# Database isolation
|
|
|
|
Run the suite with `composer test` or `vendor/bin/phpunit`. Both use
|
|
`tests/bootstrap.php`, which forces SQLite `:memory:` in all environment sources.
|
|
Tests never need a MySQL test database or the local database credentials.
|
|
|
|
`Tests\TestCase` rejects cached configuration and validates the default connection
|
|
before application providers boot. Its connection factory also rejects persistent
|
|
databases, URLs, and alternate endpoints for named or dynamically built connections.
|
|
Tests that need Laravel must extend this base class. Do not bypass these guards to
|
|
make a failing test pass; adapt database-specific tests to SQLite or use a separately
|
|
designed disposable database workflow.
|
|
|
|
`php tests/verify-database-safety.php` checks the guard and application wiring without
|
|
running test setup, queries, migrations, or opening PDO connections.
|
|
|
|
The suite does not validate MySQL-specific behavior when using SQLite.
