I am trying to write unit test for a a trigger which calls batch apex which performs callout and updates the response to certain record.

Trigger's psuedo code looks like:

trigger AccountTrigger on Account (after update) {
    if(myCondition) {
        Database.executeBatch(new MyBatchClass(), 1);
    }
}

And batch is:

public class MyBatchClass implements Database.Batchable<SObject>, 
    Database.AllowsCallouts {
    
    // only relevant execute method
    public void execute(Database.BatchableContext batchableContext, 
    List<Account> accounts) {

        for(Account account: accounts) {

            // make http request callout

            // based on response update account
        }
    }
}

When I run my test test, it gives me error as:

System.CalloutException: You have uncommitted work pending. Please commit or rollback before calling out

From the related question, I understand that Database.executeBatch is treated as a DML. When implementing this solution, I get:

System.CalloutException: Callout from triggers are currently not supported.

Please suggest any workaround or point towards any gap in the design. Any insight is highly appreciated.
