isn't configured to handle the WMG Case Record Type #

When you create a Queue in Salesforce, you have to explicitly associate it with the record types of the objects it should own. Your test creates a QueueSObject but only links it to the Case object, not the specific WMG_Operations_Workflow record type. Salesforce blocks assigning a record to a Queue that doesn't support its record type, so your update silently fails to change the OwnerId.

Fix the Queue configuration in your test:

System.runAs(thisUser) {
    QueuesObject q = new QueueSObject(
        QueueID = testGroup.Id,
        SObjectType = 'Case',
        RecordTypeId = wmgRecordTypeId // Add this line to link the Queue to your record type
    );
    insert q;
}

2. Verify the Update Actually Changes the Owner #

Add an extra assert right after your test query to confirm the OwnerId was updated. This will quickly confirm if the DML is working as expected:

case r = [SELECT id, Ownerid, ANN_Accepted_From_Queue__c FROM Case WHERE Id = :newCase.Id];
// Add this to validate Owner change first
System.assertEquals(testGroup.Id, r.OwnerId, 'Case should be owned by the test Queue');
System.assertEquals('', r.ANN_Accepted_From_Queue__c, assertMsg);

3. Permissions Might Be Blocking the Owner Transfer #

The user running the test (in your code, thisUser) needs the Transfer Records permission, plus access to the test Queue. If you're not using an admin user, create a test user with full permissions to avoid permission-related blocks:

// Create an admin test user (simplified example)
Profile adminProfile = [SELECT Id FROM Profile WHERE Name = 'System Administrator'];
User testAdmin = new User(
    ProfileId = adminProfile.Id,
    Username = 'testadmin@example.com',
    Email = 'testadmin@example.com',
    LastName = 'Admin',
    FirstName = 'Test',
    Alias = 'tadmin',
    TimeZoneSidKey = 'America/Los_Angeles',
    LocaleSidKey = 'en_US',
    EmailEncodingKey = 'UTF-8',
    LanguageLocaleKey = 'en_US'
);
insert testAdmin;

// Run the Queue setup and update as this admin
System.runAs(testAdmin) {
    QueuesObject q = new QueueSObject(
        QueueID = testGroup.Id,
        SObjectType = 'Case',
        RecordTypeId = wmgRecordTypeId
    );
    insert q;
    
    case newCase = [SELECT id, Ownerid FROM Case WHERE Id = :c.Id];
    newCase.OwnerId = testGroup.Id;
    update newCase;
}

4. Add Safeguards in Your Logic Class #

To avoid null pointer exceptions (in case a record in newMap doesn't exist in oldMap, though unlikely for updates), modify your loop to check if oldMap contains the Case ID first:

for (Case o : newMap.values()) {
    if (oldMap.containsKey(o.Id)) { // Add this check
        Case oldCase = oldMap.get(o.Id);
        system.debug('o.OwnerId == '+o.OwnerId+' oldCase.OwnerId =='+oldCase.OwnerId);
        system.debug('o.RecordTypeId '+o.RecordTypeId+ 'wmgRecordTypeId'+wmgRecordTypeId);
        if (o.RecordTypeId == wmgRecordTypeId && !((String)o.OwnerId).startsWith('005') && (o.OwnerId != oldCase.OwnerId)) {
            o.ANN_Accepted_From_Queue__c = '';
        }
        system.debug('o.ANN_Accepted_From_Queue__c' +o.ANN_Accepted_From_Queue__c);
    }
}

Final Notes #

Start with verifying the OwnerId change first—if that assert fails, the Queue configuration/permissions are definitely your issue. Fixing that will make your original assert pass once the logic triggers as expected.
