Rest Test Helper Laravel Package

Getting Started

This package is a thin, single-maintainer convenience layer over Illuminate\Testing\TestResponse. With 1 star, 0 dependents, and no documentation ecosystem, the honest starting position is: read the source first, then install. The whole src/ directory is almost certainly small enough to read in one sitting before you type a single test.

1. Install as a dev dependency only and pin it.

   composer require --dev kglogowski/rest-test-helper
   # or, deliberately:
   composer require --dev "kglogowski/rest-test-helper:^X.Y"
   

   Confirm the diff lands under require-dev, not require. A test helper leaking into production autoloads is the only way a package like this can do real damage.

2. Where to look first, in order:

   • src/ — find the entry point. Expect either a trait (e.g. RestTestHelpers) you use in a base TestCase, or a service provider registering TestResponse macros. This distinction determines the entire integration path, so resolve it before writing tests.
   • composer.json — check the illuminate/support / illuminate/testing constraint against your Laravel version. If it caps at an old major, stop here.
   • tests/ — if a suite exists, it is your real README. Copy call signatures from it verbatim.
   • README.md — likely terse; treat examples as claims, not guarantees.

3. Wire it up. If there is no extra.laravel.providers entry (common in packages this small), register the provider manually in tests/TestCase.php or phpunit.xml, or apply the trait to your base test case.

4. First use case — one real endpoint, both idioms side by side. Do not trust a helper you have not seen fail. Write the test twice:

   public function test_users_index_shape(): void
   {
       $response = $this->actingAs($this->user)->getJson('/api/users');
   
       // First-party baseline — always works
       $response->assertOk()->assertJsonStructure(['data' => [['id', 'email']]]);
   
       // Package helper — does it assert the same thing?
       $this->assertRestSuccess($response); // ← actual name from src/
   }
   

   Then deliberately break the endpoint (return 204, return malformed JSON, remove a key) and confirm the package helper actually goes red. A test helper that silently no-ops is the worst possible outcome — worse than no helper at all.

5. Decide within a day. If the helper does not materially beat assertOk()->assertJsonStructure([...]), remove it (composer remove --dev ...) and close the ticket. That is a successful evaluation, not a failed one.

Implementation Patterns

The patterns below assume the package exposes what its description advertises: request helpers per verb, JSON/status assertions, and auth/header convenience. Adapt names to whatever src/ actually declares.

Pattern 1 — Base test case as the seam. Never use the package trait directly in leaf tests. Apply it once to an abstract base, so that if you later replace the package with local helpers, the blast radius is one file:

abstract class ApiTestCase extends TestCase
{
    use RestTestHelpers; // the package trait
}

This is the single most important structural decision when adopting an unmaintained dependency.

Pattern 2 — Auth once per class, not per test. Use the package's header/authentication helpers in setUp so tests read as intent, not plumbing:

protected function setUp(): void
{
    parent::setUp();
    $this->withApiToken($this->token = Sanctum::actingAs(...));
}

If the package's auth helper returns a modified $this, verify it doesn't leak state between tests — setUp runs fresh per test in PHPUnit, but withHeaders accumulation is a known footgun.

Pattern 3 — CRUD lifecycle in a single test. The real day-to-day win is collapsing boilerplate so a full create-read-update-delete cycle stays readable:

public function test_post_lifecycle(): void
{
    $created = $this->postRest('/api/posts', ['title' => 'Hello']);
    $created->assertRestCreated();
    $id = $created->json('data.id');

    $this->getRest("/api/posts/{$id}")->assertRestOk()->assertRestKey('data.title', 'Hello');
    $this->patchRest("/api/posts/{$id}", ['title' => 'Bye'])->assertRestOk();
    $this->deleteRest("/api/posts/{$id}")->assertRestStatus(204);
}

Whether that reads better than postJson, assertStatus(201), assertJsonPath('data.title', ...) is the judgement call your spike must answer.

Pattern 4 — Data providers over copy-paste. Wrap the request helper in a #[DataProvider] to cover endpoint variants (paginated vs filtered vs sorted) without duplicating assertion blocks:

#[DataProvider('queryCases')]
public function test_index_filters(string $query, int $expectedCount): void
{
    $this->getRest("/api/users?{$query}")
        ->assertRestOk()
        ->assertRestCount($expectedCount);
}

Pattern 5 — Smoke suite against staging. The description's "smoke-test suites against staging" use case works if the package lets you point at a base URL. If it only wraps $this->getJson() (in-process), it is unit-test-only and cannot be used for a live smoke suite — check this early, it is a common misread of "REST test helper."

Pattern 6 — Keep the exit door open. Every assertion the package offers should be expressible in one line of first-party code. If you find yourself using a helper you cannot mentally translate to assertJsonPath, do not use that helper — it is now an undocumented DSL hiding in your suite.

Gotchas and Tips

• Silent no-op assertions are the primary risk. A helper with a mis-typed JSON path or a swallowed exception yields green tests over broken endpoints. Before you trust it, write a test against a deliberately wrong expected value and confirm it fails. Do this once per helper you adopt.

• Version drift is the second risk. Laravel's testing APIs have shifted across 8.x–11.x (assertValid, fluent response chaining, JSON path semantics). With zero dependents and likely no CI matrix, assume it has not been validated against your pinned version. Check the illuminate/* constraint in composer.json before writing anything you'll have to rewrite.

• The package is require-dev, but it still executes in CI. Dev dependencies run with pipeline credentials and cache access. If your org has SBOM or dependency-register requirements, this package will trip them on reputation alone — plan for that conversation, or vendor the source.

• Service provider and autoload conflicts. Minimal packages sometimes ship a provider that isn't auto-discovered, or a trait whose method names (get(), post()) collide with TestCase internals. If you see "trait method not applied" or unexpected $this->get() behaviour, check for name shadowing — rename your usage, not the trait.

• Trait conflicts with Pest / custom base classes. If your suite uses Pest expectations or your own ApiTestCase assertions, adding this creates a second parallel idiom. Half-package, half-first-party assertions is a readability tax paid on every test review. Pick one idiom per module.

• Header state can accumulate across a test. Many withHeaders-style helpers mutate the instance rather than returning a copy. Assert in isolation if you call an auth helper multiple times, or you may pass auth headers from a previous test's identity.

• Watch assertStatus vs assertOk semantics. A helper named assertRestSuccess that accepts only 2xx will pass on 204; a helper that checks for 200 exactly will fail on any 201 Created. Read the implementation — the difference between "success range" and "exact code" is where half the subtle assertion bugs live in wrapper libraries.

• Document what a failure means. With no Stack Overflow corpus and no issue history, your on-call engineer sees a red test and a helper name they've never heard of. If you adopt this, spend 20 minutes writing an internal note mapping each helper to its first-party equivalent. That note is the actual value you get out of the package — it lets you fork and replace with no knowledge loss.

• Extension point: fork. The realistic long-term move for a package this thin is to copy the two or three genuinely useful helpers into tests/Support/ and drop the dependency. MIT makes this clean. Budget roughly the same engineering hours as a proper evaluation spike, and you end up owning the code. That is the intended exit, not the fallback.
