Step 2: The HSQL DB schema and data scripts in the src/test/resources folder.

sql/schema.sql

CREATE TABLE tbl_person
(     person_id int NOT NULL
    , person_gender varchar(6) NOT NULL
    , person_name varchar(100) NOT NULL
    , person_age int NOT NULL
);

CREATE UNIQUE INDEX idx_tbl_person ON tbl_person(person_id)

CREATE TABLE tbl_person

( person_id int NOT NULL

, person_gender varchar(6) NOT NULL

, person_name varchar(100) NOT NULL

, person_age int NOT NULL

);

CREATE UNIQUE INDEX idx_tbl_person ON tbl_person(person_id)

sql/data.sql

INSERT INTO tbl_person (person_id, person_gender, person_name, person_age)
        VALUES ( 1, 'MALE', 'John', 23);

INSERT INTO tbl_person (person_id, person_gender, person_name, person_age)
        VALUES ( 2, 'FEMALE', 'Mary', 23);

INSERT INTO tbl_person (person_id, person_gender, person_name, person_age)

VALUES ( 1, 'MALE', 'John', 23);

INSERT INTO tbl_person (person_id, person_gender, person_name, person_age)

VALUES ( 2, 'FEMALE', 'Mary', 23);

Step 3: The Spring configuration for the unit tests in the src/test/java folder.
