Smoke Test

3 min • Beginner

Smoke test means: do a very quick check to see whether the app is basically working at all.

Summary: Check quickly that the app is alive.

Here are the endpoints we want to test quickly:

$home = $client->request('GET', $server['url'] . '/');
$api = $client->request('GET', $server['url'] . '/api/lessons');
$detail = $client->request('GET', $server['url'] . '/api/lessons/php-basics');

Now we can create a test like this:

$this->assertSame(200, $home['status']);
$this->assertSame(200, $api['status']);
$this->assertSame(200, $detail['status']);

Why this test works

This test is about important URLs, not about one class.
That is why the file lives in tests/http.
Put this file in tests/http/SmokeTest.php because it hits real endpoints.
Keep smoke tests very short.
Only check the most important paths.
Simple rule: if these fail, the app probably has a big problem.

Real-life examples

Example: on a company website, check that /, /login, and /contact all return status 200.
Example: on a shop website, check that /, /products, and /cart all respond without crashing.

Remember this

Put file in tests/http
Keep it short
Run with php tests/run.php smoke
