There are two ways to achieve these requirements:
Simulate the Removalservice.rm method itself.

Since both of these methods are very important in unit testing, we will review both approaches at the same time.

Let's start with a simple case where multiple known table has the same schema and can be mapped to the same entity. Then, in the next study, we'll discuss a complex situation where we might dynamically build tables that have the same schema, if you use JPA.
Assuming that the Test_a,test_b and Test_c tables have the same table structure, that is, the schema is the same, we cannot map it to the same entity because each entity class is mapped to a table. If we don't want to write duplicate code, w
