Testing

The bundle's tests

tests/Unit tests each class alone: the accepted currencies, the locale-aware decimal, the form type through a form factory, each constraint with Symfony's ConstraintValidatorTestCase, the Twig filter in an environment, the column type on a platform, and the bundle's configuration, services and prepended Doctrine configuration.

tests/Functional boots a kernel in fr_CA with FrameworkBundle, TwigBundle and DoctrineBundle on SQLite: a price entered in a form, the constraints with their French messages, the filter, and a Product whose price is stored in two columns, read back and summed.

From the root of the monorepo:

vendor/bin/phpunit packages/money-bundle/tests

Installed on its own:

composer install
vendor/bin/phpunit --no-configuration tests

Mutation testing kills every mutant of src/.

Testing an application's forms and entities

• Set the locale the test reads in: Locale::setDefault('fr_CA'), restored after the test. An amount typed as 1 234,50 reads differently in en.
• Submit strings, as a browser does: ['amount' => '19,99', 'currency' => 'CAD'].
• Compare amounts with equals() or on minorUnits, not with assertSame() on two objects.
• Keep a test of an entity round trip when an embedded Money is added: it catches a missing mapping or column type before production.

Benchmarks

The phpbench benchmarks in tests/Benchmark/ measure format_money over listings of one to five hundred prices, with the kept formatter and with a new one per price. From the monorepo root:

composer bench -- packages/money-bundle/tests/Benchmark
