Hi,
Please find the solution.

@isTest
public class SendmailcopyTest {
    public static testMethod Void startTest(){
        Opportunity testOpportunity = new Opportunity(
            StageName = 'Sourcing Demand',
            CloseDate = Date.today(),
            Name = 'Test Opportunity'
        );
        insert testOpportunity;
        system.debug('testOpportunity::'+testOpportunity);

        Test.startTest();
        Sendmailcopy obj = new Sendmailcopy();
        Database.executeBatch(obj);
        Test.stopTest();
        
    }

}

        Test.startTest();
        Sendmailcopy smc = new Sendmailcopy();
