after reading the document of PHPUnit to write the database test, we should first establish the base, mainly to write a setup function, which is my

protected function setUp() : void
{
    // mysql 
    $conn = $this->getConnection();
    // PDO 
    $pdo = $conn->getConnection();
    // set up tables
    $fixtureDataSet = $this->getDataSet();
    foreach ($fixtureDataSet->getTableNames() as $table) {
        // drop table
        $pdo->exec("DROP TABLE IF EXISTS `$table`;");
        // recreate table
        //Returns a table meta data object for the given table
        $meta = $fixtureDataSet->getTableMetaData($table);
        $create = "CREATE TABLE IF NOT EXISTS `$table` ";
        $cols = array();
        foreach ($meta->getColumns() as $col) {
            $cols[] = "`$col` VARCHAR(200)";
        }
        $create .= "(".implode(",", $cols).");";
        $pdo->exec($create);
    }
    parent::setUp();
}

but in this case, the fields that create the table are all varchar, and I think the class getColumns of $meta returns an array of strings, and I don"t know where to get the field definition information?

this is the xml file from MySQLdump
