the typeorm-fixtures-test package works with PostgreSQL MySQL and SQLite.
If you're using an SQlite database the only thing you need to do is configuring the .env like in the .env.sqlite example.
this repository is a step by step demo of typeorm-fixtures-test with a postgres database, if you're a Mysql it works nearly the same way.
npm install
You have some sqlite and mysql env example files
The test fixtures are located in fixtures/dataFixtures
create user testuser superuser encrypted password 'password';
