Naming Conventions

The plugin discovers tests by class, method, and function naming conventions — no attributes required.

Plugin class: NamingConventionPlugin\Testo\Convention\NamingConventionPlugin. Not included in default plugins.

Recognized patterns:

• Class + Method — *Test suffix on class and test* prefix on methods
• Function — test* prefix on function

final class UserServiceTest
{
    public function testCreatesUser(): void { /* ... */ }

    public function testDeletesUser(): void { /* ... */ }

    public function testUpdatesProfile(): void { /* ... */ }
}

function testEmailValidator(): void { /* ... */ }

You can customize suffixes and prefixes, and allow or disallow private method discovery:

new SuiteConfig(
    // ...
    plugins: [
        new NamingConventionPlugin(
            caseSuffix: 'Test',
            testPrefix: 'test',
            allowPrivate: false,
        ),
    ]
),

When to Use

Use naming conventions when:

• You prefer implicit test discovery without extra attributes
• You're migrating from PHPUnit or other frameworks that use similar patterns
• You want tests to be recognizable at a glance by their names
