Adds `bundle exec rails test:all_databases` which runs the full test suite against every test database configured in database.yml in a single command. Convention: any top-level key starting with "test" that contains a Hash is a test database. `test:` is the required primary; `test_<name>:` blocks are optional additional adapters (e.g. test_sqlite, test_pg). For each configured database the task: 1. Checks the required adapter gem is available (skips with warning if not) 2. Runs `rails db:test:prepare` to create and migrate the database 3. Runs `rails test` and records pass/fail 4. Prints a summary and exits non-zero if any database failed Mechanism: a RAILS_DATABASE_YML env var points each subprocess to a temporary database.yml that contains only the current test config. config/application.rb(.dist) reads this var and overrides Rails' database config path before initialisation, so no monkey-patching of the test runner is required. config/database.yml.dist is updated with documented examples for SQLite and PostgreSQL additional test databases.

Run the full test suite against every test database configured in database.yml.
|
||
|
||
Any top-level key that starts with "test" and contains a Hash is treated as a
|
||
test database configuration:
|
||
|
||
test: # always required — the primary test database
|
||
adapter: mysql2
|
||
database: fixinme_test
|
||
...
|
||
|
||
test_sqlite: # optional additional databases
|
||
adapter: sqlite3
|
||
database: db/fixinme_test.sqlite3
|
||
|
||
test_pg:
|
||
adapter: postgresql
|
||
database: fixinme_test
|
||
...
|
||
|
||
For each database the task will:
|
||
1. Check that the required adapter gem is available (skip with warning if not).
|
||
2. Run `rails db:test:prepare` to create/migrate the database.
|
||
3. Run `rails test` and record pass/fail.
|
||
|
||
A summary is printed at the end. The task exits non-zero if any database fails.
