controller-testing（控制器测试）

Controller Testing

When to Apply

Activate this skill only when the task is about Laravel controller feature tests (action-level HTTP behavior for a controller) and includes signals like:

• The test file path is under tests/Feature/Http/Controllers/** (including tests/Feature/Http/Controllers/Api/**). This is the primary trigger.
• The task is explicitly about a controller action and uses action-level describe('create' | 'destroy' | 'edit' | 'index' | 'show' | 'store' | 'update').
• Controller route assertions using route(...), nested parameters, and route-model binding scope checks.
• Auth/authorization outcomes and controller transport assertions:

- web/session (get, post, patch, delete, assertInertia, redirects), or - API/JSON (getJson, postJson, patchJson, deleteJson, JSON assertions).

Do not activate this skill based on describe('store') alone (many non-controller feature tests use the same verbs, for example Fortify/auth flows).

Do not use this skill for model/unit tests, service-layer tests, console commands, or non-HTTP behavior.

Kill Switch / Precedence

For controller-focused feature tests, this skill takes precedence over pest-testing. If pest-testing was selected for controller test work, stop and switch to controller-testing immediately.

Quick Start

# Create file only when needed
php artisan make:test --pest Http/Controllers/<Name>ControllerTest --no-interaction

# Run only the affected file
php artisan test --compact tests/Feature/Http/Controllers/<Name>ControllerTest.php

# Optional focused rerun
php artisan test --compact --filter="<test name>"

Decision Workflow

1. Inspect the controller action, form request, policy, resource, and route definition to derive the contract under test.
2. Choose transport mode: web/session or API/JSON.
3. Determine route shape (flat vs nested) and parameter keys.
4. For each action under test, apply this baseline in order (as applicable):

- requires authentication - policy denial (403) - binding mismatch (404) - validation datasets (store/update) - success response + persistence assertions

1. Load only the reference files needed for the action/rule pattern.

Output Guardrails (Keep Controller Tests Clean)

These guardrails exist to prevent noisy, inconsistent tests.

• Treat the controller contract as the source of truth. Templates are starting points only; adapt them to the actual request payload, response shape, redirects, resources, and policy flow implemented by the controller.
• Keep 403 tests minimal. For forbidden cases, you usually do not need to send a full payload (authorization should fail before validation).
• Validation datasets must be small and stable:

- Each dataset data should only include the field(s) needed to trigger that rule. Do not repeat a full "valid payload" for every case. - Assert validation messages for every failing field. Do not use keys-only expectations in these datasets. - When multiple fields share a sometimes|required-style blank-value rule, prefer one dataset case that submits blank strings for all of those fields and asserts the required message for each of them. Do not reduce that pattern to a single representative field. - Prefer post(...)/patch(...) directly; avoid from(...) unless you cannot get a reliable redirect-back assertion otherwise.

• Prefer route-based redirects: use assertRedirectToRoute(...) when a named route exists; use assertRedirect(...) only when the destination is not a named route or is config-driven.

Canonical 403 vs 404 Rule

Use this as the source of truth:

• If route bindings resolve correctly and authorization denies access, assert assertForbidden() (403).
• If route-model binding fails (wrong parent/child chain, scoped binding mismatch), assert assertNotFound() (404).

Actor context to keep outcomes deterministic:

• 403 tests: authenticate an in-scope actor that can resolve bindings but lacks permission.
• Validation and success-path tests: authenticate an authorized in-scope actor.
• 404 binding-mismatch tests: any authenticated actor is acceptable because binding fails first.

Reference Map

Load only what you need:

• API/JSON adaptation guide and full examples:

- references/modes/api-json.md

• Nested route naming and parameter composition:

- references/route-patterns.md

• Per-action templates (web/session-first):

- references/actions/create.md - references/actions/destroy.md - references/actions/edit.md - references/actions/index.md - references/actions/show.md - references/actions/store.md - references/actions/update.md

• Validation catalogs (merge only required rules):

- references/validation/store-validates-fields.md - references/validation/update-validates-fields.md

• Focused validation patterns (prefer first when matching rules exist):

- references/validation/required-with-and-array.md - references/validation/scoped-exists-and-unique.md - references/validation/prepare-for-validation.md - references/validation/api-login-validation.md

Action references are web/session-first templates. For API/JSON controllers, keep the same action structure and adapt assertions with references/modes/api-json.md based on the controller/resource contract under test.

Baseline Assertions by Transport

Web/session mode:

• requires authentication -> redirect to login route.
• Validation failures -> assertRedirectBackWithErrors(...).
• Page actions -> assertOk() + assertInertia(...).
• Mutation actions -> redirect + persistence assertions.
• Toast/flash assertions are optional and app-specific.

API/JSON mode:

• Protected endpoints: requires authentication -> assertUnauthorized().
• Public endpoints: skip auth-required test unless the endpoint is protected.
• Validation failures -> assertUnprocessable() + assertJsonValidationErrors(...).
• Success actions -> assertOk() / assertCreated() / assertNoContent() + JSON + persistence assertions.
• Assert validation messages, not just keys, so the test verifies the exact API contract.

Notes

• One-level, two-level, and three-level examples are patterns, not limits.
• For destroy, choose persistence assertions by model behavior:

- assertSoftDeleted(...) for soft-deleting models. - assertModelMissing(...) otherwise.

• Use the app's identifier shape in assertions (id, public_id, slug, route key).
