SpringBoot - Testing with Flyway and H2 database

Question

I'm coding acceptance tests with Cucumber, and I want to use a H2 database for the tests.

The application-test.properties looks like:

server.port:8090

spring.jpa.database=H2
spring.database.driverClassName=org.h2.Driver
spring.datasource.url:jdbc:h2:mem:database_user;DB_CLOSE_ON_EXIT=FALSE
flyway.locations=classpath:resources/db/migration
flyway.enabled=true

spring.datasource.username:SA
spring.datasource.password:

spring.h2.console.enabled=true
spring.jpa.show-sql=true

security.basic.enabled:false
spring.application.name=userService

In the directory resources/db/migration, I have a sql file with these scripts:

create table user_image(
 id int unsigned not null AUTO_INCREMENT,
 url varchar(1000) not null,
 s3_key varchar(200) not null,
 PRIMARY KEY (id)
);


create table user (
    id int unsigned not null AUTO_INCREMENT,
    email varchar(50) not null,
    password varchar(100) not null,
    first_name varchar(50) not null,
    last_name varchar(50) not null,
    description varchar(50),
    phone_number varchar(50),
    user_image_id int unsigned,
    need_refresh_pass boolean not null,
    PRIMARY KEY (id),
    CONSTRAINT fk_user_image FOREIGN KEY (user_image_id)
    REFERENCES user_image(id)
);

But when I run the tests, H2 creates the schema with default format instead of using the scripts:

As you can see, all the VARCHAR are created with 255 size, instead of the real value.

Could you help me to integrate flyway with H2?

Thanks!

1- Make sure that your hibernate DDL generation is disabled:

spring.jpa.hibernate.ddl-auto=none

2- Make sure that the name of your SQL migration script respects flyway's convention. i.e.

V1__create_user_table_for_test.sql
