Try this line:

$doctor_daily=TestingType::join('report_doctor_company_daily_test', 'testing_types.id', '=', 'report_doctor_company_daily_test.test_id')
                          ->join('doctor', 'report_doctor_company_daily_test.doctor_id', '=','doctor.id')
                          ->groupBy('testing_types.id')
                          ->select('report_doctor_company_daily_test.test_id','testing_types.testing_name','doctor.first_name','doctor.last_name',DB::raw('SUM( report_doctor_company_daily_test.test_price )')
                          ->get();

Your mysql version is 5.7+, so check this reference

MySQL 5.7.5 and up implements detection of functional dependence. If the ONLY_FULL_GROUP_BY SQL mode is enabled (which it is by default), MySQL rejects queries for which the select list

so check the config/database.php, if your mysql configuration strict is true, you need to disabled the ONLY_FULL_GROUP_BY, add modes like this:

'modes' => [
            //'ONLY_FULL_GROUP_BY',
            'STRICT_TRANS_TABLES',
            'NO_ZERO_IN_DATE',
            'NO_ZERO_DATE',
            'ERROR_FOR_DIVISION_BY_ZERO',
            'NO_AUTO_CREATE_USER',
            'NO_ENGINE_SUBSTITUTION'
           ],

or you can just use any_value method for the selected columns:

PS: any_value does not exist on MariaDB

->selectRaw('ANY_VALUE(report_doctor_company_daily_test.test_id),
    ANY_VALUE(testing_types.testing_name),
    ANY_VALUE(doctor.first_name),
    ANY_VALUE(doctor.last_name),
    SUM( report_doctor_company_daily_test.test_price')
