How to run a single seeder during unit test?

Database seeds are simple classes that must have a run() method, and extend CodeIgniter\Database\Seeder. Within the run() the class can create any form of data that it needs to. It has access to the database connection and the forge through $this->db and $this->forge, respectively. Seed files must be stored within the app/Database/Seeds directory. The name of the file must match the name of the class.
